Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It often appears as pimples, blackheads, or cysts, primarily on the face, back, and shoulders. Hormonal changes, stress, and certain medications can trigger or worsen acne, making it a concern for many, especially teenagers. While acne is not dangerous, it can affect self-esteem and lead to scarring if not treated properly. Over-the-counter treatments, such as benzoyl peroxide and salicylic acid, are often effective. In more severe cases, a dermatologist may recommend prescription medications or therapies to help manage the condition.
