When matching skin care ingredients, people often wonder whether polyhydroxy acids (PHA) can be used together with glycolic acid. As a new generation of fruit acids, PHA is relatively mild in nature and has moisturizing, antioxidant and other effects. It can help the skin lock in moisture and improve the dryness and roughness of the skin. Glycolic acid is a relatively common and relatively strong fruit acid. It can effectively remove the aging stratum corneum on the surface of the skin, promote the renewal of skin cells, make the skin smoother and more delicate, and also have a certain improvement effect on acne, acne and other problems.

However, using PHA together with glycolic acid is not without risk. Due to the relatively large irritation of glycolic acid, if mixed with PHA, it may superimpose the irritation suffered by the skin. For people with more sensitive skin, this is very likely to cause skin discomfort, such as redness, tingling, itching and other symptoms. Even if the skin is well tolerated, improper use of this combination for a long time may also lead to damage to the skin barrier, making the skin fragile and more susceptible to the influence of the external environment.

If you want to try to use PHA with glycolic acid, you must proceed with caution. First, it is recommended to try it on a small area of skin first, and observe it for 24 to 48 hours to see if there are any adverse reactions. If there is no abnormality in the skin, then gradually expand the scope of use. Secondly, the frequency of use should be strictly controlled. You can use it 1 to 2 times a week at the beginning. After the skin adapts, you can increase the number of uses according to the actual situation, but it should not be too frequent Furthermore, it is necessary to strengthen the moisturizing and sun protection of the skin during use. Because these two ingredients promote keratin renewal and make the skin more sensitive to ultraviolet rays, good sun protection can effectively avoid skin damage, and adequate moisturizing can help maintain the health of the skin. In short, the combination of PHA and glycolic acid can be used reasonably and cautiously to maximize the protection of skin health while pursuing skin beauty effects.
