Split-face comparison between single-band and dual-band pulsed light technology for treatment of photodamage

Abstract

Both single-band and dual-band IPL technology are safe and effective in the treatment of photodamaged facial skin. IPL treatment with a single-band handpiece yielded results comparable or superior to dual-band technology.

Treatment of injection‐induced ecchymoses with light/laser‐assisted technology

“…Therapeutic options for ecchymosis have traditionally focused on preventative measures, including improving injection technique, steroid injection, application of hydrogen peroxide 15%, parallel use of cooling systems and use of vitamin K cream in patients with bleeding disorders, yet none have shown consistent effectiveness (Alegre‐Sánchez et al, ; Lemperle et al, ; Molenda et al, ; Nestor et al, ; Urdiales‐Gálvez et al, ). In recent years, several laser and light treatment options have been described (Alegre‐Sánchez et al, ; Funt & Pavicic, ; Morton, Smith, Dover, & Arndt, ; Varughese, Keller, & Goldberg, ). These modalities target the hemoglobin of extravasated red blood cells and have been shown to shorten the time to resolution of ecchymoses from 14 days to 24–48 hr.…”

“…Recently, a narrow‐band intense pulsed light (IPL) emitting green light mainly between 500 and 600 nm, was developed for the treatment of vascular lesions (Varughese et al, ). This spectrum narrows the generally broad optical spectrum of IPL technology to primarily target oxyhemoglobin and deoxyhemoglobin, providing greater precision and safety.…”

Efeitos fisiológicos e terapêuticos da luz intensa pulsada

“…Além disso, os modelos mais recentes incorporam mais de um filtro que bloqueia os comprimentos de onda mais curtos e longos, resultando em uma faixa estreita de luz. O intervalo de comprimento de onda destes dispositivos de LIP de banda estreita pode permitir um tratamento mais seguro de lesões vasculares [17,18].…”

Light‐based devices in the treatment of cutaneous vascular lesions: An updated review

“…Additionally, newer models incorporate more than one filter which block both shorter and longer wavelengths, resulting in a narrowband IPL that emits broadband light over a narrow wavelength range such as 500‐600 nm. The wavelength range of these narrowband IPLs may allow safer treatment of vascular lesions …”

“…The wavelength range of these narrowband IPLs may allow safer treatment of vascular lesions. 52,53 Intense pulsed light can be delivered as single, double, or triple pulses in the millisecond range, which provide added protection to the outer epidermis. 54 A transparent cool gel is also applied to the skin before treatment to minimize epidermal damage and increase the efficiency of light delivery to deeper structures.…”
