Further information
Analyse a Cosmia product on your skin profile.
The BeautyDecoded application lets you scan any cosmetic product to visualize its suitability for your skin type and needs, based on INCI analysis - particularly useful for objectively verifying Cosmia marketing claims against actual INCI composition («collageneer» demystified on Anti-Wrinkle Night Cream, «sensitive» to be interpreted in mass-market logic, octinoxate indicated on SPF30 anti-aging cream) and to identify the rare references suited to your profile within a mostly fragranced catalog (Crème 30+ Q10 + body balms).
Formulation positioning
An Auchan private label - accessible everyday cosmetics with formulatory arbitration.
Cosmia is the cosmetics brand distributed exclusively by Auchan Group banners, launched for offer affordable daily care. This is the first private label analyzed by the BeautyDecoded project. - a new editorial positioning that complements the marques sensory premium (Rituals, Pure Altitude), active-centric premium (Ole Henriksen) and dermo-cosmetics (SVR, La Roche-Posay) already analyzed. The range covers all everyday needs face and body cleansers, moisturizers, anti-ageing care for the first wrinkles, sun protection, hygiene, complemented by a range of products Cosmia Bio Cosmos certified. The positioning is clear: make routine cosmetics affordable. This mass-market logic implies recurring formulatory trade-offs use of economical anionic surfactants (SLES) in cleaners, use of perfume in almost all references, previous-generation organic UV filters in the solar range. The Cosmia Bio range (3 references analyzed) offers a distinct formulation profile, more restrictive on these ingredients.. BeautyDecoded catalog lists 80 Cosmia references (77 Cosmia + 3 Cosmia Bio), with a majority of cleansers (45 products) and creams (23 products). Algorithmic analysis reveals an average score for sensitive skin of -5.39 (median -6.5)., a overall low tolerance profile according to the BeautyDecoded grid - point that structures the entire analysis.
01
Assets actually present in the catalog (and those absent)
Four genuinely documented active ingredients emerge from the INCI analysis of the 80 references : niacinamide (vitamin B3, found in Pure Mattifying Care), azelaic acid (Pure mattifying care), ubiquinone (coenzyme Q10) present in the First Wrinkle range, and ascorbyl glucoside (stable form of vitamin C, Glow Sérum Cosmia Bio). Niacinamide with a minimum 5 % has a solid scientific literature concerning reinforcement of the skin barrier through stimulation of endogenous ceramides, sebum regulation and inhibition of melanosome transfer (Draelos 2005). Concerning azelaic acid, efficacy in mild to moderate acne and rosacea has been documented. However, Cosmia does not disclose the concentration, which limits the comparative evaluation.. Q10 (ubiquinone) has interesting mitochondrial antioxidant literature, but remains an auxiliary active in cosmetology., whose measurable clinical anti-aging effect remains modest compared to retinoids or peptides (Knott 2015). Analysis reveals total absence of retinol and retinoids - l’cosmetology's best-documented anti-aging active ingredient (Kafi 2007) - in the entire Cosmia catalog. This absence is consistent with a retail positioning that favors assets with no specific usage constraints (gradual introduction, photosensitization, contraindication to pregnancy), but it mechanically limits the range's corrective anti-aging potential.. Peptides and AHAs (glycolic, lactic acid) are also absent from the references analyzed.
02
Formulatory vigilance - fragrance, surfactants, octinoxate
Perfume (PARFUM, and its compounds Linalool, Limonene, Geraniol, Citronellol, Citral) is present in almost all Cosmia references analyzed., including in the «sensitive» range» - editorial point to note. Cleansers are mainly based on the combination of SODIUM LAURETH SULFATE (SLES) + mild surfactants. : SLES is less irritating than SLS but still classified as an aggressive anionic surfactant, which mechanically explains the very low sensitive skin scores of shower gels and cleansing gels (between -8.5 and -10.6). On the suncare range, a major formulatory point to note : presence of octinoxate (Ethylhexyl methoxycinnamate) in SPF30 Anti-Aging Face Cream. Octinoxate is the subject of substantial literature on its potential endocrine-disrupting activity. (Kunisue 2012) and its documented toxicity to coral reefs, which is why it has been banned in several jurisdictions. (Hawaii, Palau). Drugstore dermo-cosmetics references (SVR Sun Secure, La Roche-Posay Anthelios UVMune 400) have withdrawn octinoxate from their formulations. The Cosmia Bio brand excludes some of these ingredients from its Cosmos certification., which doesn't mean we can rule out natural fragrances - Citral, Limonene of citrus essential oils remain regulated allergens regardless of their natural or synthetic origin.
Editorial reading
Cosmia is consistent with its positioning as an Auchan private label - the first private label analyzed by the BeautyDecoded project. Affordable, everyday range with formulatory choices: economical anionic surfactants (SLES), systematic fragrance, previous-generation organic UV filters. Average score for sensitive skin -5.39 - consistent with this formulation logic.
Four documented assets are worthy of note: the Pure mattifying care (azelaic acid + niacinamide, imperfections 55.2 catalog record), the 30+ Q10 Cream (sensitive skin +0.40 - a rare tolerance exception in the catalog), the Glow Serum Vit C Cosmia Bio (62.9 catalog record spots), and the body range (the most convincing segment in terms of Q/P).
Three critical angles to note: total absence of retinol/retinoids - limits corrective anti-aging potential; «collageneer» is a trade name with no real INCI active ingredient (no Matrixyl/Argireline/copper peptide); SPF30 Cream contains octinoxate (endocrine disruptor Kunisue 2012, banned Hawaii/Palaos).
For non-reactive skin looking for an affordable daily routine: consistent. For sensitive skin: only Crème 30+ Q10 and body balms. For a serious corrective anti-aging protocol: an external retinoid remains necessary (Retinal The Ordinary €14.90, Retinol Typology €29.90, SVR Ampoule A €35).
Methodological specificity
A 100 % algorithmic analysis - 80 INCI references without BD user reviews.
Cosmia analysis presents a methodological specificity to be honestly pointed out to the reader. The BeautyDecoded database contains 80 algorithmically analyzed Cosmia references but no user reviews registered on this catalog at the time of writing - as for Ole Henriksen, Pure Altitude and The MASK Dr.
This analysis is therefore based exclusively on two objective sources : BeautyDecoded algorithmic scores (based on analysis of complete INCI lists and weighting by skin profile according to 80 skin types referenced in the application) and detailed examination of INCI compositions. Lack of BD reviews reflects Cosmia's «Auchan private label» positioning - exclusive supermarket distribution, less represented in the BD user base (which leans towards marques active-centric and dermo-cosmetics). Methodological consequences : (1) the strengths of this analysis - the breadth of the catalog (80 references) enables complete objective mapping Cosmia formulatory signature, identification of assets actually documented vs. absent, demystifying marketing claims not supported by the actual INCI («collageneer», «sensitive»), dated UV filters (Kunisue octinoxate 2012); (2) the limits of this analysis - lack of validation through real user feedback means that successful use cases (non-reactive consumers looking for an accessible daily routine) are not digitally documented in the BD database. For the consumer use this analysis as a indicative formulatory mapping, and To be completed by a mandatory 48-hour patch test before adoption on reactive skin.
Range overview
The seven ranges in the Cosmia catalog - thematic mapping.
The catalog analyzed includes 80 references (77 Cosmia + 3 Cosmia Bio) divided into 7 theme ranges 45 cleansers, 23 creams, and other formats spread throughout the daily routine.
| range | Skin target | Main products |
|---|---|---|
| Face Hydration | For all skin types on a daily basis | Crème hydratante fraîcheur, Crème hydratante sensitive, Eau micellaire |
| Anti-ageing 30+ / Q10 | First wrinkles, 25-35 years | Q10 Day Cream, Collagener Night Cream, Q10 Eye Contour |
| Expert Duo Age | Confirmed anti-aging, 40+ years | Day cream, Night cream, Firming serum, Eye contour cream |
| Pure (azelaic) | Combination to oily skin, blemishes | Matifying care with azelaic acid, Pure cleansing gel |
| Cosmia Bio (Cosmos) | Certified organic routine | Glow Sérum Vitamine C, Crème éclat, Eau micellaire bio |

