Lactic Acid
INCI: Lactic Acid
What It Is
Lactic acid is a mild, water-soluble alpha hydroxy acid (AHA) that helps exfoliate the skin’s surface by gently breaking down dead skin cells. Naturally found in fermented foods, it is known for brightening the complexion while supporting hydration.
Why We Use It
We use lactic acid to promote smoother, more even-toned skin without the harshness of stronger acids. At low concentrations, it helps maintain a healthy pH, gently exfoliates, and improves moisture retention—making it suitable even for sensitive skin.
Origin & How It’s Made
Lactic acid is sourced through the fermentation of plant-derived sugars, such as glucose from corn or beets. This natural fermentation process produces a bioavailable form of lactic acid that is then purified for safe cosmetic use.
