Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It often manifests as pimples, whiteheads, blackheads, or cysts, primarily on the face, neck, chest, back, and shoulders. Acne can be mild, moderate, or severe and may cause emotional distress and discomfort, especially when it occurs during adolescence.
Acne scarring refers to the marks and indentations left on the skin after severe or prolonged acne lesions heal. These scars can vary in appearance and may include atrophic scars, hypertrophic scars, post-inflammatory hyperpigmentation (PIH), and keloid scars.