| Body cleansers | Daily hygiene for all | Shower gels, shower milks, body scrubs |
Catalog asset mapping
Active ingredients present and absent from the Cosmia catalog - formulatory pedagogy.
Objective mapping of assets actually documented in the Cosmia catalog and clinical reference anti-aging / anti-spot actives absent. This teaching method calibrate anti-aging / anti-spot / anti-acne expectations according to catalog positioning.
| Documented assets | Cosmia presence | Reference | Clinical position |
|---|---|---|---|
| Niacinamide (vitamin B3) | ✅ Present | Pure mattifying care | Documented ≥ 5 % (Draelos 2005) |
| Azelaic acid | ✅ Present | Pure mattifying care (concentration not given) | Documented 15 % reference (Sieber & Hegel 2014) |
| Q10 (ubiquinone) | ✅ Present | Anti-ageing 30+ range | Antioxidant booster (Knott 2015) |
| Vitamin C (ascorbyl glucoside) | ✅ Present (derived form) | Glow Sérum Cosmia Bio | Bioavailability < L-ascorbic acid (Pinnell 2001) |
| Retinol / retinoids | ❌ Absent | - | Best-documented anti-aging active ingredient (Kafi 2007) |
| Bioactive peptides (Matrixyl, Argireline, copper) | ❌ Absent | - | Documented anti-aging active ingredients collagen stimulation |
| AHA (glycolic, lactic, mandelic acid) | ❌ Absent | - | Documented active ingredients for keratolysis + blemishes |
| Routine BHA (salicylic acid) | ❌ Absent in dedicated formula | - | Anti-acne reference (BHA 2 % Paula's Choice) |
| Vitamin C L-ascorbic acid 10-20 % | ❌ Absent | - | Anti-stain clinical reference (Pinnell 2001) |
| Anti-stain tranexamic acid | ❌ Absent | - | Documented anti-melasma reference |
The absence of retinol and peptides mechanically limits Cosmia's corrective anti-aging potential. This absence is consistent with a retail positioning that favors assets with no specific usage constraints (gradual introduction, photosensitization, contraindication for pregnancy, SPF 50+ mandatory in the morning). For a serious corrective anti-aging protocol, a external retinoid remains necessary. Cross-project comparison : Retinol 0.3 % Typology (~€29.90, anti-aging 93.5, 5/5 out of 3 BD reviews - 5-ingredient formula, Q/P project reference) ; Retinal 0.2 % The Ordinary (~14.90 €, anti-aging 93.5 - retinaldehyde even more effective according to Sorg 1999); ; SVR Ampoule [A] Lift Rétinol (~35 €, encapsulated retinol concentrations 0.3 / 0.6 / 1 %); ; Clinical Vitamin A Theramid (~50 €, anti-aging 95.2 record project - tri-retinoid HPR + Retinol + Retinal). For concentrated spot protection : Liftactiv B3 Vichy (~35 €, stains 95.2 record any BD base - niacinamide + tranexamic acid AHA-free, alcohol-free, fragrance-free). For a BHA acne treatment : BHA 2 % Paula's Choice (blemishes 85 - project anti-acne reference).

