Fractional resurfacing laser, pixel aesthetic laser

The abundance of facial skin care regimens and their enthusiastic promotion in popular media is the modern expression of an ancient desire to attain beauty and recapture a youthful appearance. As the face ages, skin quality deteriorates. One method of improving the condition of the skin is by “resurfacing” it, i.e. by removing the outer layers to the level of the papillary dermis. Removing the outer skin layers to papillary dermis level induces re-epithelialization and new collagen formation, which can create a smoother, even-toned, and more youthful appearance.

In the late 1980s, laser technology applied to skin resurfacing was discovered to yield more predictable depths of injury when compared with chemical peels or dermabrasion. The first laser used for skin resurfacing was a pulsed carbon dioxide (CO₂) laser. Later, the erbium:yttrium-aluminum-garnet (Er:YAG) laser was introduced, which has now become a standard tool for skin resurfacing.

Fractional laser photothermolysis is the latest in the broad range of Er:YAG laser techniques. This technique promises a novel means of providing treatments that would be as effective as traditional Er:YAG approaches while further reducing their downtime and risk . The fractional technique is based on a concept of producing an array of microscopic wounds on the skin surface that are rapidly re-epithelialized by the surrounding, undamaged tissue, sparing the epidermis in the untreated areas. Here, we describe the latest PST (Pixel Screen Technology) fractional technique for minimally invasive Er:YAG skin rejuvenation.
