Kans is nothing more than hydrating, and there is no limit to the ingredients that are more or less medicinal. In other words, drugs are three points poisonous.

On the contrary, people who don't use cosmetics much will get quick results with everything. What does this mean? Welcome to scan my avatar and communicate with me, or look at my signature name.
