Acne scars are the result of inflammation of acne blemishes. The acne pore swells and a breakdown occurs in the wall of the pore. Some acne blemishes are small and the scars created are shallow and heal quickly. Sometimes the contents of blemishes spill into the surrounding tissue and cause deeper scars.

If you have a red or brownish mark on your face that you got from a bad zit, it should eventually fade. However, it may take 12 months or longer. If you’re upset about acne marks, talk to your doctor, who might have advice on what you can do.
