Part of the Alpha Hydroxy Acid family, Lactic Acid is found in milk that has soured or fermented. It has many skin benefits and is one of the most versatile ingredients used in skin care products; it exfoliates, hydrates, is antibacterial and boosts collagen production in the skin. It is milder than other acids and it doesn’t cause irritation or allergic reactions. This makes it a popular ingredient in both anti-aging and acne treatments.
It is great for people who suffer with acne, rosacea, wrinkles and sensitive skin, however if you are pregnant you should avoid products that contain Lactic Acid, as it can contaminate breast milk.
