Dermaceutic TCA peels are medical devices reserved for dermatologists and aesthetic physicians. Do not attempt to self-medicate.
TCA (trichloroacetic acid) is a «medium» peel - it reaches the superficial dermis. This distinguishes it from superficial AHA peels and justifies the credibility of the entire consumer range.
| Professional peeling | TCA concentration | Main indication |
| Cosmo Peel 15% | TCA 15% | First session - introduction, dull complexion, small spots |
| Cosmo Peel 18% | TCA 18% | Accustomed skin, moderate photoaging, irregular texture |
| Cosmo Peel 20% | TCA 20% | Moderate wrinkles, settled hyperpigmentation, acne scars |
| Cosmo Peel 30% | TCA 30% | Marked wrinkles, advanced photoaging, senescent skin |
«I use Dermaceutic peels in my practice for patients with advanced photoaging, settled acne scars and hyperpigmentation resistant to topical care. TCA is the tool between cosmeceuticals and lasers. The Dermaceutic consumer range is what I recommend for preparation and maintenance.»
Activ Retinol Dermaceutic is one of the top 3 retinol serums on the accessible French market - alongside SVR Ampoule [A] and Paula's Choice Retinol 1%. Three criteria set it apart: pure retinol at displayed concentration, integrated anti-irritant active ingredients, airless bottle.

Expert deciphering
Pure retinol 0.5% + ceramides + vitamin C derivative + vitamin E + panthenol + allantoin. Airless bottle. Perfect BeautyDecoded score (5/5 out of 5 reviews). Anti-ageing score: 90.1 and dark spots: 88.4 - among the best in the catalog. Dry skin score: 88.2 and normal to dry skin: 91 - optimal profile. Sensitive skin score: -2.5 - slight caution, consistent with pure retinol.
The 5 BeautyDecoded reviews are unanimously positive, with high-quality feedback. An exceptional signal: one user declares this retinol «his favorite» after testing Geek & Gorgeous, The Ordinary and Paula's Choice - a direct comparison with market references, in favor of Dermaceutic. Another confirms the overall improvement of the skin (imperfections, fine lines) after gradual introduction. A third warns of the implications of the new EU regulations (limit of 0.3%).
Oily skin score: 59.5 - moderate, consistent with anti-irritant ceramides and fats. The opinion «perfect for oily skin» (which applies to 1.0%) applies differently to 0.5%. Airless bottle: a decisive formulatory quality criterion for retinol conservation.

Verdict: - TOP - Rated 5/5 out of 5 reviews. Anti-ageing 90.1, spots 88.4. Compared favorably vs competitors. Airless bottle. Sensitivity score -2.5: gradual introduction mandatory.

Pure Retinol 1.0% - same formula as 0.5% with double the concentration. Rated 5/5 out of 3 reviews. Anti-ageing score: 93.5 and spots: 93.5 - the best in Dermaceutic's catalog. Dry skin score: 88.2. Sensitive skin score: -3.7 - slightly more cautious than 0.5%, consistent with the higher concentration.
The 3 BeautyDecoded reviews cover three distinct profiles: oily skin (excellent anti-aging and anti-acne results, 1 evening/2 max), combination skin (airless pump format appreciated, moisturizing required), sensitive skin (tolerated in 1 evening/3 after progression from 0.5%). Remarkable signal: sensitive skin tolerates 1.0% after a gradual increase from 0.5% - validation of the recommended progression protocol.
EU regulations: the forthcoming limit of 0.3% in consumer cosmetics is reported as a concern in the 0.5% notices and also applies to this 1.0%. Dermaceutic offers reformulation via its professional channels - to be checked according to date of purchase.
My analysis
«Activ Retinol 1,0% is the most powerful retinol serum in Dermaceutic's catalog (anti-aging and blemishes 93.5). Reserved for experienced profiles who have tolerated 0.5% well for 3+ months. Confirmed efficacy on acne and hyperseborrhea in addition to anti-aging. Sensitive skin score -3.7: progress since the mandatory 0.5%».»
Verdict: - TOP - Rated 5/5 out of 3 reviews. Anti-aging and blemishes 93.5 (best in catalog). Acne + anti-aging effectiveness confirmed. Progression since 0.5% mandatory.

5.0/5 «Perfect for oily skin - concentrated serum, ideal as anti-aging and against pimples. Beware of irritation: 1 evening out of 2 max with SPF the next day.»
5.0/5 «The best is the tube format with airless pump. You don't need much product. Moisturize your skin at the same time.»
5.0/5 «Very good retinol. My sensitive skin tolerates it in 1 evening out of 3. I had started with 0.5% before switching to this one.»

Pure AA 15% + ascorbysilane 14.5% + vitamin E + ferulic acid. Anti-ageing score: 90.1 and dark spots: 90.1 - among the best in the catalog. Oily skin score: 84 and normal to oily skin: 91 - optimal profile. Dry skin score: 0 - contraindicated (alcohol in 4th INCI position). Sensitive skin score: -7.0 - unsuitable.
The 2 BeautyDecoded reviews are of the highest quality: one user alternates it with tretinoin (medical use on prescription) and confirms its effectiveness on melasma - a sign of confidence in the formulation and expert use. The other confirmed its radiance and luminosity after 6 months, with just one drawback: the smell.
Important signal: use in alternation with tretinoin (vitamin A acid, medical use) signals an expert user profile, positioning this serum as a serious addition to a dermatological routine. The reported odor (characteristic of pure AA which partially oxidizes) is a signal of partial stability - use quickly after opening, despite the airless bottle.

