Comedo (blackhead and whitehead) extraction by a board-certified dermatologist is generally safe and should not leave scars if done correctly. The dermatologists use a metal tool called comedo extractor that puts gentle pressure around the blackhead pushing it upwards without damage to the surrounding skin. That being said professional extraction should always be used as a supplement to an effective topical acne treatment system.
