16 May 2019 There are a number of possible indications for treatment with intense pulsed light: Vascular malformations; Telangiectasias in the neck; Varices in the legs. Skin photo-rejuvenation , which improves texture and colour changes inherent in ageing, is also possible with pulsed light. This technique is practically painless and has no side effects , provided that suitable parameters are respected. Intense pulsed light treatments use a non-coherent polychromatic light source with a broad spectrum of wavelengths (between 410 and 1200 nm). Interposing filters cut off the radiation below the filter: In lighter phototypes it can filter below 515 nm; In darker ones it can cut below 560-580 nm. In each situation, the physician will define the duration and number of treatments.