Preventive anti-aging Q10 - Crème 30+ (exception tolerance +0.40) and Crème nuit collageneer démystifiée
Two anti-aging products for the first wrinkles in the 25-35 age group. 30+ Q10 Cream obtains sensitive skin +0.40 - rare profile in the catalog to report. Collageneer night cream obtains anti-aging 59.5 catalog record BUT the «collageneer» claim is demystified No peptides stimulating collagen synthesis in the actual INCI.
Preventive anti-aging day cream 30-40 years - sensitive skin +€0.40 exception catalog
Sensitive skin +0.40 - rare profile in the catalog - Q10 + argan oil + shea + AH
First Wrinkles Day Cream 30+ with Q10
Formula centered on ubiquinone (Q10), mitochondrial antioxidant coenzyme naturally present in the skin, whose concentration decreases with age. Association with argan oil (oleic acid, vitamin E), shea butter and sodium hyaluronic acid. UV filters (butyl methoxydibenzoylmethane and octocrylene), suggesting a basal photoprotective effect. but no SPF claimed. The sensitive skin score of +0.40 is noteworthy: this is one of the few creams in Cosmia's catalog adapted to reactive skin according to the BeautyDecoded grid.. Anti-ageing score 54.4 - high for a retinoid-free formulation - driven mainly by the Q10 / HA / shea combination.

Suitable for sensitive skin (score: +0.40). A rare profile in the Cosmia catalog. However, it does contain fragrance.
Source: Knott A et al. Topical treatment with coenzyme Q10-containing formulas improves skin's Q10 level. Biofactors. 2015.
" It's a relevant option for the 30-40 age group looking for accessible anti-aging hydration.. The positive sensitive skin score is unusual for Cosmia and is a real selling point.. Limits to be aware of : the Q10 remains an adjuvant with a modest effect compared to retinoids - for a corrective anti-aging strategy, this formulation does not replace a retinol protocol. Cross-project comparison for a serious corrective anti-aging 30-40 years, prefer Retinol 0.3 % Typology (~€29.90, anti-aging 93.5, 5/5 out of 3 BD reviews), Retinal 0.2 % The Ordinary (~€14.90, anti-aging 93.5 - Q/P reference), or SVR Ampoule [A] Lift Rétinol (~35 €, encapsulated). To be considered as a routine day care. »
Verdict - Affordable preventive anti-aging reference with the right tolerance profile. Sensitive skin +0.40 catalog exception. Modest expected effect, consistent with preventive positioning. Q10 active adjuvant - not a substitute for a corrective retinoid.
Anti-wrinkle night cream - collagener claim demystified
Anti-ageing 59.5 record catalog by emollient effect - «collageneer» trade name, no real INCI peptide
Anti-wrinkle night cream with collagener
The term «Collageneer» is a Cosmia trade name and not a standardized INCI active ingredient.. Analysis of the list reveals a formulation focused on vegetable butters and oils. (shea, argan) with a complex of emollient glycerides. Presence of tocopherol (vitamin E) as an antioxidant. Important: no collagen-synthesis-stimulating peptides (Matrixyl, Argireline, copper peptides) can be identified in the INCI list.. The claimed «anti-wrinkle» mechanism is based on emollient/hydrating and antioxidant effects - not on direct stimulation of dermal collagen..

