Skin Lightening Creams
These are not a good idea. According to the online encyclopaedia Wikipeadia: “skin lightening and skin bleaching is a technique of making someone’s skin lighter by lowering melanin responsible for dark skin. Some chemicals in form of pills and injections are available. Some of those chemicals can be toxic and even cause a cancer.”
The risks involved are discussed in the link below to the UK National Health Service (NHS) advice on the issue.
