What is "photorejuvenation"

n. A skin treatment that uses intense pulsed light or other thermal or chemical methods to treat some skin conditions and remove wrinkles arising from photoaging.

Photorejuvenation is a skin treatment that uses lasers, intense pulsed light, or photodynamic therapy to treat skin conditions and remove effects of photoaging such as wrinkles, spots, and textures. The process induces controlled wounds on the skin, prompting it to heal itself by creating new cells. This process reverses the signs of photoaging to a certain extent by removing appearances of damage. The technique was invented by Thomas L Roberts, III using CO lasers in the 1990s.
