Bumpy underarms?

Ingrown hairs are to blame for this. And to make matters worse, they can leave dark spots as they heal. To prevent it, experts recommend using a roll-on deodorant that contains urea and salicylic acid. This will help soften hair and keep underarm skin exfoliated. It will also be best to shave at the end of your shower, when hair is softer, so the freshly shaved hairs will be less likely to poke your skin.
