WebFractional photothermolysis (FP) combines the efficacy of ablative and the tolerability of non-ablative laser treatment in some skin conditions. There are few studies on using FP in melasma and its value cannot be estimated presently. Review of the literature and the authors' own experience show a definite potential which should be further ... WebApr 27, 2024 · Selective photothermolysis. Permanent hair removal with the use of laser or IPL technologies works due to the selective photothermolysis principle. This means that the devices are calibrated on the wavelength that is selectively absorbed by the hair, which will consequently absorb the light emission transforming it into thermal energy causing ...
WebApr 13, 2024 · PDL was the first laser device developed that utilized the concept of selective photothermolysis to manage vascular lesions [3,23]. Despite its proven therapeutic efficacy and safety profile, patient acceptance of this treatment option may be limited by the appearance of purpura at the treatment site, which can persist for 7–14 days .
