When it comes to the compatibility of glycolic acid and retinol
, both glycolic acid and retinol are commonly used agents for skin care. However, whether the two can be used together is of great concern to everyone.

Glycolic acid is a fruit acid and the like, which has the power of rejuvenating the skin. It can exfoliate, shed old cells on the surface of the skin, make the skin smooth and delicate again, and can promote skin metabolism and help improve the dull complexion. Retinol, derived from vitamin A, can regulate the growth and differentiation of skin cells, enhance collagen production, and has a significant effect on anti-wrinkle and firming the skin.

However, if you want to use both, you need to be cautious. Glycolic acid is acidic, which can thin the stratum corneum of the skin and enhance the permeability of the skin. Retinol itself is also irritating to the skin. Use the two together, or cause skin irritation to intensify, such as redness, swelling, tingling, desquamation and other discomfort. If the skin is already sensitive, it is more likely to cause adverse reactions.

If you insist on using it together, check the skin's tolerance first. You can try it on a small area of skin first, such as behind the ear or at the jaw, and observe it for a few hours to a day. If there is no discomfort, you can gradually expand the scope of use. And the initial frequency of use should be low, such as once a week. After the skin adapts, increase the number of times as appropriate. When using, pay special attention to skin moisturization and sun protection. Because both may make the skin more sensitive to ultraviolet rays, without proper protection, it is easy to cause sunburn and sun aging.

In short, the combination of glycolic acid and retinol may achieve better maintenance effect, but risks coexist. Users should choose carefully according to their own skin conditions to achieve the purpose of maintaining the skin and avoiding harm.
