Hey guys. So a couple months ago I had a small whitehead. I took a towel and I tried to rub the whitehead off. Unfortunately, I caused a burn on my skin by rubbing to hard. Anyways, a scab began to form and I peeled the scab off because I am an idiot. Anyways its been 2 months and the skin is still sort of red and pink. Should I try to start exfoliating this skin to fade these marks?