My analysis
«Tri Vita C30 is the best vitamin C serum in Dermaceutic's catalog - double formula pure AA + derivative, anti-aging and spots 90.1, confirmed melasma efficacy. Dry skin score 0: contraindicated (alcohol in 4th INCI). Sensitive skin score -7.0. Reserved for non-sensitive oily to combination skin. Odor is a signal of partial oxidation - use promptly».»
Verdict: - TOP - Anti-aging and spots 90.1. Score 5/5. Confirmed melasma effectiveness. Alcohol: contraindicated for dry, sensitive skin. Odor to be monitored.

Kojic acid 1.6% + alpha-arbutin + liquorice + Morus alba + AHA/BHA. Blemishes score: 76.5 and spots: 76.5 - high. Dry skin score: 84 - suitable. Normal to dry skin score: 91 - optimal. Sensitive skin score: -6.5 - unsuitable. Score 5/5 on 2 reviews.
The 2 BeautyDecoded reviews are instructive and contrasting. One confirms remarkable effectiveness on recent acne scars («visible elimination week after week»). The other is more cautious after 1 month's use on blemishes («no results yet - blemishes unfortunately take a very long time»). This contrast reflects the clinical difference between recent scars (faster resolution) and established blemishes (8-16 weeks minimum).
Anti-aging score: 79.9 - relevant for an anti-spot concentrate with AHA/BHA. Local use on recalcitrant blemishes - not for overall application. Kojic acid + alpha-arbutin cover two distinct tyrosinase inhibition mechanisms - documented anti-spot synergy.
My analysis
«Yellow Cream is Dermaceutic's benchmark local anti-spot concentrate (blemishes and spots 76.5). BeautyDecoded reviews perfectly illustrate the clinical difference: recent scars (quick results) vs established blemishes (8-16 weeks mandatory). Sensitive skin score -6.5: local use only on limited areas, not overall application.»
Verdict: - TOP - Stains and blemishes 76.5. Score 5/5. Fast results on recent scars. Established blemishes: patience 8-16 weeks. Sensitive skin -6.5: local use only.

5.0/5 «Incredible on my recent acne scars - visible elimination week after week.»
5.0/5 «I've been testing it for 1 month every evening for my spots - no results yet. I'm going to stick with it because blemishes unfortunately take a very long time. Pleasant product to apply.»

Methylsilanol pectinate 25% + vitamin A (retinyl palmitate) + vitamin E + panthenol B5. Sensitive skin score: -0.5 - almost optimal for a vitamin C skin care product. Spots score: 76.5 - relevant. Anti-ageing score: 66.3. Normal to oily skin score: 87.5. Score 5/5 on 1 review - insufficient basis.
The only BeautyDecoded review is remarkably precise: visible difference in 2 weeks on spots AND fine lines, light texture, rapid penetration. Strong signal of rapid results even with a vitamin C derivative (vs. pure AA). The rapid results reported in 2 weeks are consistent with the topical antioxidant (rapidly visible daily protection) and anti-spot action of methylsilanol pectinate.
Sensitive skin score -0.5: the best tolerance of any vitamin C skin care product in Dermaceutic's catalog (vs. -7.0 for Tri Vita C30). This is precisely its advantage for skin that has poorly tolerated pure AA. Dry skin score 63.7: moderate - less rich formula than Hyal Ceutic, but sufficient for daily use.
My analysis
«C25 Cream is Dermaceutic's best vitamin C option for sensitive skin (sensitive skin -0.5 vs -7.0 for Tri Vita C30). Confirmed results in 2 weeks on spots and fine lines. Optimal sensitive skin score among the vitamin C skincare products in the catalog. Better Q/P ratio than Tri Vita C30 for this profile».»
Verdict: - TOP (sensitive and intolerant skin AA pur) - Sensitive skin -0.5. Spots 76.5. 2 weeks results confirmed. 1 opinion statistically insufficient.

Night cream for acne-prone skin. Oily skin score: 84 and normal to oily skin score: 91 - optimal profile. Blemishes score: 76.5 and spots: 76.5 - high. Sensitive skin score: -7.75 - the lowest in the Dermaceutic catalog. Score 5/5 out of 1 review. This product is not in the source article - discovered via CSV.
The only review confirms a direct medical recommendation (recommended by an aesthetic doctor) and a definitive adoption on combination skin with imperfections («I can't do without it anymore»). A strong signal of confidence and effectiveness for a committed professional profile. Dry skin score: 58.8 - not suitable for this profile.
Sensitive skin score -7.75: the lowest in the catalog, consistent with a formula designed for acne-prone skin (active ingredients probably exfoliating or antibacterial). For normal to oily non-sensitive skin only. An interesting BeautyDecoded discovery for adult acne routines.
My analysis
«Activabiome is Dermaceutic's discovery from the BeautyDecoded base - rating 5/5, confirmed aesthetic doctor recommendation, definitive adoption on combination skin with imperfections.

