Never put bleach on your skin. You shouldn't put alcohol on your pimples either it will dry your skin and remove all natural oils. This will cause a massive case of dry skin and will cause wrinkles at a very young age.
No..its very dangerous for your skin. If you're trying to ligthen your skin or get rid of a scar or something, there are creams for that, go to the pharmacy. Bleach will irritate your skin, especially your face where it's more sensitive, you might break out even more or start peeling.
