What is it?

Malic Acid (malic acid) — a dicarboxylic AHA (alpha-hydroxy acid) found in apples, cherries, and other fruits. INCI: Malic Acid. MW 134 Da (more than glycolic 76 or lactic 90 — thus less aggressive). Part of NMF (natural moisturizing factor of the skin). Often used in multi-AHA formulas along with glycolic, lactic, and tartaric acid for balanced exfoliation.

Toners, peels, and serums with AHA. Often used not as a single acid but in combination with other AHAs for a milder irritation profile. Effective for sensitive skin and when introducing AHA into a routine for the first time.

Key Benefits

✦

Gentle exfoliation and cell renewal

Like AHA, malic acid weakens the intercellular bonds between dead corneocytes and accelerates their shedding. Due to its higher MW, it penetrates more slowly and gently than glycolic acid. Even tone, less noticeable pores, fresher skin appearance.

◈

Hydration and NMF component

Malic acid is a natural component of NMF — it not only exfoliates but also attracts water to the stratum corneum. Its dual function allows it to be used in hydrating toners and essences without the risk of over-drying.

✧

Synergy with other AHA

In complex AHA formulas, malic acid softens the overall irritation profile. Glycolic acid penetrates the deepest, lactic acid hydrates, malic acid adds gentle surface exfoliation. The three-tier system ensures effectiveness with reduced risk of redness.
