I used cosmelan 2 an left it on my face for 8hrs then my face turned red and on my 3rd day I peeled, but it didn't peel off completely. Majority of the area of my face turned dark after the redness wears off and it looks wrinkly and dry so it may be the dead skin that was suppose to peel but didn't, I only applied once because I was scared, because it turned red and I thought it wasn't a good idea if I put it again. I didn't consult a doctor before applying. What should I do?
