How can i remove black spot created by pimples from my oily face?

Scientific Rx: After inflammation, there's often temporary hyperpigmentation. You can use a quinone bleach if you have the patience, but it's more important that you acne be controlled. This is the 21st century and any physician can make almost all acne disappear using a combination of topical and sometimes systemic medications. You have a right to this. Best wishes.
