Even after you've successfully removed a tough pimple, a scar may remain as an unsightly reminder. These scars develop when the dermis (underlying skin tissue), usually as a result of picking at or bursting a pimple, is injured. Although acne scars may not be as physically uncomfortable as acne itself, they can lower one's self-esteem and last for years. Finding the most effective kind of treatment can help you get rid of those bothersome pigmentations as soon as feasible.
