Effects of the lower energy and pulse stacking in carbon dioxide laser skin treatment: an objective analysis using second harmonic generation

CONCLUSIONS: When combined, the results obtained in this study regarding anisotropy, entropy and density tend to demonstrate that it is possible to achieve collagen remodeling with the use of lower power levels associated with stacked pulses.PMID:33978061 | DOI:10.1590/ACB360304

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...
