Keratosis pilaris (KP) is a common skin condition that causes small, rough, white or reddish bumps or patches on the skin. It is also known as "chicken skin" because it looks like goosebumps. The bumps are caused by the buildup of keratin, a hard protein that protects skin from harmful substances and infection, which blocks the opening of hair follicles. KP is a benign condition that usually appears on the upper arms, thighs, cheeks, or buttocks. It can occur at any age, but its more common in young children and adolescents. The bumps usually dont hurt or itch, but the skin can sometimes feel itchy and irritable. KP can worsen when seasonal changes cause low humidity and dry skin.

KP cannot be cured or prevented, but it can be treated with moisturizers and prescription creams to help improve how the skin looks. Moisturizers with ammonium lactate and alpha hydroxyl acids, such as AmLactin® or CeraVe SA® cream, are the best choices for rough, bumpy skin and people with KP. Other treatments include steroid creams and laser treatments. It is important to avoid friction from tight clothes and protect affected areas from excessive sun exposure.

KP is often a mild condition that doesnt require medical treatment and usually disappears by the age of 30. However, if symptoms are causing anxiety or discomfort, it is recommended to consult a healthcare provider or a specialist in skin conditions (dermatologist).
