Keratosis pilaris is condition that develops because of a similar process that occurs with acne; mainly cells that clump together in terminal hair follicles. It may be found on the upper arms and sometimes on the thighs, cheeks, or scalp. It appears as sandpaper-like grainy bumps and, in some cases, as large impactions, becoming inflamed and tender. It is believed that keratosis pilaris is frequently accompanied by acne. Therefore, keratosis pilaris responds well to keratolytic agents, such as glycolic or salicylic acid, much in the same way as does acne. Dr. Hubbell has been treating patients with painful skin conditions like this for many years. Choose a board certified dermatologist to help with your Keratosis Pilaris.