⚠ Sensitivity verdict
Slight caution (score: -0.25). Presence of fragrance to be noted. Rich texture may stain combination skin.
Collagener« demystified - a trade name, not a standardized INCI active ingredient. Analysis of the INCI list reveals no peptides stimulating collagen synthesis (Matrixyl/Palmitoyl Tripeptide-1, Argireline/Acetyl Hexapeptide-8, copper peptides/GHK-Cu). The claimed «anti-wrinkle» mechanism is based on emollient/hydrating and antioxidant effects (plant butters and oils, tocopherol) - not on direct stimulation of dermal collagen.. This nuance is essential for calibrating expectations. It's a case comparable to the «Retin-ALT» Ole Henriksen demystified in a previous analysis of the project - marketing naming evocative of an active ingredient that does not correspond to the actual INCI composition. This practice is legal as long as the ingredients mentioned are actually present. (which is not the case for «collageneer», which is not an INCI), but it deserves an editorial note. For real bioactive peptides with documented collagen stimulation : Copper Peptide Theramid (~€50, anti-aging 86.7 - GHK-Cu Pickart 2018 + bifida ferment + 4 peptides); ; Multi-Peptides + Copper 1 % The Ordinary (~€16.60, anti-aging 88.4 - concentrations communicated, 8× cheaper than Theramid); ; Argireline Solution 10 % The Ordinary (~€6, Argireline pure); ; Peptides Copper Nooance (anti-aging 91.8 - project reference).
" The anti-ageing score of 59.5 is the highest in the Cosmia catalog, but it needs to be put into context. it reflects a rich moisturizing and nourishing formulation, not a corrective protocol. It's a good option for dry skin as part of a night-time routine.. For a truly corrective anti-aging strategy, this cream is not a substitute for a retinoid - which does not exist in the Cosmia catalog.. Collageneer« naming is misleading : the consumer can understand that a real collagen-stimulating active ingredient is present, which is not the case. Systematic verification of the actual INCI remains the only way to objectify the composition.»
Verdict - Nourishing night cream - anti-wrinkle by emollient and moisturizing effect, not by direct collagen stimulation. Anti-ageing 59.5 record catalog through moisturizing effect. Collagener« claim demystified - no actual peptide in INCI. For documented peptides: Multi-Peptides + Copper 1 % The Ordinary (€16.60) Q/P reference.

Visit Pure mattifying care with azelaic acid is the the most relevant imperfections reference in the Cosmia catalog. Imperfections 55.2 catalog record. Azelaic acid + niacinamide combination - two documented assets. Formulatory limit : azelaic acid concentration not provided and its position as 15th INCI suggests a much lower concentration than the 15 % clinical reference (Skinoren).

Imperfections 55.2 catalog record - azelaic acid + niacinamide BUT azelaic concentration not given
Pure mattifying care with azelaic acid
The formula combines two documented assets : azelaic acid (natural dicarboxylic acid with keratolytic, anti-bacterial action on Cutibacterium acnes and anti-inflammatory properties) and niacinamide (sebum regulation, barrier action). The concentration of azelaic acid is not communicated by Cosmia. : its position as the 15th INCI ingredient suggests a much lower concentration than the 15 %s used in clinical references (SVR Flash Ampoule, Skinoren). Presence of kaolin and magnesium aluminium silicate : absorbent mattifying effect consistent with positioning.

Cosmia Bio éclat - Glow Serum Vitamin C (spots 62.9 record, organic paradox + natural allergens)
Visit Cosmos-certified organic Cosmia range offers 3 references (Glow Sérum, Crème éclat, Eau micellaire bio). Glow Vitamin C Serum obtains 62.9 spots - best score in the Cosmia catalog thanks to ascorbyl glucoside. A formulatory paradox the Cosmos organic certification does not eliminate natural fragrance allergens (Citral, Limonene, Linalool from orange essential oil) - Sensitive skin score -3.25.

