I’ve had this six years, started on my upper back, slowly crept its way down and came to my shoulders and chest for a bit. Continued to spread downwards. It got really bad from when I was in highschool and they gave me P.E first block, didn’t let us use showers so we were told to use baby wipes. And i’d go the rest of the day with out showering after a serious sweat in the Miami sun lol. Acne has lightened up a lot since but isn’t cured, persistent blackheads, and persistent scars is what I have
