I had dark underarms ever since I reached puberty. I was awkward and couldnt wear what I wanted too. I tried out bleaching creams, whitening deodorants, etc. But none helped. It even made my UA worse.
I grew tired 2 years ago and said, BLAH! blah with dark UA, Ill just settle with something simple and so I grabbed the stick looking deodorant at Watson's since it was cheap and simple (pure alum chloride) and it said in the back it didnt stain clothes so triple yay!
