Can you use Boric Acid to get rid of underarm discolouration?
definately not I have the same problem and what worked for me was to take a little bit of baking soda you know the same kind you use to freshen up your fridge and mix it with water to make a paste rub that on your underarms and then rinse it worked for me and I was shocked so you should try that. It keeps it from looking dark for quite a while also.
