Am having black spots on face,which is the outcome of pimplesand my skin is oily.so *** suggest me how to remove these spots from my face

Blackheads are just dirt in large oily pores, so splash tons of warm water on your face and then scrub with soap and tons more water, once a day. There are special scrubbers and there are antiseptic pads for pimples, but you can just use a mild unscented soap and rinse well.
