What is acne?
Acne affects hair follicles and oil glands. It is common in adolescence but can continue into adulthood and does not mean poor hygiene.
Causes, symptoms and diagnosis
1. Definition and causes Oil production, blocked follicles and inflammation contribute. Hormones and some medicines may play roles; one food is not the cause in everyone. 2. Symptoms and assessment Blackheads, whiteheads, inflamed spots or deep painful nodules may affect face, back and chest. Examination assesses type and scarring risk. 3. Care and treatment Gentle cleansing, topical treatments or oral medicines may be used. Some drugs have serious pregnancy restrictions, requiring clinical guidance and monitoring.
Warning signs and prevention
4. When to seek help Painful deep lesions, scarring, significant distress or poor response merit dermatology care. Squeezing can worsen inflammation and scarring. 5. Prevention and daily life Non-irritating skin care and following instructions help. Improvement often takes weeks; instant-cure claims deserve caution.
