Stop now!!!! That is all I can say. I never had acne with cysts but I became obsessed with squeezing blackheads (multiple times a day) and I can tell you, itwillcreate scars. I have deep dark scars that I'm always worried about. For nose blackheads I highly recommend pore strips (Biore for example) -- they really work well, lately I've been using them a couple times a week along with a pore-minimizing toner and I have noticed an improvement. PLUS the pore strips are JUST as satisfying as squeezing yourself and WAY better for your skin.