Stains 62.9 record Cosmia catalog - ascorbyl glucoside + orange extract BUT natural allergens (Citral + Limonene + Linalool)
Glow Serum with vitamin C (Cosmia Bio)
The main asset is ascorbyl glucoside, a glycoside derivative of vitamin C. Formulation advantage : superior stability to pure L-ascorbic acid, low sensitivity to oxidation. Documented disadvantage : requires cutaneous enzymatic conversion to release active vitamin C, which reduces bioavailability compared to L-ascorbic acid at 10-20 % (Pinnell 2001). Spot score of 62.9 - the best in the Cosmia catalog analysed - supported by the anti-tyrosinase action of derived vitamin C combined with orange extract (citrus aurantium). The presence of gluconolactone (light PHA) adds a gentle exfoliating effect.

Source: Pinnell SR et al. Topical L-ascorbic acid: percutaneous absorption studies. Dermatol Surg. 2001.
Organic formulation paradox - Cosmos certification does not eliminate natural allergens. The presence of Citral / Limonene / Linalool allergens (naturally derived from orange essential oil) explains the -3.25 sensitive skin score.. Cosmos organic certification does not eliminate allergenicity - fragrance allergens regulated by the SCCS (Scientific Committee on Consumer Safety) since 1999, supplemented by 56 new substances subject to mandatory reporting in 2023, retain their skin-sensitizing potential regardless of their natural or synthetic origin. Common allergic mechanism : air oxidation and formation of allergenic peroxides - hence the increased risk on products that have been open for several months. For sensitive skin looking for a tolerant, organic vitamin C serum, there are alternatives: Vitamin C 11 % SAP Typology (~12.50 €, same type of SAP stable derivative, sensitive skin 0, rated 4.75/5 on 2 BD reviews - fragrance-free); ; Pure Vitamin C 10 La Roche-Posay (~32 €) ; SVR Ampoule C.
" This is the most relevant spot/glare-targeted option in the Cosmia catalog, at an affordable price.. Formulatory limitations: the presence of Citral / Limonene / Linalool allergens (naturally derived from orange essential oil) explains the -3.25 sensitive skin score - Cosmos organic certification does not eliminate allergenicity. For a stronger anti-spot effect, L-ascorbic acid at a minimum of 10 % remains the clinical reference.. Cross-sectional comparison of the anti-task project : Liftactiv Sérum B3 Vichy (~35 €, stains 95.2 record any BD base - niacinamide + tranexamic acid AHA-free alcohol-free fragrance-free); ; AZID Theramid (~38 €, spots 88,4 + redness 93,5, 5/5 out of 5 BD reviews) ; Mela B3 La Roche-Posay (~€32, stains 90.1 - niacinamide + tranexamic acid) »

Critical formulatory cases - SPF30 Cream (octinoxate), Sensitive Cream (limited claim), Cleansing Gel (SLES + fragrance)
Three formulatory cases that illustrate the limits of the Cosmia retail paradigm. SPF30 Anti-Aging Face Cream contains octinoxate (Ethylhexyl methoxycinnamate) - potential endocrine disruptor Kunisue 2012, dismissed by dermo-cosmetic references. Sensitive moisturizing cream : claim «sensitive» to be interpreted as a retail marketing benchmark, not standard dermo-cosmetics. Refreshing cleansing gel : SLES + fragrance + 3 allergens - sensitive skin score -9.50.
Sun Care Face SPF30 Anti-Aging - octinoxate endocrine disruptor
Kunisue octinoxate 2012 endocrine disruptor - banned Hawaii/Palaos coral reef toxicity - rejected by contemporary dermo-cosmetics
Protective face cream SPF30 Anti-ageing
UV filtration with organic cocktail : Ethylhexyl methoxycinnamate (octinoxate), Octocrylene, Butyl methoxydibenzoylmethane and Diethylhexyl butamido triazone. Octinoxate is the subject of substantial literature on its potential endocrine-disrupting activity. (Kunisue 2012) and its documented toxicity to coral reefs, which is why it has been banned in several jurisdictions. (Hawaii, Palau). In comparison, dermo-cosmetic references from pharmacies (SVR Sun Secure, La Roche-Posay Anthelios) have withdrawn octinoxate from their formulations. The presence of this ingredient in the Cosmia formula is the most questionable formulatory point in the catalog analyzed..

