Is it your first experience with exfoliating? Possibly it just started to clean your skin by pushing everything wrong from deeper layers of your skin. When you struggle with acne and start with new medication, method or whatever, at the beginning it gets worse before gets better. You can going through the purge, but also it can be your skin reaction to agressive exfoliating. Really hard to say. Spots are flat or filled with pus? Didyou use acids with high concentration? For the first time, you should start with lower, more gentle concentration and increase it gradually. Also, maybe you should check microneedling?Hang in there. Sorry for my english. Thats not my native language.
