The Safety and Efficacy of a Dual CO 2 and 1570-nm Hybrid Laser for Periorbital Rejuvenation.

Background: Many modalities are used for periorbital rejuvenation, with a wide range of efficacy and safety. To achieve favorable outcomes with minimal downtime and adverse effects, professionals developed a hybrid laser, which allows simultaneous treatment with 2 wavelengths: fractional ablative and fractional nonablative lasers.

Objective: To evaluate the safety and efficacy of a new hybrid laser for periorbital rejuvenation. Materials and

Methods: This retrospective single-center study includes 24 patients who underwent a single-pass treatment with a CO 2 and 1570-nm hybrid laser for periorbital rejuvenation between 2020 and 2022. Patients' standardized clinical photographs before and after the treatment were assessed by 4 independent physicians for objective improvement. Treatment data, safety, and patients' satisfaction were also reviewed.

Results: Statistically significant objective improvements were found in all investigated scales with an improvement of 1 to 2 points on each scale. Patients' satisfaction was 3.1/4. Average downtime was 5.9 ± 1.7 days. Most adverse effects were mild to moderate in severity (89.7%), including erythema, crusting, pruritis, edema, and hyperpigmentation.

Conclusion: After a single-pass treatment, the laser generates 26% to 50% improvement in the periorbital area, with a strong safety profile and a relatively simple recovery. Further research is needed to validate the efficacy of this technology compared with more aggressive modalities.
