However, many studies and practices in recent years have shown that if the product formula is scientific, the process is excellent, and the two are compatible, good results can also be obtained. The key is to control the pH value of the product, so that it is in an appropriate range, and to ensure that the concentration of the two is reasonable. In this way, not only can the effects of both can be achieved, the keratin renewal of glycolic acid helps nicotinamide to better play the equivalent properties of whitening and repair, but nicotinamide can also relieve the irritation caused by glycolic acid to a certain extent, synergistically enhance the effect, and bring more comprehensive care to the skin.
