Laser resurfacing uses a laser to send out brief pulses of high-energy light that are absorbed by water and substances in the skin. The heat energy from the laser vaporizes thin sections of skin, layer by layer. New, fresher skin grows over the treated area resulting in an improved appearance. The procedure also heats the layers underneath to promote collagen production, which stimulates skin in the treatment area to heal in a smoother, more even appearance.
Why choose laser resurfacing for scars
Laser resurfacing is most effective for treating superficial scars caused by acne, surgery or trauma that are not growing or getting thicker.
What you should know about laser resurfacing for scars
The scar is cleaned and marked with a pen. Often a local or topical anesthetic is used to numb the area before treatment. Some patients are given a sedative or anti-anxiety medicine to relax. Patients being treated for facial scarring may need to wear goggles to prevent eye damage by the laser. Wet towels will be placed around the treatment area to absorb excess laser pulses. The laser is passed over the skin several times. In between passes, the scar is wiped with water or a saline solution to cool the skin.
The process may sting or burn slightly. Some patients feel a snapping sensation against their skin. Little or no bleeding occurs in most cases, although severely damaged skin may bleed. When the treatment is finished, the area is covered with a clean dressing or ointment.
