Laser resurfacing; technique using laser therapy to remove fine lines and wrinkles, pigmented areas, and tattoos.


(fo?to?ther-mol'i-sis) [ photo- + thermolysis]
The use of light produced by lasers to produce heat damage. photothermolytic (-mo'lit-ik), adjective

fractional photothermolysis

A method of laser skin resurfacing in which laser energy is directed at pinpoint, broadly separated islands of skin instead of larger swaths to remove cosmetically unappealing blemishes in skin color and texture. The technique is used to minimize the time it takes to restore normal epithelium to the treated surface.
Synonym: fractional ablation

selective photothermolysis

The use of short pulses of light to treat skin conditions. This method causes less damage to normal tissue than do continuous beam lasers.

[91,92] Non-selective destructive argon and carbon dioxide laser therapy has been superseded by advanced laser technologies that rely on the concept of selective photothermolysis. [94] These produce preferential and minimal injury to pigment-containing structures by using wavelengths that provide selective absorption and pulse duration less than or equal to the time taken for the heat to dissipate from the target tissue to surrounding structures.
