These laser peels remove the superficial layer of the skin and reduce the appearance of fine lines, wrinkles, and pigmented spots, leaving behind vibrant and youthful skin. The NanoLaserPeel usually goes up to about 4 microns, while the MicroLaserPeel goes from 4 to 50 microns. Both of these treatments are confined to the epidermis—the outermost, superficial portion of the skin. One micron is equivalent to 1/10,000 of a centimeter or 1/2,540 of an inch.
