Reduced Brown Spots – Inhibits melanin production, which prevents new dark spots from forming. By increasing cell turnover, it stimulates new, healthy cells to be produced, revealing a clear, even skin tone.

Reduced Acne and Clearer Skin – It has anti-bacterial and anti-inflammatory properties that reduce and prevent acne. It also can have a mattifying effect on the skin.

Smooth Skin Texture – It is formulated with 3 Alpha Hydroxy Acids, which gently slough away dry, dead skin cells to reveal smooth healthy skin.
