Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have acne which is mainly due to clogging of skin pores, stress and dehydration. I would suggest you to avoid exposure to oily, greasy and sharp food substances. Apply clindamycin gel as well. Apply cotton dipped in tea tree oil and apply them on scars. Drink plenty of water. As doctor advised you to use retin-A gel and tetralysal pills you should use retin-A gel at night and take tetralysal pills one daily. Apply bio oil for 30 mins daily. Don t use any cosmetics and hard substances on face. Apply vitamin E oil at night. Visit dermatologist once and get it examined and go for micro-peeling and dermabrasion. You can apply aloe vera gel on them as well. Wash your skin 2-3 times a day with mild soap and warm water to prevent the accumulation of oil ,dust and bacteria on your skin.Take diet rich in vitamin E. Hope your concern has been resolved. Get Well soon. Best Wishes, Dr. Harry Maheshwari
