Get this... I have milia and keratosis pilaris!! ARG... so my forehead is all bumpy, and so are the backs of my arms.
However, there is treatment. Milia, it seems, is easier to get rid of. For milia, I just use steam and a washcloth, and I do this daily... soak the end of a washcloth in very hot water, and then wipe along the forehead. Basically, it's a mild dermabrasion without damaging the skin. Just to remove the bumps and prevent new ones from forming. I also use an AHA cleanser which helps a whole lot.
And that leads into the topic... keratosis pilaris has no known cure, but I have noticed that using AHA and BHA solutions really help. I shower with a cleanser containing salicylic acid (BHA) and concentrate on buffing those areas with a washcloth. Then I use an AHA lotion (AquaGlycolic hand and body lotion) to moisturize while removing the dead skin cells. This seems to keep the problem down to a minimum, and I've noticed fast improvements over the past two weeks.
If you can't afford AquaGlycolic, just buy a bottle of Apple Cider Vinegar--nature's miracle cure. It's a powerful AHA (people with sensitive skin generally dillute it). It also has antibacterial and antibiotic properties. There are only two side effects when using apple cider vinegar: red skin and the smell. For me, the smell is nice, a slightly bitter apple smell. For many other people, it's an awful odor. However, inhaling the fumes of apple cider can help prevent bronchial infections. After applying apple cider vinegar to the skin, it generally turns it bright red--due not to irritation, but to the opening of capillaries and blood vessels under the skin. This creates an almost sunburn-like redness that goes away after thirty minutes or so. I only use this stuff at night before bedtime, as a result.
