Lactic acid is a naturally occurring alpha-hydroxy acid (AHA) found in sour milk. In skincare, it helps gently lift away dull, built-up surface cells to reveal skin that feels smoother, softer and fresher-looking.

Historically, Queen Cleopatra is said to have bathed in sour milk to enhance the look and feel of her skin — a beauty ritual now understood to be linked to the natural Lactic acid it contains.
