This study aimed to evaluate efficacy and safety of 675-nm laser for dorsal hand rejuvenation in Thai patients. Twenty-six subjects aged 50 to 65 years diagnosed with wrinkle and solar lentigines on both dorsums of hands were included and treated with RedTouch for 3 times every 4 weeks. Then, they were follow up at 3 and 6 months after the final treatment. The measurement of 5-point Global Aesthetic Improvement Scale scores by physicians and subjects were conducted. Moreover, pigmentation level, wrinkle and texture were also recored using Antera. Elasticity was measured using Cutometer.
RedTouch parameter included Moveo, power 5 W, Energy/DOT 500 mJ/DOT, then Standard, power 4 W, spacing 2000 μm, 1 pass per side.
