ok so i have had acne before, when i was a freshmen it was severe and during my sophomore year i was clear but not completely. my skin completely cleared during my junior year, but there was one point where i was getting a few pimples on my chin, and i kinda went crazy and switched up my entire routine, which was dumb i know. i went on like this and switched my entire routine for 2-3 months and everything just kept getting worse. i am now back at my current routine which keeps my acne somewhat under control but its still bad. and everything i try just makes it worse. i have tried the indian healing clay which broke me out more, even after sticking through it for a while. i tried rose water and witch hazel which made it worse. i have tried ACV as a toner which didnt work. as a drink it made my acne worse. i even tried taking vitamin D, made it worse. i tried aloe vera in order to control my scarring and redness, and yes i took the one straight from the plant and it made it worse.

what do i do ? i know the cause of my acne but now i dont know how to fix it despite being back on my normal routine for about a month now. please help.

also my diet is good. i have reduced sugar intake and i drink plenty of water and i cut out diary. im 17 and my acne is mainly on my cheeks, my forehead is completely clear and my chin has few problem spots.
