22 year old male here. I've dealt with bad acne since puberty. After graduating college and several months on the acne.org regimen, my face has miraculously cleared of active infections. However, the raised bumps on my nose still remain. Whenever I broke out on my nose, usually a finger-tip sized red area would appear and would be painful to touch. Usually it'd become raised, and then burst and turn dark red for a while before subsiding.

Does anybody know if this is hypotrophic scarring? Sebaceous hyperplasia? And what kind of treatment would be best to get rid of these stubborn rascals? When my nose turns red from cold weather, the bumps usually remain less red than the rest of the nose.
