I have lot of pimple.in my face and my skin is very much oily so please tell me what to do.

Question

Be patient. Acne improves slowly even with the most powerful treatments from your doctor. Do not expect much improvement in the first few weeks of any treatment.
Do not pick! Discipline yourself not to pick your spots, as this may encourage scarring. 
Wash carefully. Wash the affected area twice a day with a pH-balanced, unperfumed soap. Avoid facial scrubs and abrasive cleansers, which might increase the inflammation of the skin and make scarring more likely.
Avoid heavy and greasy make-up. Oil-free make-up is available in some ranges. Remove it at night with a gentle cleanser before washing. If your acne is all over your face, with lots of blackheads, your make-up might be aggravating the problem, so consider different brands. To disguise an individual spot, use a medicated spot concealer stick or cream a couple of shades lighter than your normal skin tone to counteract any redness. Apply it with a tiny brush to just cover the spot, removing any excess by tapping the area gently with your finger. Do not apply it to a large area or you may make the skin sensitive.
Consider a zinc supplement.  
Chemical peels can be helpful in some cases of acne with many blocked pores,oily skin and for acne scars.

It is important to seek professional advice if you are considering trying a chemical peel to avoid side effects.
