What is shiny? Is it harmful to human body?

You don't have to tell me. Enter the skin and wait for chronic poisoning. Those things should be whitening agents or something. Don't many people use it just to look good? However, it ignores substances that are harmful to the skin. Why do many people often use certain cosmetics and skin care products for a period of time, but their skin is allergic? There are still many people whose skin turns black after using it for a while. It is these substances that play this role. Good thing you found out. Congratulations. Good luck.
