hello and welcome to healthcare magic.
i agree with Dr Rakesh, what you can do is first of all avoid oily foods,spicy foods.
make sure you dont use anything and everything you get in the market.you can try topical vit a preparations but make sure you apply it the right way like small dots on the pimples
dont apply it like a moisturiser.there are a few procedures done for acne
which you can try if it is too extensive which your dermatologist
will guide you.
