what are the tips to help me whiten my underarm and to prevent from body odor? During my high school days I've experienced an allergy on my underarm and it becomes reddish to darker color and it's really hard for me to whiten my underarm and there is also bad odor due to excessive sweating. What i'm gonna do?

for the sweating try nivea deodorant,DRY confidence 24 hour,deo compact its in avery small thin pump action bottle great for handbag or even poket,i had same problem with sweating till last week and it did smell bad i was changing my top every 2 or 3 hours,untill i seen the nivea in tesco its great it really is.
or you can go to your doctor and get Anhydrol Forte but the directions are stupid,it says you shouldnt shave 12 hours before or after use,its for underarms,hands and feet.and you can get it on clothes,rings,ect and you cant take it out with you the bottle has to be upright all the time.i decided to stick with the nivea it smells nice and im dry all day my wash load has gone down by more than half lol

THANK GOD FOR NIVEA DRY CONFIDENCE

LOL

As far as whitening them, usually a dermatologist can give you something for that. I've tried scrubs and a ton of different things. For whitening it'd have to be the skin guy. Because it's more than just having dark underarms. It's actually a bacteria or something which causes it and the only way to get rid of it is by gettin' to the doctor. They said that it isn't harmful, but just a pain if you want white pits! :) I read an article in a magazine a long time ago.
