Keratosis pilaris is a common skin condition characterized by rough, bumpy skin most often found on the back of the arms, thighs, and cheeks. It is a common finding in those with dry and sensitive skin. It typically affects children and teenagers and can improve or resolve over time. The condition is harmless and does not necessitate treatment. If bothersome, the use of a good moisturizer and over-the-counter or prescription topical medications can help improve the condition.
