hi
Welcome to Healthcare Magic Forum
you are suffering from a very common problem namely 
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 moisturisers 
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 
You might need to apply some antiacne medications like Clindamycin gel over the affected area.
In case the topical therapy alone does not help you, you should get yourself assessed by the 
dermatologist since you might need treatment with oral anti acne agents.
Hope it helps 
Wishing you speedy recovery
