Theramid is a line of active serums developed by NicheBeautyLab, positioned in the premium clinical skincare segment. The catalog is composed exclusively of serums - 10 references identified in the BeautyDecoded database, each targeting a specific problem with specifically documented active ingredients. The brand's central distinguishing feature is the transparency of the formulas' INCI information.
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 arbitrating between the 10 serums in the Theramid catalog according to your personal profile (Lino-8 sensitive skin / AZID rosacea / Clinical Vitamin A corrective anti-aging / Copper Peptide retinoid-free anti-aging / HAPCA Filler hydration) and for calibrating a protocol for the gradual introduction of a powerful retinoid like Clinical Vitamin A.
L'detailed examination of the INCIs of the 10 Theramid serums highlights formulation rigor superior to the clean beauty premium market average. Several objective factors support this observation. About retinoids : three distinct serums targeting different levels of retinoid commitment - A Retinyl Retinoate (retinaldehyde + mild ester), Clinical Vitamin A (tri-retinoid HPR + Retinol + Retinal), Copper Peptide (anti-aging without retinoid). This stratification enables gradual clinical ramp-up. About peptides Copper Peptide specifically identifies the Copper Tripeptide-1 (GHK-Cu) in 6th position INCI - clinically documented anti-aging peptide reference (Pickart 2018). Derma-Peptides combines 5 different bioactive peptides identified one by one (Acetyl Hexapeptide-1, N-Prolyl Palmitoyl Tripeptide-56, Acetyl Tetrapeptide-2, Palmitoyl Tripeptide-38, Tripeptide-1) - sophisticated cosmetological stratification. About ceramides Ceramide Treatment identifies by name 5 different types (NG, NP, AP, AS, NS, EOP) - higher level of transparency than most marquess who make do with generic Ceramide NP. AZID also contains 5 ceramides in addition to azelaic acid. On anti-stain Even In serum combines tranexamic acid + arbutin + kojic acid + nonapeptide-1 + azelaic derivative + carnosine + lactobionic + mandelic acid - multi-mechanism anti-stain formulation unusual in the clean beauty segment.
Visit Theramid's first objective distinguishing feature is transparency on the exact nature of assets. Most of the marques ceramides on the market communicate «contains ceramides» without specifying either types or concentrations - a generic Ceramide NP at the bottom of the INCI list is enough to validate the communication. Theramid specifically identifies 5 different types of ceramide (NG, NP, AP, AS, NS, EOP) in Ceramide Treatment and AZID. each type targets a distinct biological function of epidermal intercellular cement (see dedicated biological table below). The same rigor applies to peptides: 5 bioactive peptides identified in Derma-Peptides, GHK-Cu mentioned by name in Copper Peptide with its precise INCI position. This transparency enables clinically informed INCI reading that most marquess make impossible through communication opacity. It's a good point to recognize objectively, which distinguishes Theramid from marques, which has a similar marketing positioning but lower formula transparency.
Visit Theramid price positioning (~38 to 50 €/30 ml) is located well above the dermo-cosmetic references available on the market on comparable segments. For ceramides Ceramide Treatment Theramid ~50 € vs. CeraVe Moisturizing Cream ~€12/340 g (reference available with MVE Technology and independent published clinical data). For peptides Copper Peptide ~50 € vs. The Ordinary Buffet + Copper Peptides 1 % ~€30 (reported concentrations, published data). For azelaic acid 15 % AZID ~38 € vs Nooance Clarifying Care ~€35 (AA 15 % + BHA, independent data). The price differential must be weighed according to the value attributed to (1) the superior formulative transparency Theramid on the exact nature of the assets; (2) the cumulative ceramide diversity (5 types vs. 1-3 among competitors); (3) the global premium formulative quality with multi-asset stratification; (4) the BeautyDecoded user feedback (5/5 out of 5 reviews for AZID, 4.25/5 out of 2 reviews for C-Tetra E.F.), confirming the effectiveness of our flagship products. For a consumer whose budget favors accessibility with documented assets at communicated concentrations, The Ordinary, SVR or La Roche-Posay remain serious alternatives at much lower prices. For specific problems where Theramid is superior (AZID 15 % on rosacea with exceptional tolerance confirmed 5/5 out of 5 reviews), price arbitrage may tip in Theramid's favor.
