Features          3.60 – 3.80 pH         Alcohol-free         Silicon-free        Oil-free         Gluten-free         Nut-free         Cruelty-free         Vegan The Ordinary Lactic Acid 5% Ha brightens and exfoliates the skin while also minimizing the appearance of sun damage and discoloration. Lactic acid has a larger molecule size than glycolic acid, which means it isn't as influential on the skin, making it the perfect choice for dry and sensitive skin types. In addition, the inclusion of hyaluronic acid in the formula helps the skin maintain a good moisture level, decreasing inflammation and irritation. Apply a tiny layer before moisturizer and after toners once a day in the evening. If you've never used an acid before, start using it thrice a week and work your way up to every day.
