On the Compatibility of Glycolic Acid and Retinol
Fuglycolic Acid and Retinol are both ingredients used in skin care. However, whether the two can be mixed is a matter of doubt.

Glycolic Acid, a fruit acid or the like, has the ability to exfoliate, can make the old keratin on the surface of the skin fall off, make the skin smoother and more delicate, and can promote skin metabolism and increase its luster. Retinol, also known as vitamin A alcohol, can promote the production of collagen, improve skin texture, reduce wrinkles, and have a good effect on skin anti-aging.

However, mixing the two requires caution. Glycolic acid is acidic, and retinol has poor stability in an acidic environment. Mixing the two may cause retinol inactivation and reduce its skin care effect. And both glycolic acid and retinol are irritating to the skin. If used in combination, it may cause skin discomfort such as redness, tingling, itching, etc.

Therefore, if you want to use glycolic acid and retinol, you can use them in time, use glycolic acid products during the day and retinol products at night to buffer the skin; or try them on a small area of skin first to see if they have adverse reactions, and then decide whether to mix them. In this way, you can enjoy the benefits of both skin care and avoid skin damage.
