It’s a good treatment for a certain type of depressed acne scars such as those who pit on the epidermis. It never causes acne, and the breakout you see after the treatment is actually the hidden acne in your skin that comes out after the removal of the top layer of the skin. This breakout removes on its own, and all you need to do is not to touch or rub the skin. However, if you observe excess inflammation and active nodular, then discuss the matter with your dermatologist.
