Retinol

A vitamin A derivative converted by skin into retinoic acid. One of the best-studied topical ingredients with proven anti-aging efficacy.

Anti-aging

Evidence by route

Topical application

Proven efficacy. Two or more independent RCTs with instrumental endpoints.

Randomized controlled trials confirm increased collagen production, reduced wrinkle depth, and improved skin texture with long-term use. Evidence is weaker than tretinoin because retinol requires enzymatic conversion and is less standardized in OTC concentrations.

Combinations with other ingredients

Works well with

NiacinamideНиацинамид

Niacinamide reduces retinol's irritation potential by strengthening the barrier without sacrificing efficacy.

Panthenol (Provitamin B5)Пантенол (провитамин B5)

Panthenol softens retinol adaptation in the first weeks. Reduces redness and flaking without blocking the main effect.

CeramidesЦерамиды

Ceramides restore the barrier that retinol weakens during adaptation. A must-pair for sensitive skin.

Does not combine with

Glycolic AcidГликолевая кислота

Using both in one routine raises irritation 2-3x. Alternate: retinol at night, AHA on a different evening.

Salicylic AcidСалициловая кислота

Simultaneous use raises irritation potential. Alternate every other day or split morning/evening.

Benzoyl PeroxideБензоилпероксид

Benzoyl peroxide oxidizes retinol, inactivating it. When both are needed – use at different times: BPO in morning, retinol at night.

L-Ascorbic Acid (Vitamin C)L-Аскорбиновая кислота (витамин C)

Different optimal pH: retinoids need neutral, vitamin C needs acidic. Use at different times: C in morning, retinol at night.
