It sounds like something I had on my upper arms as a teen. It's probably not acne though... it just sort of looks like white heads and is yucky and bumpy. I lived with it for years before it seemed to go away. I found the following info on web md. Hope this is helpful!!
Keratosis Pilaris
Keratosis pilaris (commonly called KP) appears as "chicken skin bumps" on the skin. These bumps usually appear on the upper arms and thighs. They also can appear on the cheeks, back and buttocks. Keratosis pilaris, while unattractive, is harmless.
What Are the Symptoms of Keratosis Pilaris?
This disorder appears as small, rough bumps. The bumps are usually white or red, but do not itch or hurt. Keratosis pilaris is usually worse during the winter months or other times of low humidity when skin becomes dry. It also may worsen during pregnancy or after childbirth.
How Is Keratosis Pilaris Treated?
Although the condition may remain for years, it gradually disappears before age 30 in most cases. Treatment of keratosis pilaris is not medically necessary; but, individuals with this condition may want to seek treatment for cosmetic reasons.
The initial treatment of keratosis pilaris should be intensive moisturizing. A cream such as Acid Mantle, Vaseline or Complex 15 can be applied after bathing, and then re-applied several times a day. Other treatments may include:
Medicated creams containing urea (Carmol-20) or alpha-hydroxy acids (Aqua Glycolic, Lacticare) applied twice daily
Efforts to unplug pores by taking long, hot soaking tub baths and then rubbing the areas with a coarse washcloth or stiff brush
........
I would totally recommend using heavy moisturizers and switching to a soap free body wash like Olay. Soaps tend to dry out the skin more and make it worse. OH... and if you rub the spots too hard they just tend to get sort of scabby looking.... ewww.
Good luck!!
