Hybrid fractional laser treatment for photodamaged facial skin rejuvenation 6 years following fractional CO2 : Comparison of clinical outcome and patients' satisfaction.

ABSTRACT

OBJECTIVES: Fractional carbon dioxide (CO2 ) laser resurfacing is considered an effective treatment for skin rejuvenation. The request for clinical effectiveness with shorter downtime has led to the development of new hybrid technologies, including a traditional ErYAG (erbium-doped yttrium aluminium garnet) fractional laser 2940 nm combined with a simultaneous nonablative 1470 nm wavelength. The aim of this study is to compare clinical outcomes and patients' satisfaction with face resurfacing performed with both the CO2  laser and the hybrid laser. METHODS: Nineteen women underwent ultrapulsed CO2 fractional resurfacing for photodamaged facial skin; the same patients underwent the hybrid laser after almost 6 years. Clinical outcomes and patients' satisfaction were evaluated 6 months after the treatment and compared between the two technologies. RESULTS: After both CO2 and hybrid treatment a significant improvement was found in terms of fine lines (p < 0.001 and p = 0.004, respectively), tactile roughness (p < 0.001 and p = 0.002, respectively), and mottled pigmentation (both p < 0.001). Healing times and complications were greater with the CO2 laser. Comparing the two technologies, patients showed better results with the CO2 laser for each score's item, but greater satisfaction with the hybrid laser (p = 0.012). CONCLUSIONS: The present study confirms CO2 laser as the most effective treatment; however, the new hybrid technology revealed good results associated with faster healing and less discomfort.
