Q-S laser micro-drilling and multipass full-beam Q-S laser for tattoo removal — a case series

AbstractThe purpose of this study was to evaluate the safety and efficacy of a new combined method of Q-S laser-assisted tattoo removal. Ten patients with 13 professional, mostly mono-chromatic black tattoos were recruited. All tattoos received the same Q-S laser treatment sequence. An objective evaluation of tattoo clearing was assessed by careful analysis of a standardized collection of digital images taken from each tattoo, 2  months after each laser session, with the help of a custom-made pigment-fading percentage photographic ruler. The percentages of pigment clearance and side effects were evaluated by 4 independent dermatologists. Patient satisfaction and perceived discomfort during and post-procedure were evaluated according to specific scales. Clinical evaluators confirmed an average photographic pigment clearance of 97% after a median 4.85 treatment sessions. The Frac-Tat® method required 40% fewer sessions compared to those calculated by Kirby-Desai estimates. Photographic assessment of laser-exposed skin quality performed 2 months after tattoo clearing was considered almost comparable with untreated peripheral skin, confirming a very low side effect score. The Frac-Tat QS laser-assisted tattoo removal sequence used in our study showed a high degree of safety and efficiency, clearing exogenous pigm ents in a relatively few number of sessions. Preliminary ablative photo-acoustic fractional 1064-nm Q-S laser micro-drilling was considered an essential st...

This study aims to compare the efficacy and safety of 1565-nm non-ablative fractional laser (NAFL) and fractional microneedle radiofrequency (MRF) for treatment of SA striae gravidarum. Fourteen Chinese women with SA striae gravidarum were included in this study. Patient abdomens were randomly divided into NAFL and MRF treatment sides, treated three times at 6-week intervals. Treatment efficacy was evaluated by subjective (clinical assessments, patient satisfaction rating, adverse effects assessment) assessments and objective (skin melanin index measurement, histological study) assessments. Clinical assessment suggested MR...

This study aimed to assess and compare clinical effects, histological tissue damage, and wound healing after mono chromatic and sequential fractional laser treatments. In this prospective porcine model study, three adult female pigs were each irradiated using three different wavelengths: (a) monochromatic fractional ablative CO2 laser; (b) monochromatic fractional non-ablative 1570  nm laser; (c) sequential fractional 10,600 nm/CO2 followed by 1570  nm laser treatment. There were six power levels in the monochromatic 1570 nm laser, five in the 10,600 nm/CO2, and five in the sequential treatment. Th...
