Laser resurfacing removes the top layer of skin. This is also known
as laser dermabrasion or laser peel. The laser releases short pulses of energy
that cause a carefully controlled burn of the skin. This promotes new skin and
collagen growth. Because it can be finely controlled, laser resurfacing has
largely replaced chemical peels and dermabrasion as the preferred method for
treating most
acne scars.
Doctors use a variety of lasers, including the CO2 laser and the YAG
laser.
As in dermabrasion and chemabrasion, redness and tenderness can last
from several weeks to months after the procedure. Further scarring is possible,
although rare.
To prevent skin discoloration, avoid sunlight for several months
after treatment by using sunscreen and hats outdoors.
