Vbeam®, 595nm-long pulsed dye laser with adjustable pulse duration (ALPDL), is a kind of pulsed dye laser with 595nm wave length with maximum energy fluences of 40J/cm2. The pulse duration is adjustable from 0.45 ms through 40 ms and it is equipped dynamic cooling device® which makes the surface of the targeted skin cooled with tetrafluoroethane gas (−26.1°C). The longer wavelength allows the laser beam to penetrate deeper in the skin, and the longer pulse duration with high-energy fluences is considered to be optimal for damaging larger caliber vessels with less side effects such as pigmentation or scarring. ALPDL has 5 different round spot sizes and 3×10mm rectangle spot. Pigmented lesion handpiece has been developed for pigmented skin diseases such as senile lentigo which allows the pigmented lesion to be eliminated without impacting underlying blood vessels.
ALPDL has been used to treat various skin diseases such as portwine stains, strawberry marks, teleangiectasia, senile lentigo, viral warts, acne, hypertrophic scar/ keloid, psoriasis, and photoaging, and proved to be effective for treatment of most of these diseases. We report here the efficacy and availabilities of ALPDL to these diseases.
