Hey, so I,ve been dealing with light acne since Im 14, Im 19 now and decided to go to the dermatologist about a month ago to just get over with acne and some little red marks, since I moved to a new city I had a really really bad breakout, like never before, so she prescribed me doxycycline 100 mg once a day and Retin A 0.025% every night, and sunblock every timeI go out...so far I have not seen any improvements, my acne just got worse (maybe it is retin-a purge? since Im starting week 4) I have never developed scarring until I started with the treatment. I'm not completely sure if it is scarring or PIE / PIH, cause I see holes for sure, but I dont know if it is a scarring, post acne wounding, if someone would please help me i would greatly aprreciate it.
