So, I have had these chest 'acne' bumps for a long time. Each one grows and stays, not a single one had receeded, at firs they look like normal chest acne, then they grow bigger and bigger, very slowly. Had them for at least 2 years now on chest and back. Face is clear of acne (mostly)
the acne is permanent, never receeds, but are never painful, even when squeezed, no itch, nothing, but they are red.
