I REALLY think you should be examined by YOUR doctor instead of soliciting medical advice on-line. The "blisters" you are referring to may be the result of the energy imparted to the skin and in that case would resolve as long as the face is moisturized as it is healing. However, it could also be the result of a viral infection and would need to be aggressively treated. You paid a physician to both perform AND follow you after the procedure. It is really in your best interest to be seen by him. Dr. Peter Aldea
If you can get a prescription for Biafine, I would use that, otherwise Eucerin Aquaphor. Also consult your physician, in case this might be herpetic or impetigo.