" Ceramides are one of the active ingredients I talk about most in my consultations.. Not because it's trendy - because it's biologically based. Reconstituting intercellular cement with the same molecules naturally present in the skin is the most rational approach to treating a deficient barrier. Among marques ceramides, Theramid stands out for its transparency. 5 ceramides identified by name in Ceramide Treatment, repeated in other references (AZID, HAPCA Filler). It's a good thing to recognize. BeautyDecoded analysis confirms this structural diagnosis: AZID is the leading formulative reference with redness score 93.5 exceptional, sensitive skin +0.1 (remarkable result for an active ingredient with 15 %, which is usually irritating), rated 5/5 out of 5 reviews - tolerance on rosacea is confirmed by BD users who report finally tolerating an AA 15 % after abandoning it with other marquess. Lino-8 is the tolerance nugget of the catalog Sensitive skin +2.5 catalog record, no irritants detected in INCI - for patients with sensitive skin, rosacea or post-procedure skin (laser, peel), Theramid serum should probably be prescribed first. Clinical Vitamin A is the most powerful cosmetic retinoid formulation in the catalog with anti-aging 95.2 Theramid catalog record and among the best BeautyDecoded anti-aging scores of all catalogs combined (in Retinol 0.3 % Typology, Retinal 0.2 % The Ordinary, Retinol 0.3 SkinCeuticals - all at 93.5). but reserved for retinoid-experienced profiles (≥ 6 months without irritation), Strictly contraindicated for reactive and rosaceous skin, and during pregnancy and breastfeeding. The price differential with accessible dermo-cosmetic references remains the main arbitration factor. - For consumers who value premium formulative transparency and sophisticated multi-active layering, Theramid offers a consistent level of quality; ; for consumers seeking the best asset-price ratio, More affordable alternatives exist (CeraVe for ceramides, The Ordinary for peptides, Nooance for azelaic acid). Three editorial recommendations : (1) for rosacea and azelaic acid 15 % with documented tolerance AZID is the reference in the catalog and one of the most effective anti-redness serums in the entire BD database; (2) for sensitive, rosaceous or post-procedure skin Lino-8 as first-line treatment (no irritants detected, sensitive skin +2.5 record); (3) for powerful corrective anti-aging in retinoid-savvy profiles Clinical Vitamin A in very gradual introduction (1 evening/week × 4 weeks, then 2 evenings, then 3), SPF 50+ morning mandatory, contraindicated for pregnancy and breast-feeding».»
Visit ceramides are the main lipids in epidermal intercellular cement - about 50 % of stratum corneum lipids. This cement holds the corneocytes together Cells are the bricks, lipids are the mortar. When ceramides decline (age, UV, aggressive detergents, atopic dermatitis), the consequences are direct : transepidermal dehydration, loss of barrier function, skin fragility. Mapping of the 5 ceramide types identified by Theramid and their specific biological roles.
| Ceramide type | Biochemical structure | Role in the skin barrier |
|---|---|---|
| Ceramide 1 (EOS / EOP) | Esterified fatty acid + sphingosine or phytosphingosine | Bridge between lipid lamellae - barrier cohesion |
| Ceramide 3 (NP) | Non-hydroxy fatty acid + phytosphingosine | Hydration and skin suppleness |
| Ceramide 6-II (AP) | Alpha-hydroxy fatty acid + phytosphingosine | Regulation of desquamation and intercellular cohesion |
| Ceramide AS / NS | Alpha-hydroxy / non-hydroxy + sphingosine variants | Structural complements of the lipid matrix |
| Phytosphingosine | Plant sphingoid base (precursor) | Ceramide precursor, anti-inflammatory action |
This article updates a previous analysis published by BeautyDecoded on Theramid, with two notable differences that justify a revised overall conclusion.
