Facial Lasers’ Future: Shorter Downtimes, Darker Skin Types

GLOSSARY
halo
1. The faintly hued ring that is seen to surround a light source viewed through fog or light clouds. The size of scattering particles determines the size of the ring. 2. The ring surrounding a photographic image of a bright source and resulting from the scattering of light in random directions.
fractional photothermolysis
A laser skin-resurfacing method that creates microscopic thermal wounds referred to as microscopic treatment zones (MTZs), which are surrounded by uninjured tissue. The MTZs are usually arranged in a grid pattern and are invisible to the naked eye. This patterned approach is less intense than the nonfractional methods in which all of the skin surface is treated. The MTZs create smaller injuries and shorter migratory pathways of wound-filling keratinocytes, resulting in faster skin repair.
