What is it?

Tartaric Acid — a dicarboxylic AHA (alpha-hydroxy acid) found in grapes, tamarind, and bananas. INCI: Tartaric Acid. MW 150 Da — the largest among AHAs (glycolic 76, lactic 90, malic 134, tartaric 150). Larger MW = slower penetration = less irritation. It is part of NMF. Often used in multi-AHA peels to balance the action.

Toners, peels, and serums for sensitive skin. Effective in complex AHA formulas as a "soft ballast." Suitable for daily use at low concentrations (1–5%).

Key Benefits

✦

The mildest AHA exfoliation

Due to the largest molecular weight among AHAs, tartaric acid penetrates the slowest. Exfoliation occurs superficially and evenly without peak concentrations in deeper layers. Minimal risk of redness and irritation even with regular use.

◈

Even tone and antioxidant protection

Tartaric acid from grapes contains traces of polyphenols — natural antioxidants. It brightens uneven tone, reduces the visibility of post-acne spots. Less effective than glycolic for deep correction, but safer for long-term use.

✧

Moisturization through NMF

Like other AHAs, tartaric acid is a component of NMF. It moisturizes the stratum corneum, attracting moisture. After exfoliation, the skin better absorbs moisturizing products — enhancing the effect of subsequent care steps.
