A method of reducing scar formation associated with a skin wound includes providing an electromagnetic energy source, delivering energy from the electromagnetic energy source to opposing edges of a skin wound, and sealing the wound after delivering the energy. The electromagnetic energy source can include a laser, such as a fractional laser, including a fractional CO2 laser. Handpieces configured to reduce scar formation include one or more of a tissue eversion system, a medication delivery system, and a wound sealing system.
