Thanks for the query.
Kindly revert to the Dermatologist who did the procedure. He is in a best possible position to help you as he understands the type and power used in the laser, for what indication it was done. Sometimes it's not burn but a known adverse effect with erythema and swelling. Topical steroids with moisturiser should help but check with your treating Doctor. Hope it helps you
There is a lot of chances that it will revert back to normal.