Sorted by decreasingly sensitive skin score. AZID and Lino-8 are the two references of first choice for sensitive or reactive skin. Clinical Vitamin A is the most powerful anti-ageing option but strictly contraindicated for sensitive skin (sensitive skin score -6.9, redness score -216.8 - the most negative in the catalog).
| Product | Target | Sensitive skin | Key score |
|---|---|---|---|
| Lino-8 | Soothing barrier | +2,50 | No irritants detected - Redness 76.5 - No opinion BD |
| HAPCA Filler | Deep hydration | +0,50 | Triple AH + ceramide NG - No BD Reviews |
| AZID - Azelaic acid 15 % | Redness / acne | +0,10 | Redness 93.5 - Imperf 88.4 - Spots 88.4 - 5/5 out of 5 reviews |
| C-Tetra E.F. (derived vitamin C) | Stains / sheen | 0,00 | Anti-ageing 83.3 - Spots 86.7 - 4.25/5 out of 2 reviews |
| Ceramide Treatment | Barrier (5 ceramides) | -0,20 | 5 named ceramides + ectoin |
| Copper Peptide | Global anti-aging | -0,50 | GHK-Cu + bifida ferment + 4 peptides - Anti-ageing 86.7 |
| Derma-Peptides | Preventive anti-aging | -0,50 | 5 identified bioactive peptides - Anti-ageing 76.5 |
| Even In | Multi-mechanism anti-tasking | -0,60 | Tranexamic acid + arbutin + kojic acid - Redness 91.8 |
| A Retinyl Retinoate | Mild retinoid anti-aging | -1,20 | Retinal + retinyl retinoate - Anti-ageing 86.7 |
| Clinical Vitamin A | Powerful corrective anti-aging | -6,90 | HPR + Retinol + Retinal - Anti-ageing 95.2 record |
L'AZID is the Theramid product that convinces doctors without reservation : documented active ingredient (azelaic acid 15 %), indicated concentration, hybrid formulation enriched with 5 ceramides + carnosine, exceptional redness score (93.5), optimal sensitive skin score (+0.1) on a 15 % active ingredient that usually irritates, BeautyDecoded rating 5/5 out of 5 reviews - the best in the Theramid catalog with a significant volume of reviews.
Azelaic acid 15 % - concentration corresponding to the clinically validated therapeutic threshold (15 % in cosmetics, 20 % in prescribed medical formulations). Hybrid formulation enriched with 5 identified ceramides (NP, EOP, NS, AS, AP), carnosine (antioxidant and anti-glycation), oat extract (Avena sativa) and acetyl tetrapeptide-2. This construction mechanically explains the higher tolerance observed. Ceramides support the barrier during the action of azelaic acid.
Three barrier and hydration serums with excellent tolerance profiles. Lino-8 is the tolerance nugget in the catalog : sensitive skin +2.5 - record score, no irritants detected in INCI. Ceramide Treatment is the’formulative expression of the Theramid signature with 5 ceramides identified by name. HAPCA Filler combine 3 forms of hyaluronic acid + ceramide NG + sphingolipids.
Barrier formulation built around panthenol (provitamin B5) in 2nd position INCI, linoleic acid in 3rd position (omega-6 essential fatty acid), precursor of endogenous ceramides), avocado oil, Saccharomyces ferment (fermented yeast rich in beta-glucans), phytonadione epoxide (vitamin K1), ubiquinone (Q10) mitochondrial antioxidant, and linolenic acid (omega-3). Sensitive skin score +2.5 - the highest in the Theramid catalog. NO irritants detected in INCI.
