I got a co2 laser 4 weeks back . When the peeling started the skin was pinkish/red . Despite of applying moisturiser and sunblock I have develop dark spots on the cheeks . One side the patch is big . On showing it to my doctor she has put me on steroids for 10 days and asked to use fcl skin lightening gel. I am little worried how long will it take for the pigmentation to go away ?and can getting a chemical peel done help ??
