When it comes to which azelaic acid and glycolic acid to use first, the knowledge is quite deep. The quality of the husband's skin varies from person to person, and this is the first consideration. If the skin is more sensitive and weak, it seems to take azelaic acid first. Azelaic acid is mild in nature, has antibacterial and anti-inflammatory properties, and can slow down pigmentation. It is quite friendly to sensitive and weak skin. When it is first used, the skin is also easy to adapt.

However, if the skin is well tolerated and wants a faster skin rejuvenation effect, glycolic acid may be the best choice. Glycolic acid is a fruit acid, which can effectively exfoliate, promote skin metabolism, and make the skin smoother and more delicate and radiant. However, because of its strong activity, when using it for the first time, there may be a short-term tingling sensation, so it needs to be started at a low concentration and used gradually.

When using it, pay attention to the dosage and frequency. At the beginning, or every few days, when the skin adapts, the frequency should be gradually increased. And before and after use, it must be properly moisturized to prevent dry skin. In this way, choose carefully according to your own skin characteristics and use it reasonably to achieve the best skin care effect.
