BACKGROUND Intense pulsed light has been used in the treatment of photoaging without a full understanding of its mechanism of action. OBJECTIVE To study the effect of intense pulsed light on photoaging and on the skin immune response by means of a clinical and histopathological study, evaluating Langerhans cells (CD1), expression of intercellular adhesion molecule, of CD4 and CD8 lymphocytes ...

DOI:10.1167/iovs.14-15764 PURPOSE. To evaluate the effect of intense pulsed light (IPL) applied to the periocular area for meibomian gland dysfunction (MGD) in a prospective, double-masked, placebo-controlled, pair...

the lethality of pulsed ultra-violet (uv) rich light for the inactivation of pathogenic bacteria has been investigated. a low pressure xenon filled flash lamps that produced uv intensities have been used. the pulsed operation of the system enable the release of electrical energy stored in the capacitor into the flash lamp within a short time and produces the high current and high peak power req...
