Keratosis pilaris is a very common condition that causes tiny rough bumps on your skin. The condition is usually accompanied by dry or rough skin.
Its common amongst young children, though it can occur at any age. Generally, the upper arms, thighs, cheeks, and buttocks are affected. The condition may not cause itchiness but may worsen with cold or dry weather conditions.
Keratosis pilaris is caused by excess keratin in the skin. Keratin is a protein in the skin that helps protect it from infections. With excess keratin, the opening of hair follicles gets blocked with scaly plugs.
Though the condition is harmless, most often considered a variant of normal skin, and usually corrects itself with age, most prefer an improvement in appearance.