Not suitable for sensitive skin (score: -3.00). Octinoxate potential endocrine disruptor - dermo-cosmetic alternative strongly recommended.
Source: Kunisue T et al. Benzophenone-type UV filters and octinoxate in human urine. Environ Sci Technol. 2012.
Octinoxate - potential endocrine disruptor and filter banned in several jurisdictions. Octinoxate (Ethylhexyl methoxycinnamate) is documented as a potential endocrine disruptor. with animal studies showing effects on hormone production (Kunisue 2012). Its documented toxicity to coral reefs has led to its prohibition in several jurisdictions. : Hawaii (ban effective 2021), Palau, certain marine protected areas. The European SCCS maintains octinoxate as an authorized filter, but under supervision. Contemporary dermo-cosmetic references have withdrawn octinoxate in favor of modern cocktails (Tinosorb S, Uvinul A Plus, Mexoryl 400). For daily anti-aging suncare over many years, octinoxate-free alternatives are preferable. Cross-project comparison : Anthelios UVMune 400 LRP (~25 €, Mexoryl 400 long UVA 380-400 nm, octinoxate-free, Octocrylene-free - absolute reference long UVA); ; SVR Sun Secure Blur SPF50+ (modern Tinosorb filters, sensitive skin) ; Hyalu-Cica Water-Fit Sun Serum Skin1004 (~22 €, 22 BD reviews rating 4.91/5, sensitive skin +1.5 - Q/P universal project reference).
" Daily sun protection remains the most documented anti-aging preventive intervention - based on this principle, this solar product fulfils its UV filtration function. The limiting formulatory point is clear the presence of octinoxate, rejected by contemporary dermo-cosmetic references. For daily anti-aging use, I suggest comparing this formulation with octinoxate-free alternatives.. The price differential vs Anthelios UVMune 400 LRP (€25 with Mexoryl 400 long UVA) or Skin1004 Sun Serum (€22 with 22 reviews 4.91/5) remains modest vs Cosmia (~€8)., and far superior filtration quality/long-term tolerance. »
Verdict - Functional SPF30 suncare, but dated formulation. Octinoxate potential endocrine disruptor (Kunisue 2012) - banned Hawaii/Palaos coral reef toxicity. Alternative with modern filters for everyday use. Prefer Anthelios UVMune 400 LRP (€25) or Hyalu-Cica Sun Serum Skin1004 (€22)..
Sensitive« moisturizing cream - mass-market claims demystified
Claim «sensitive» supermarket - less aggressive formulation than average catalog BUT fragrance + octocrylene + propylene glycol present
Sensitive moisturizing cream
Visit Sensitive« positioning is a common marketing feature in supermarkets. However, the INCI analysis qualifies the claim : presence of octocrylene and butyl methoxydibenzoylmethane (UV filters with photoprotective effect), perfume and mineral oil (isohexadecane). Borage oil (documented gamma-linolenic acid) is the main active ingredient. - relevant to the skin barrier.

⚠ Sensitivity verdict
Slight caution (score: -0.95). Despite its «sensitive» positioning, the presence of octocrylene + perfume + propylene glycol limits its theoretical suitability for the most reactive skins.
«Sensitive» retail vs. dermo-cosmetics - claims education. The term «sensitive» is to be understood here in a mass-market logic. : less aggressive formulation than the catalog average, but does not correspond to the proven dermo-cosmetic standard for sensitive skin. Dermo-cosmetic products for sensitive skin (Avène Tolérance Extrême, La Roche-Posay Toleriane Sensitive, SVR Sensifine) are systematically fragrance-free, alcohol-free and contain documented thermal waters. and filtration of excipients at risk of sensitization. For confirmed reactive skin, Q10 Crème 30+ (score +0.40) or non-Cosmia references are more suitable.. Cross-project comparison : Toleriane Sensitive Cream LRP (~€16, fragrance-free, alcohol-free - documented reference for sensitive skin); ; Avene Hydra Cream Extreme Tolerance (fragrance-free, Avene thermal spring water) ; Cicaplast Baume B5 LRP (~€13, fragrance-free panthenol concentrate); ; Bariéderm-Cica Gel-Cream Uriage (~17 €, isotonic thermal spring water + Cica, sensitive skin +0.5).

Verdict - Sensitive« claim for supermarkets - less aggressive formulation than catalog average, but dermo-cosmetic standard not met. Presence of perfume + octocrylene + propylene glycol. For reactive skin: prefer Crème 30+ Q10 Cosmia (+0.40) or Toleriane LRP (€16) / Avène Tolérance.
Facial cleansing gel - SLES + fragrance + allergens contraindicated for sensitive skin
Sensitive skin score -9.50 - SLES + fragrance + 3 fragrance allergens (Linalool + Geraniol + Citronellol) - contraindicated for sensitive skin
Fresh face cleansing gel
Classic surfactant formulation for mass-marketing : SLES (Sodium Laureth Sulfate) as main surfactant, complemented by mild surfactants (Decyl Glucoside, Cocamidopropyl Betaine, Coco-Glucoside). SLES is less irritating than SLS but still classified as an aggressive anionic surfactant. The cumulative presence of PARFUM and three regulated allergens (Linalool, Geraniol, Citronellol) explains the -9.50 score. A useful comparison : dermo-cosmetic cleansers for sensitive skin (Avène Cleanance, La Roche-Posay Toleriane) are based on SLES- and fragrance-free bases, which objectively materializes the expected tolerance delta.