The the central formative element in Theramid's positioning a barrier serum with 5 specific ceramides named in the INCI - Ceramide NG (7th position), Ceramide NP (11th), Ceramide AP (12th), Ceramide AS (13th), Ceramide NS (14th), Ceramide EOP (15th). This targeted diversity covers the major types of epidermal ceramides. Presence of ectoin (natural protective osmolyte) and glycine soy (soy lecithin).
Combines three forms of hyaluronic acid (hydrolyzed HA, sodium acetylated hyaluronate, sodium hyaluronate implicite) with sphingolipids, phospholipids, ceramide NG and beta-glucan. Sensitive skin score +0.5 - positive. No irritants detected in INCI.
Four anti-aging serums with progressive power stratification. Clinical Vitamin A is the most powerful cosmetic retinoid formulation in the catalog with anti-aging 95.2 record - reserved for retinoid-resistant skin. A Retinyl Retinoate is the’gentle retinoid introduction (retinaldehyde + retinyl retinoate ester). Copper Peptide and Derma-Peptides offer a retinoid-free anti-aging alternative compatible with contraindicated profiles (pregnancy, breast-feeding, intolerance).
High-level tri-retinoid formulation combining three complementary molecules : Hydroxypinacolone Retinoate (HPR) - aka granactive retinoid, retinoic acid ester that binds directly to RAR receptors without the need for prior enzymatic conversion, unlike retinol, which requires two conversions. 11th INCI position. Also present Retinol (12th position) and Retinal (retinaldehyde) (13th position) - or a combination of the three major cosmetic retinoids. Anti-ageing score 95.2 - the highest in the Theramid catalog and among BeautyDecoded's top anti-aging scores across all catalogs.
Combination retinaldehyde + retinyl retinoate (mild ester form) + sodium retinoyl hyaluronate. Anti-ageing score 86.7 - solid. Sensitive skin score -1.2 - significantly more tolerant than Clinical Vitamin A (-6.9). A gentle introduction to retinoids.
Serum focused on Copper Tripeptide-1 (GHK-Cu) in 6th position INCI - the best-documented anti-aging copper peptide in cosmetology, studied for its effects on collagen synthesis, extracellular matrix remodeling and tissue repair (Pickart 2018). Complementary presence from bifida ferment lysate (topical probiotic), acetyl tetrapeptide-2, trifluoroacetyl tripeptide-2 (firming peptide), sh-oligopeptide-1 (biotech EGF) and sodium hyaluronate.
Sophisticated peptide layering combining : Acetyl Hexapeptide-1, N-Prolyl Palmitoyl Tripeptide-56 Acetate (peptide stimulating collagen synthesis), Acetyl Tetrapeptide-2, Palmitoyl Tripeptide-38 («matrikine» signaling peptide, simultaneously stimulates collagen, elastin, HA and fibronectin), and Tripeptide-1. This combination targets the main skin matrix remodelling pathways without the need for a retinoid.. Consistent 76.5 anti-aging score.
Two complementary anti-spot serums. C-Tetra E.F. (4.25/5 out of 2 comic book reviews) uses 3 stable vitamin C derivatives + ferulic acid - vitamin C tolerant for sensitive skin. Even In offers a multi-mechanism anti-spot formulation unusual in the clean beauty segment with tranexamic acid + arbutin + kojic acid + nonapeptide-1 + azelaic derivative - complete tri-action profile (spots 86.7 + redness 91.8 + anti-aging 66.3).
Formulation based on three stable vitamin C derivatives : ascorbyl tetraisopalmitate (THDA) in 2nd INCI position (lipophilic derivative, epidermal penetration without acid pH), ascorbyl glucoside in 4th position (water-soluble glycoside derivative), and ascorbyl methylsilanol pectinate. Remarkable presence of ferulic acid - antioxidant documented to stabilize vitamin C and potentiate its anti-free radical effect (Lin 2005).
