I popped a pimple and i wanna know how to get rid of the dark scar on my face?

Post inflammatory: Post inflammatory hyperpigmentation is a common and normal response during the healing process. When traumatized skin heals, redness, followed by dark discoloration often occurs. With time, the site will usually resume normal coloration to match the surrounding skin. Topical steroid creams applied initially can help reduce inflammation and prevent excessive discoloration (sparingly on the face!)
