Underarm nightmare

Well I have I don't know dirt under my armpits.. Its really gross...some people say its bacteria.. Others say use lemon and baking soda.. How do I use lemon and baking soda?? What do you think will help?

well its hard to know what it is without getting a good look at it. it ould just be normal stuff that clutters underneath your arm pits at the end of the day (like a ball or balls of black fluff) which isnt anything to worry about. but it might even be a fungas or something similar, caused by all the sweat and the arms rubbing against each other...but it sounds like it might just be little balls of fluff. if they are then you can just take them off with your hand

it may just be dark skin that happens for a couple of medical reasons...

I think it's only a little blackish, it's from sweating, use lemon, and you can also try
Clean & Clear, Deep Cleansing Lotion, For Sensitive Skin, it removes the dirt, grease, and the oil that some people have.
both will burn you!
hope I helped
