hi 
You seem to have developed 
acne . 
Before coming to the exact treatment, I would like you to follow certain precautions: 
1. Avoid using any oily creams or lotions over face as much as possible. 
You can however use oil free moisturizers. 
2. Wash your face frequently inorder to keep it dry .
3. Drink plenty of water .     
4. Try to avoid eating dry fruits. 
5.Avoid touching or squeezing of 
pimples. 
6. Avoid Hair oil .
7. Always use a sunscreen (SPF> 26) when going out in the sun. 
Now as far as your condition is concerned, I would advise you might need to apply some antiacne medications like 
Clindamycin gel over the affected area twice a day. 
You might need a systemic agent also to control acne ,so if the above medicines do not help you much, then see a 
dermatologist for the same.
Hope it helps
