Keratosis pilaris is a common, harmless skin condition that causes dry, rough patches and tiny bumps, often on the upper arms, thighs, cheeks or buttocks.
Cause of keratosis pilaris
- Keratosis pilaris is caused by the buildup of keratin.
- The keratin blocks the opening of hair follicles, causing patches of rough, bumpy skin.
- It may occur in association with a genetic disease or with skin conditions such as atopic dermatitis.
Treatment for keratosis pilaris
- Creams to remove dead skin cells. Creams containing alpha hydroxy acid, lactic acid, salicylic acid or urea.
- Creams to prevent plugged follicles. Creams derived from vitamin A (topical retinoids).
