You Asked: Should I Worry About These Bumps on My Arm?

You're asking and I'm answering.

Dear Fit,
I've noticed these tiny reddish bumps on the backs of my arms. They don't hurt or anything, but I'm embarrassed because they look and feel so gross. Any idea what it is? I don't think it's acne because my face has always been pretty clear. Whatever it is, how can I get rid of it? Please help since I want to wear tank tops without worry about these darn bumps.

It sounds like those bumps are making you self conscious, and when it comes to conditions of the skin, I do always think it best to visit a dermatologist. However, your bumps look like a common skin condition known keratosis pilaris, sometimes referred to as "chicken skin." This condition is quite common; about 50 percent of the entire population have this type of bumpy skin.

If those bumps are indeed keratosis pilaris, I have some suggestions and an explanation of the causes so just read more.

Normally as you go about your day, your dead skin cells are supposed to just flake off. With this condition though, those dead skin cells plug up your hair follicles. The bumps look like tiny red or white pimples, and they have a dry, sandpaper feel. Even though they shouldn't hurt or itch, they can understandably make you feel self-conscious about baring your skin.

If your arm bumps are in fact keratosis pilaris, using a good moisturizer on the area twice a day that contains salicylic acid, urea, or alphahydroxy can be an effective treatment. Taking hot showers, allowing your skin soak up the water a little, and then gently exfoliate using loofah gloves is also a great trick for keeping the bumps at bay. A dermatologist can also prescribe a topical retinoid cream (made from vitamin A), which may help promote cell turnover and prevent the hair follicles from getting plugged in the first place. Whatever you do, I'm sorry to say that it takes continuous effort and maintenance in order to keep your skin free of these bumps.
