Hi Dear , Welcome to HCM. Understanding your concern. As per your query your have symptoms of acne and ingrown hair which occurs when a pore in your skin gets clogged, usually with debris, bacteria and dead skin cells and causing area to be red and swollen. It could be due to hormonal change during puberty , androgen hormones stimulate more sebum to be produced and a greater amount of skin cells to proliferate. I would suggest you to exfoliate gently once or twice a day with a salicylic acid-based exfoliant. Apply benzoyl peroxide cream or gel for killing the bacteria in the pore. It could be due to hormonal change during puberty , androgen hormones stimulate more sebum to be produced and a greater amount of skin cells to proliferate. You should wash your face using a clindamycin gel with mild soap and lukewarm water. If condition doesn t improve in a week then consult dermatologist for proper diagnosis. Doctor may prescribe chemical peeling and laser therapy. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
