What are the complications of cystic acne?

Opening up acne cysts — by popping or picking them — increases the risk of scarring and bacterial skin infections like cellulitis.

Some people develop pigment changes (light or dark) spots at the site of the acne cyst after the skin clears up. These spots may be pink, purple, red, black or brown. They eventually fade away, but it may take more than a year.
