If you’re new to chemical exfoliation, lactic acid is a good place to start. It’s not the most gentle, and it’s not the most harsh. It’s somewhere in the middle. This is determined by molecule size. It has a larger molecule size than glycolic acid, so it doesn’t penetrate as deep into the skin. This also means it’s not as effective as other AHAs.⁠ ⁠ The benefits of using lactic acid in your skincare routine are similar to other exfoliators. It helps get rid of dead skin cells and encourages new ones to form in their places. This yields benefits related to anti-aging, texture, and even acne.⁠ ⁠ Find out more in our "Ingredient Spotlight: Lactic Acid 101" article #inbio!