Verdict - Sensitive skin score -9.50 - contraindicated for sensitive, reactive skin, rosacea. SLES + fragrance + 3 regulated allergens. A good option for non-reactive skin looking for an economical routine cleanser.. For sensitive skin: Toleriane LRP (€10) or Avène Tolérance.
Comparative positioning
Cosmia vs. dermo-cosmetic and asset-centric references - arbitration according to the expected formulatory rigor.
Comparison of Cosmia's positioning with adjacent positions : dermo-cosmetics pharmacy (SVR, La Roche-Posay) and active-centric entry-level (The Ordinary).
| Criteria | Cosmia | SVR (dermo) | The Ordinary |
|---|---|---|---|
| Positioning | Retail Auchan | Pharmacie dermo | Active-centric accessible |
| Retinol | Absent | Present (encapsulated 0.3 / 0.6 / 1 %) | Present (0.2 % / 0.5 % / 1 %) |
| Azelaic acid | Present (conc. not given) | Present (15 %) | Present (suspension 10 %) |
| Octinoxate-free solar | No (octinoxate present) | Yes (modern filters) | Not concerned |
| Concentration indication | No | Yes | Yes (systematic) |
| Sensitive skin range | Sensitive (limited claim) | Sensifine (clinical) | Limited |
| Average serum price | 8-12 € | 18-35 € | 6-15 € |
Synthetic reading - Cosmia in the accessible mass-market segment. Cosmia is clearly positioned on the price criterion, but without the rigor of its formulas. (concentrations communicated, dated filters removed, sensitive skin standardized) that dermo-cosmetic references provide. The Ordinary occupies an interesting mid-range position at a similar price., with concentrated assets systematically communicated. For a consumer who values maximum affordability and accepts formulatory trade-offs (systematic perfume, dated filters, marketing claims to be verified), Cosmia is consistent. For consumers seeking the most rigorous formulation at the best price, The Ordinary is more affordable, with a superior price/performance ratio.. For confirmed sensitive skin or for a serious corrective anti-aging protocol, dermo-cosmetic references remain essential (SVR Sensifine + Ampoule A, LRP Toleriane + UVMune 400).

Frequently asked questions
Everything you need really know.
Is Cosmia a French brand?
Cosmia is the private label of the Auchan group, distributed exclusively through the group's banners. Products are formulated and manufactured on behalf of Auchan by various, mainly European, manufacturers.. Private label status explains its affordable price positioning.
Is Cosmia suitable for sensitive skin?
Visit average score for sensitive skin in the Cosmia catalog is -5.39 (median -6.5), indicating a overall profile not suitable for reactive skin according to the BeautyDecoded grid. Some specific references are exceptions (30+ Q10 cream at +0.40, body balms at 0). For confirmed sensitive skin, dermo-cosmetic ranges formulated without fragrance or anionic surfactants are more suitable. (Avène Tolérance Extrême, La Roche-Posay Toleriane Sensitive, SVR Sensifine).
Does Cosmia offer retinol?
No. An analysis of the 80 references in the catalog reveals no retinol or retinoid.. The absence of this active ingredient - the best documented in anti-aging cosmetology - limits the range's corrective potential.. For a corrective anti-aging strategy, consider a brand offering this active ingredient : SVR Ampoule [A] Lift Rétinol (~35 €, encapsulated 0.3 / 0.6 / 1 %), The Ordinary Retinal 0.2 % (~€14.90, anti-aging 93.5), Retinol 0.3 % Typology (~€29.90, anti-aging 93.5, 5/5 out of 3 BD reviews), Clinical Vitamin A Theramid (~50 €, anti-aging 95.2 record project).
What's the difference between Cosmia and Cosmia Bio?
Cosmia Bio is the Cosmos Organic-certified version of Cosmia. (3 references analyzed: Glow Sérum, Crème éclat, Eau micellaire bio). This certification implies the exclusion of certain synthetic ingredients (silicones, PEG, synthetic fragrances) but does not eliminate natural fragrance allergens (Linalool, Limonene, Citral from essential oils). Considerations for sensitive skin profiles. Natural allergens retain their skin sensitizing potential regardless of their origin - common allergic mechanism through air oxidation and peroxide formation.
Is Cosmia suncare suitable for daily anti-aging use?
Cosmia's SPF30 anti-ageing sun cream fulfils its UV filtration function but its formulation contains octinoxate (ETHYLHEXYL METHOXYCINNAMATE), filter identified as potential endocrine disruptor (Kunisue 2012) and removed contemporary dermo-cosmetic references. For daily anti-aging use, more modern alternatives are preferable : Anthelios UVMune 400 La Roche-Posay (~25 €, Mexoryl 400 UVA long 380-400 nm, octinoxate-free, Octocrylene-free); ; Hyalu-Cica Water-Fit Sun Serum Skin1004 (~€22, 22 BD reviews 4.91/5, sensitive skin +1.5).
What is the «collageneer» mentioned by Cosmia?
Visit collageneer« is a Cosmia trade name and not a standardized INCI active ingredient. An analysis of the INCI list for Anti-Wrinkle Night Cream reveals no peptides that stimulate collagen synthesis. (Matrixyl, Argireline, copper peptides). The claimed anti-wrinkle effect is based on the moisturizing and emollient effect of plant butters (shea, argan), not on direct stimulation of dermal collagen.. This practice is legal as long as no specific active ingredient is falsely claimed in the INCI., but it deserves editorial attention to calibrate consumer expectations. For real, documented bioactive peptides : Multi-Peptides + Copper 1 % The Ordinary (~€16.60, anti-aging 88.4), Copper Peptide Theramid (~50 €, anti-aging 86.7), Peptides Copper Nooance (anti-aging 91.8 - project reference).

