Upper lip laser hair removal burn. Is this common? (Photo)

Laser hair removal burns are very common but should not be happening if you go to a well trained physician.  I suggest wound care with janmarini bioshield and dermflage.  Best, Dr. Emer.

Though this isn't a common side effect (hence your last few treatments not showing this), it is possible to experience blisters after any laser treatment. This also could be a form of dermatitis, which is a temporary inflammation of the skin. If your skin doesn't heal within the next 10-14 days, contact the doctor who performed the treatment.
