To remove dark patches from your underarms (which occur for some people when they remove the underarm hair and make them really upset about it), all you got to do is rub a slice of tomato vigorously on the area of the patch.
Leave it on overnight.
You may have to do this twice a day depending on how dark the patch is.
During the day you may leave it on for 1 hour.
It helps to cleanse out the dark skin and shrink the pores.
