Intense pulsed light (IPL) is one of the most effective nonablative approaches to treat skin photoaging. The broad range of wavelengths (500–1200 nm) emitted from IPL devices effectively target both melanin and hemoglobin in the skin. Numerous trials show the effectiveness and compatibility of IPL devices in a variety of skin conditions, especially in cosmetic indications such as hypertrichosis...

Background: Intense Pulsed Light (IPL) technology is one of our new measures in treating dermatologic disorders including undesirable skin pigmentation. In contrast with lentigines and freckling of the skin, few reports about nevus spilus treatment using intense pulsed light have been published. The aim of current study was to evaluate efficacy and safety of nevus spilus treatment with an inten...

Combining the molecular specificity of the infrared spectral region with high resolution microscopy has been pursued by researchers for decades. Here we demonstrate infrared supercontinuum radiated from an optical fiber as a promising new light source for infrared microspectroscopy. The supercontinuum light source has a high brightness and spans the infrared region from 1400 nm to 4000 nm. This...

Angioma serpiginosum (AS) is a nevoid capillary malformation developed congenitally or thereafter. The AS stops growing after puberty and may remain persistent throughout life. The pulsed dye laser (PDL) and KTP are used to treat the AS usually after several sessions. We treated a patient with AS with only one session of intense pulsed light (IPL) therapy. A 40-year-old lady with Fitzpatrick sk...

A hydroquinone/tretinoin (HQ/tret) skin care system designed for use with non-surgical facial rejuvenation procedures has recently become available. In this observer-masked study, 36 patients with moderate-to-severe wrinkling of the skin around the eyes and lips were randomly assigned to use either the 4% hydroquinone/0.05% tretinoin skin care system or placebo products, each day for 90 days. I...
