Thanks for writing here.Acne
is age related problem.
Treatment is prolonged and you need to continue with it.
In early phase it can even aggravate the condition.
Treatment which you are receiving is correct and you need to continue with it.
Keep faith on your doctor.
Do not try to squeeze lesions.
Do not apply any oily sunscreens or other creams.
Take sun protection as far as possible.
Hope this help you.Take care.
