scared skin from sulphur treatment?!

[lucy_87 1]

i used sulphur as a spot treament and although was told u could leave it on overnight it resulted in a preety bad scap on my cheek. it came off sometime when was sleeping and now i have scared skin. its not indented or anything, its like on the skin and is less noticeable when u stretch the skin out. does anyone have any ideas what i could do? or am i just stuck with it? its quite a big scar. also ive just been prescribed differin will that make it worse?

I wouldn't do much but apply neosporin like twice a day sort of keeping it moist. Anything else will mostlikely aggravate the situation and make it worse.
