dark under arm

Hello Whyllam. You can prevent having dark underarms by using whitening deodorants, and by avoiding shaving your underarms. It's always better to wax so you can get to the roots of your underarm hear which is responsible for leaving a black shade we don't like. It won't happen during the first time you wax but after three to five sessions you'll be surprised of the difference! In my case waxing regularly has kept me from developing dark underarms. Regards!
