My underarms are little dark bcoz of hair remover used 10-20 times but as i see darknes i stopped using it from 4 5yrs what to do to make it fairer?

Bleaching cream: The underarms can get darker from irritation from hair removal, depilatories, waxing, shaving. Bleaching creams may help temporarily but discolorations will continue to worsen if you continue to use the above methods. Laser hair removal is a longer term solution that would help by eliminating hairs so you would not have to do daily treatments that irritate the skin causing discoloration.
