Objectives: This study evaluates the efficacy of a dual-pass technique using a mixed fractional laser device (10600 nm CO2 + 1550 nm fiber laser) for periocular rejuvenation Introduction: Periocular rejuvenation is a highly sought-after laser procedure in the aesthetic market, targeting the reduction of wrinkles, improvement of eyelid skin laxity, and correction of periocular pigmentation Materials / method: Twenty-five patients underwent a single laser treatment, preceded by a Visia® system analysis. Following 30 minutes of topical anesthesia (lidocaine + tetracaine), patients received two laser passes. The first pass used a 10600 nm wavelength in Hyperpulse mode (3 mJ energy/pulse, 200 dots/cm²), followed by epidermal scraping with saline-soaked gauze. The second procedure involved three passes with the 10600 nm and 1550 nm wavelengths in sequential mode (75 dots/cm²: 10600 nm at 5W, 1ms, 50% density; 1550 nm at 12W, 4ms, 100% density). Post-treatment assessments were conducted at 30 and 90 days Results: The treatment yielded a 54% reduction in periocular wrinkles, a 42% improvement in lower eyelid skin texture, and a 13% reduction in periocular hyperpigmentation. No immediate side effects were observed, though prolonged erythema lasting up to 45 days occurred in 8% of patients. No long-term side effects were reported. Conclusion: The dual-pass technique using a mixed fractional laser device offers significant improvements in periocular rejuvenation with minimal adverse effects. This method effectively addresses multiple aesthetic concerns with a single treatment, making it a valuable option for patients seeking comprehensive periocular rejuvenation.
