What is a skin condition that starts with a?

A skin condition that starts with "A" is acne, which is characterized by the presence of pimples, blackheads, and cysts primarily on the face, back, and shoulders. It occurs when hair follicles become clogged with oil and dead skin cells, often influenced by hormonal changes. Acne is common among teenagers but can affect individuals of all ages. Treatment options include topical medications, oral antibiotics, and lifestyle changes.
