The most common Alpha Hydroxy Acids (AHAs) used in skincare include Glycolic Acid (derived from sugar cane), Lactic Acid (obtained from sour milk), Citric Acid (extracted from citrus fruits), and Malic Acid (derived from apples). These water-soluble acids are renowned for their efficiency as exfoliators.
Glycolic Acid:
Glycolic Acid, derived from sugar cane, boasts the smallest molecules among all AHAs, enabling it to penetrate deeply into the skin. In both solid and soluble forms, it is colorless. This AHA strengthens the deeper layers of the skin, promoting exfoliation for a brighter complexion. Widely recognized for its anti-aging properties, The Ordinary 7% Glycolic Acid serum is a highly recommended product
Lactic Acid:
Obtained from sour milk, Lactic Acid has larger molecules compared to glycolic acid but is smaller than fruit-derived AHAs. In solid form, it appears white and becomes colorless when dissolved. This AHA primarily exfoliates the top layer of the skin. In higher concentrations, it contributes to thicker, firmer skin, diminishing the appearance of fine lines and wrinkles. Ideal for moisturizing, The Ordinary Lactic Acid 10% is a recommended option.
Citric Acid:
Derived from citric fruits, Citric Acid possesses large molecules and is colorless. Functioning as an exfoliator, it aids in addressing photoaging, improving skin elasticity, firmness, and smoothing the skin's top layer.
Malic Acid:
Derived from apples and cherries, Malic Acid is colorless. As an exfoliator, it enhances skin texture and addresses the appearance of fine lines and wrinkles.
When purchasing AHAs, it is advisable to start with lower concentrations and gradually increase the percentage based on the skin's tolerance. For more personalized information, consider booking a consultation with LAP.
