Effect and mechanism of intense pulsed laser on skin aging in rats.

Abstract

OBJECTIVE To explore the effect of intense pulsed laser (IPL) on anti-aging and its mechanism. METHODS Rat skin was continuously irradiated ex vivo by IPL at certain wavelengths with different energy densities. The rats were irradiated twice with an interval of 2 weeks. We measured superoxide dismutase (SOD) activity, malondialdehyde (MDA) content… (More)
