Did tca peel a week ago son looks nice except i have a sore red dry patch on chin that stings when i put moisturiser on and won't go away?

Chemical burn: This is simply an area where the chemical treatment eroded more skin layers than desired. I suggest covering the affected area with Neosporin and loose-fitting bandages until the redness and irritation are gone. Avoid moisturizers until a full healing has occurred to avoid further irritation, aloe Vera gel may offer some relief from pain and also allow healing

Local abrasion: look like an abrasion on the chin. May use Neosporin cream (neomycin and polymyxin b) on the lesion, if not improving please see your physician
