Goodday! I just want to ask some simple steps or solutions on how to whiten black underarm.
Thanks!

A peeling solution is used to remove the outer layer of the skin. After the peeling is done, you need to put bleaching agents for applying every night at home.

Another treatment is armpit bleaching. Some people go straight to this treatment, but it is strongly recommended by dermatologists that one has to undergo peeling first before the bleaching.

If you want an inexpensive natural whitening agent, use lemons.