BeautyDecoded is a cosmetic analysis application using artificial intelligence and is not a medical diagnostic tool. Cosmia is the Auchan Group's private label, distributed exclusively in the Group's stores - its products are not medical devices. This analysis is based on 80 Cosmia references algorithmically analyzed by BeautyDecoded, with no user reviews recorded on this catalog. at the time of writing. This analysis is therefore based exclusively on algorithmic formulation scores and detailed examination of INCI lists.. Average score for sensitive skin -5.39 (median -6.5) - low overall algorithmic tolerance profile, consistent with a mass-market positioning. Total absence of retinol/retinoids in the catalog analyzed - mechanically limits the range's corrective anti-aging potential. No documented collagen-stimulating bioactive peptides (Matrixyl, Argireline, copper peptides). No AHA (glycolic, lactic and mandelic acids) and vitamin C L-ascorbic acid 10-20 % reference concentration. Claim/INCI mismatches reported editorially : (1) «The »collageneer" in the Anti-Wrinkle Night Cream is a Cosmia trade name and not a standardized INCI active ingredient. - no peptide stimulating collagen synthesis can be identified in the actual INCI (2) The «sensitive» claim of Sensitive Moisturizing Cream is to be interpreted in retail logic - less aggressive formulation than the average catalog, but dermo-cosmetic standard not met (presence of fragrance + octocrylene + propylene glycol). Octinoxate precautions (present in SPF30 Anti-Aging Face Cream) : filter identified as potential endocrine disruptor (Kunisue 2012) and toxic to coral reefs, banned in Hawaii and Palau. The European SCCS maintains octinoxate as an authorized filter, but under supervision. Contemporary dermo-cosmetic references have withdrawn octinoxate - prefer Anthelios UVMune 400 LRP (Mexoryl 400 long UVA) or SVR Sun Secure Blur SPF50+. Precautions Cosmia Bio the Cosmos Organic certification does not eliminate natural fragrance allergens (Citral, Limonene, Linalool from citrus essential oils) - their skin sensitizing potential is documented regardless of their natural or synthetic origin. Precautions azelaic acid concentration not communicated (Pure mattifying care) : cosmetic concentration probably well below the 15 % clinical reference level (Skinoren, SVR Ampoule Flash Azélaïque, AZID Theramid) - expected clinical efficacy modest. Precautions vitamin C derived from ascorbyl glucoside (Glow Sérum Bio) : reduced bioavailability compared with L-ascorbic acid 10-20 % (Pinnell 2001) - anti-spot clinical reference concentrated L-ascorbic residue (CE Ferulic SkinCeuticals). 48-hour patch test on forearm mandatory before facial use for all new active ingredients for reactive skin - particularly important for Cosmia, given the unfavorable average score for sensitive skin in the catalog (-5.39). SPF 50+ morning mandatory on all anti-aging routines incorporating photosensitizing active ingredients. For sensitive skin looking for tolerant dermo-cosmetic alternatives, If you're on the go, opt for Avène Tolérance Extrême, SVR Sensifine, La Roche-Posay Toleriane Sensitive. For a serious corrective anti-aging protocol, An external retinoid is still necessary - prefer Retinol 0.3 % Typology (€29.90), Retinal 0.2 % The Ordinary (€14.90), SVR Ampoule A (€35), Theramid Clinical Vitamin A (€50). For concentrated, dose-dependent spot protection Liftactiv B3 Vichy (€35, stains 95.2 record any BD base). In the event of a skin reaction to a cosmetic, stop use immediately and consult a health professional. This article does not constitute a commercial partnership with the Cosmia brand.
