Acne is one of the most common skin conditions, affecting millions of people worldwide, particularly adolescents and young adults. Characterized by the appearance of pimples, blackheads, and cysts, acne primarily occurs on the face, chest, back, and shoulders. While acne is often associated with puberty, it can occur at any age and can range from mild to severe.
Causes of Acne
Acne is primarily caused by the overproduction of oil (sebum) in the skin, which can clog hair follicles. This leads to the growth of bacteria and the formation of pimples. Hormonal changes, especially during puberty, menstruation, or pregnancy, can increase oil production, making acne more likely. Other factors such as stress, diet, certain medications, and genetic predisposition can also contribute to the development of acne.