Repairing balm with panthenol. Sensitive skin score: +2.25 - exceptional for a Dermaceutic product, the best in the catalog on this criterion. Dry skin score: 84 and normal to dry skin score: 91 - optimal profile. Redness score: 76.5 - high. Oily skin score: 0 - contraindicated. Score 4/5 on 1 review.
The only review (4/5) is very instructive: use described as emergency and recovery care after tretinoin abuse or drying treatments. Use around the eyes or mouth for areas of intense dryness. Confirmed non-comedogenic. This is precisely the most intelligent clinical positioning of this balm: barrier recovery care after strong active ingredients, not daily care.
Sensitive skin score +2.25: the best sensitive skin score in Dermaceutic's catalog - confirms post-irritation reparative use. Redness score 76.5: relevant for the soothing action of panthenol. BeautyDecoded discovery missing from source article.
My analysis
«Panthenol Ceutic is the most interesting discovery in the Dermaceutic catalog - sensitive skin +2.25 (the best in the catalog) and redness 76.5. Confirmed optimal use: recovery care after concentrated tretinoin, retinol or AHAs. Oily skin 0: for dry skin only. Score 4/5 - specific use, not daily use.»
Verdict: - Recovery care reference - Sensitive skin +2.25 (best catalog). Redness 76.5. Post-irritation use confirmed. Oily skin 0: contraindicated. BeautyDecoded discovery.
BeautyDecoded user reviews (1 review in total)
4.0/5 «Vaseline-like texture - nice to apply, doesn't aggravate my acne. Soothing after tretinoin abuse or drying treatment. Ideal for use around the eyes or mouth in cases of severe dryness.»
Alcohol is present in Tri Vita C30 (4th INCI position), C25 Cream (end of formula) and Foamer 15. For dry, sensitive or damaged skin, alcohol potentiates the dehydrating effect of AHAs and vitamin C. BeautyDecoded data confirms this signal: Tri Vita C30's dry skin score is 0 (contraindicated).
Dermaceutic SPFs use methoxycinnamate (octinoxate) - a UV filter whose regulatory status is under scrutiny in Europe. For a range that treats photoaging, an SPF with new-generation filters (Tinosorb S/M, Uvinul A Plus) would be more coherent. Prefer an external SPF (Anthelios UVMune 400).
Dermaceutic formulas are priced between €30 and €70 for 30 ml. This price is justified for products with concentrated active ingredients (Activ Retinol, Tri Vita C30), but less obvious for basic moisturizers (Hyal Ceutic).
The Hyal Ceutic cream is presented as suitable for combination to oily skin by the brand - this is not consistent. The quantity of plant oils and film-forming agents is too high for combination to oily skin, and risks clogging pores. Reserved for dry to very dry skin.
Dermaceutic or Eneomey for glycolic acid?
Both marquess have serious, well-documented AHAs. The main difference: Eneomey goes up to 30% of AHAs for the general public, Dermaceutic tops out at 15%. For a beginner or intermediate profile: both are equivalent. For a senescent profile with advanced photoaging: Stim Renew 30 Eneomey is more powerful. For the combination of AHA + cleanser in a simple routine: Foamer 15 Dermaceutic is one of the best galenic formulas on the market.
Will Dermaceutic retinol disappear under the new EU regulations?
New European regulations limit cosmetic retinol to 0.3% in face care products. This directly affects Activ Retinol 0.5% and 1.0%. Some BeautyDecoded users have already pointed out this problem in their reviews. Dermaceutic offers reformulations via its professional channels. Check production date and regulatory compliance on products purchased.
How to combine Dermaceutic retinol with anti-spot skincare products?
Recommended protocol: Activ Retinol on evenings without exfoliation, Yellow Cream or Radiance Cream alternately on other evenings. Do not use AHA and retinol on the same evening. In the morning: Tri Vita C30 or C25 Cream + SPF 50+ (essential, otherwise the entire anti-spot treatment will be thwarted).
Is Dermaceutic compatible with pregnancy?
No for most of the range. Retinol (Activ Retinol, Mela Crime): contraindicated during pregnancy. Concentrated AHAs (Foamer 15, Turn Over): not recommended as a precaution. Vitamin C (Tri Vita C30, C25): generally accepted, confirm with your doctor. Compatible products: Panthenol Ceutic (sensitive skin +2.25) and Oxy Biome (niacinamide + probiotics). Please consult your doctor.
What is the BeautyDecoded application?
BeautyDecoded enables users to choose cosmetics adapted to their skin type, thanks to artificial intelligence which analyzes INCI formulations and generates compatibility scores for 80 skin types. 7 Dermaceutic products have been identified in the database. Remarkable: all have a score of 5/5 (except Panthenol Ceutic at 4/5) - a signal of the high quality perceived by BeautyDecoded users across the entire catalog.
