I have oily combination skin and kind of sensative sometimes with something strong to my face such as Vitamin C or retinol. I got VI peel for the first time to remove melasma on my cheeks. There was stinging and a little burn at the begining but nothing hurt. It took me almost 2 weeks to finish peeling but I noticed that there were some spots which is like burn didn't wanna peel. And after they finally peeled, they left me some red spots like scar. I need an advice...
