Can nicotinamide be used after glycolic acid?
I have heard from many physicians. The method of skin care and the order of medication are related to the effect and skin safety. Today there is doubt that nicotinamide can be used after glycolic acid?

The two are used alone, and each has its own function. When used in combination, it must be considered carefully. After the use of glycolic acid, the stratum corneum of the skin becomes thinner or sensitive. If nicotinamide is applied at this time, it is also irritating to a certain extent, or it may increase the burden on the skin, and the discomfort is even worse.

If the skin is not red, swollen, itchy, etc., the scope of use can be gradually expanded. And after using glycolic acid, it is appropriate to wait for the skin to feel better, and then use nicotinamide, during which or every

In short, nicotinamide can be used after glycolic acid, but it must be tolerated by the skin, step by step, in order to achieve the effect of maintenance and ensure skin health.
