Hi, I have dark underarms and I don't know how to whiten it up.. is there any home remedy I can use? Please help... thanks a lot!

There are many factors that causes dark under arms. Some people tend to get dark under arms from friction and continuous sweating. Other factors include, natural hair growth, ingrown hairs or genetics. Try using a loofah scrub or mild scrub. It will help remove dead skin cells from the skin and help new skin cells come in. You should also use a skin lightening cream on those areas to help fade the discoloration.
