Keratosis Pilaris is a very common disorder in which small red or skin-colored bumps occur in hair follicles or pores, often with some redness around the pore. The affected skin is typically dry and patchy as well.
It occurs in about 60% of teens and is more commonly seen in girls. The majority of people with keratosis pilaris see it on the upper arms. Over half have some involvement on their upper thighs and about 30% have some involvement on their buttocks. About 40% of adults will get it in varying degrees. It is more common in those with atopic conditions (asthma, hay fever, eczema), ichthyosis vulgaris, hypothyrodism, Cushing’s disease and a number of rare genetic conditions. Keratosis pilaris isn’t a serious medical concern and will often lessen on its own.
