What Happens to Facial Hair After Laser Resurfacing?

Yes, you will probably have your “peach fuzz” grow back. Most patients see their hair regrow but it could be that there may be patchy areas of diminished growth.

Laser resurfacing withy CO2 or Erbium lasers does not remove facial hair.
Hair removal requires the laser energy to go much deeper than the resurfacing lasers go.
If the CO2 or Erbium resurfacing laser went deep enough to remove hair follicles you would be scarred.

The hair follicles will not be injuried by laser resurfacing. In fact, the follicles help in the healing process. You may have a temporary reduction in the facial hair after the treatment but any loss will regrow.
