so i used to have sever acne around 6 years ago in my teenage but i cleared it up and was acne free with a clear skin for around 3 years and then i started getting acne again due to poor sleep and stress. later i cleared that too but for the past year or so ive been getting this type of "acne" only around my mouth and nose and its been a real nuisance to me, i dont understand if its bc of poor sleep or stress or some other factor? also my skin has gotten a lot worse than it used to be since a year. ive gotten back to having a proper skin care routine but this problem still seems to persist
