Acne vulgaris is a common skin condition that primarily affects teenagers and young adults, though it can occur at any age. It is characterized by the presence of pimples, blackheads, and cysts, which develop when hair follicles become clogged with oil and dead skin cells. Hormonal changes, particularly during puberty, can increase oil production, leading to outbreaks. The condition can be influenced by various factors, including genetics, diet, and stress. While acne vulgaris is not harmful, it can cause emotional distress and may lead to scarring if not treated properly. Various treatments, including topical medications and lifestyle changes, can help manage symptoms.
