OBJECTIVE The purpose of this clinical study was to evaluate the effectiveness of an intense pulsed light (IPL) irradiator system for the treatment of benign pigmented lesions. MATERIALS AND METHODS A total of 18 patients with lentigo solaris and eight patients with melanocytic nevi were treated once with an IPL system. After 2 months, the effect was evaluated on close-up photographs. RESUL...

A 69-year-old Caucasian female consulted our department for treatment of pigmentary ochre dermatitis secondary to a chronic venous insufficiency of 25 years’ duration. She presented purpuric macules and patches, ochre-brownish in color, on the lower third of both legs with no discomfort except her aesthetic problem (Figure 1). The patient made no reference to taking any medication or to having ...

BACKGROUND The flashlamp-pumped pulsed dye laser (585 and 577 nm) has proven to be a very effective and safe treatment option in the therapy of essential telangiectasias (ETE). Nevertheless, the postoperative intracutaneous hematomata, which most patients see as cosmetically disfiguring, always has been a matter of concern. OBJECTIVE To test the efficacy and safety of a new, large spot size, ...

OBJECTIVE The purpose of this clinical study was to evaluate the efficacy of an intense pulsed light (IPL) irradiator system for the treatment of port-wine stains (PWS) resistant to multiple pulsed dye laser (PDL) treatments. MATERIALS AND METHODS Fifteen PWS patients, who were previously found to be resistant to multiple PDL treatments, were treated four times with a second generation IPL sy...

The role of light-based technologies in dermatology has expanded dramatically in recent years. Lasers and intense pulsed light have been used to safely and effectively treat a diverse array of cutaneous conditions, including vascular and pigmented lesions, tattoos, scars, and undesired hair, while also providing extensive therapeutic options for cosmetic rejuvenation and other dermatologic cond...

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...