Multi-mechanism anti-stain formulation unusual in the clean beauty segment. Combination of : tranexamic acid in 4th INCI position (plasmin inhibitor, documented action on melasma - Taraz 2017), arbutin and kojic acid (tyrosinase inhibitors), nonapeptide-1 (anti-pigment peptide), potassium azeloyl diglycinate (water-soluble derivative of azelaic acid), carnosine (anti-glycation), licorice extract anti-inflammatory and anti-pigmentary, lactobionic acid (PHA gentle exfoliant) and mandelic acid (AHA exfoliant). This multi-target stratification explains the tri-action profile.
Comparison of Theramid positioning with established references on comparable segments : ceramides (CeraVe, Avène, Byoma), azelaic acid (Nooance), retinoid (The Ordinary), copper peptides (The Ordinary).

«Ceramides are one of the active ingredients I talk about most in consultations. Not because it's trendy - because it's biologically sound. Replenishing intercellular cement with the same molecules naturally present in the skin is the most rational approach to treating a deficient barrier. Among marques ceramides, Theramid stands out for its transparency: 5 ceramides are specifically identified in Ceramide Treatment, and their presence is repeated in other references (AZID, HAPCA Filler). This is a good thing to recognize. BeautyDecoded's analysis confirms this structural diagnosis: AZID is the leading formulating reference, with an exceptional redness score of 93.5, sensitive skin +0.1 (a remarkable result for an active ingredient at 15 %, which is usually irritating), and a score of 5/5 out of 5 reviews.

Information for educational purposes only, not a substitute for medical consultation. BeautyDecoded is an artificial intelligence cosmetic analysis application and is not a medical diagnostic tool. Theramid is a cosmetics brand developed by NicheBeautyLab - its products are not medical devices. This analysis is based on 10 Theramid sera algorithmically analyzed by BeautyDecoded, including 2 references validated by user reviews (AZID 5/5 out of 5 reviews, C-Tetra E.F. 4.25/5 out of 2 reviews). This analysis updates an earlier conclusion published by BeautyDecoded on Theramid («AZID is the positive exception, the rest lack rigor») on the front page. a more nuanced reading reflecting the enrichment of the BD base from 2 to 10 sera analyzed. Retinoid precautions (Clinical Vitamin A, A Retinyl Retinoate) SPF 50+ morning mandatory for the entire duration of use and 4 weeks after discontinuation, strictly contraindicated during pregnancy and breast-feeding (documented teratogenicity of retinoids as a precautionary principle), do not combine with AHA/BHA on the same evening (so no simultaneous Clinical Vitamin A + Even In - alternate). Possible transient skin purging phenomenon when starting retinoids (transient accentuation of acne for 4-8 weeks) - expected reaction, not a permanent adverse effect. Clinical Vitamin A is strictly contraindicated on reactive, rosaceous or atopic skin. (Sensitive skin score -6.9, redness score -216.8 - the most negative in the Theramid catalog) - reserved for retinoid-experienced profiles (≥ 6 months' use of retinol at medium concentration without irritation). AZID (azelaic acid 15 %) and Even In (tranexamic acid) are traditionally not recommended as a precautionary measure during pregnancy, in the absence of documented absolute contraindication. Theramid pregnancy-compatible anti-aging routine Copper Peptide + Derma-Peptides + Lino-8 + HAPCA Filler (retinoid-free references). 48-hour patch test on forearm recommended before facial use for any new active ingredient on reactive skin, particularly for Even In due to its multi-ingredient complexity (kojic acid, mandelic, lactobionic). Realistic timeframe for anti-spot and anti-aging results 8-12 weeks minimum of regular use - not 2-3 weeks. The price differential between Theramid and accessible dermo-cosmetic references (CeraVe, The Ordinary, SVR, La Roche-Posay) must be weighed against the value attributed to Superior formulative transparency (ceramides 5 identified types, peptides 5 stratified, retinoids 3 levels), cumulative formulative diversity, premium workmanship. In the event of a skin reaction to a cosmetic, discontinue use immediately and consult a health professional.
