There are several conditions that cause the skin to become rough and flakey. A few of the most common of these are keratosis pilaris, actinic keratoses, folliculitis and eczema. Keratosis pilaris is a condition where small bumps appear on the skin usually around the thighs, arms, cheeks, and buttocks. This condition is caused by an overproduction of keratin, which blocks the hair follicles and causes bumps to form. The bumps don’t hurt or itch and the condition is harmless but some people are troubled by the appearance and seek treatment for cosmetic reasons. Actinic keratoses is also known as solar keratosis and is a scaly growth brought on by sun damage or exposure to UV radiation. It is considered a pre-cancer so it is important to seek treatment as soon as they appear. Folliculitis manifests as small, white-headed pimples around the hair follicles. It is sometimes caused by shaving or use of topical steroid creams. It is also common among acne sufferers. Folliculitis blemishes can be painful or itchy and can either clear up on their own or lead to permanent scarring. Eczema usually begins during childhood and is known to be a hereditary condition. It generally appears as a rash on the arms and behind the knees, but can appear anywhere on the body, including the face.
