3 weeks post Cosmelan mask. Is there anything I can apply to soothe the burning?

My face is red, sore, peeling/flaky and still stings whenever I apply the Cosmelan2 cream or hydra vital cream or sunscreen. Anything at all, even the face wash stings. It's been 3 weeks since the mask, perimeter of my face darker than the insides. Is there anything I can apply on my face to sooth the burning? Thanks. Mimie
