Oh yes, bleaching is not good for the human skin. In spite of how those that use it see it, it is wrong for them to trail the path of using chemicals to wash their skins. Unfortunately, bleaching has long been in practice for quite sometime now, although it wasn't popular back then than as it is now.
Basically, what bleaching does to the skin is to erode the melanin, which is the pigment that gives the skin its natural colour. And the continuous use of it would not only remove this pigment, but also wash off the dermal cells protecting the skin against pathogens, thereby making the skin to be prone to all kinds of infections. Sadly, bleaching of the skin can cause serious incurable skin disease such as cancer of the skin.
Bleaching is terribly bad for the skin, therefore it is not ideal for anyone to be into it.
