Hi. Greetings. Please note : Acne is a common problem at your age. Milk - excessive consumption can worsen acne. Reduce intake of chocolates and junk food too. Use a topical retinoid cream daily night. You may need a short course of antibiotics since you are looking for early improvement. Discuss other suitable forms of treatment with your dermatologist or send further queries on follow up chat. Hope this helps. Warm regards.
