Exfoliant ingredient
Tartaric Acid
A naturally occurring alpha-hydroxy acid (AHA) found in grapes and wine, used in cosmetics for its mild exfoliating, pH-buffering, and antioxidant properties; gentler than glycolic acid due to its larger molecular size and slower skin penetration.
Also known as: l-tartaric acid, grape acid, 2,3-dihydroxybutanedioic acid

Benefits
- ✓AHA exfoliant derived primarily from grapes and wine; loosens dead skin cells to improve texture and tone
- ✓Larger molecular size than glycolic or malic acid results in slower, more superficial penetration — gentler exfoliation profile
- ✓Contributes to pH stabilization in formulations, enhancing the effectiveness of other AHAs
- ✓Antioxidant activity supports skin's defense against free-radical damage
- ✓Can help brighten skin and reduce the appearance of uneven pigmentation with regular use
Watch for
- ⚠At high concentrations may cause irritation, stinging, or adverse reactions like other AHAs
- ⚠Increases photosensitivity; daily SPF use recommended when using exfoliant-containing products
- ⚠Not suitable for compromised or sensitized skin at active exfoliant concentrations
