Hello Thanks for the query. Don t worry acne is common in this age group and will go with age. It is very important to know the cause of acne in order to approach it properly. Following are the common causes. 1. Blocked glands of face 2. Bacterial infection. 3. Excess Oil production by glands. 4. Environmental pollution. It is better to go for a combined approach to get rid of acne completely. Please follow the following. 1. Use a combination of adapalene or other retinoid cream and clindamycin. This will take care of blockade as well as bacterial infection 2. Use a water based sunscreen with spf 30. 3. Use a drying face wash like tea tree oil. 4. Its best to keep face covered by cloth whenever possible to protect from dirt. 5. Don’t rupture or try to remove scabs from infected acne, This will lead to pigmentation and scar formation. Don’t apply steroid creams, they give immediate relief but later cause damage. Let me know if you have any other doubts. Thank you.
