What is lactic acid? How to use the gentle exfoliant for brighter skin
Most people will tell you that achieving brighter, healthier-looking skin starts with regular exfoliation. To do that, you have two main options: sloughing away dead skin cells manually with an exfoliating brush or scrub, or by using a chemical exfoliant.
Lactic acid falls into the latter group. You’ve likely already spotted the ingredient on the back of many of the most popular serums and moisturizers on the market — and there’s a good reason why you see it so often. According to experts, it can be an effective way to help improve the tone and texture of your skin.
