Have you thought why you have dark underarms? Have you tried cleaning it to the max to make it as white as celebrities’ underarms? Maybe you have used your loofah and scrubbed away? Would it surprise you if scrubbing with your loofah actually makes your underarms darker? Rubbing your underarms too hard with your loofah or frequent shaving will cause dark underarms. To have a whiter underarm, it is suggested to purchase a brightening deodorant. A bleaching cream spiked with kojic acid and hydroquinone will also do the trick for those dark armpits. A word of caution, if all of these whitening stuffs irritate your underarms because of chemicals, better see your dermatologist.
