Abstract
BACKGROUND: Nonablative laser systems that integrate optical and conducted radiofrequency (RF) energies are a novel technology for the treatment of wrinkles. OBJECTIVE: This two-center study investigated the safety and effectiveness of combination diode laser (900 nm) and RF for the treatment of wrinkles and skin texture. METHODS: Patients with grade II to IV wrinkling on the face, according to the Glogau classification system, were treated with a combination diode laser and RF using a fluence of 30 to 50 J/cm2 and RF energy of 80 to 100 J/cm3. Patients received up to three treatment sessions at 2- to 3-week time intervals. Wrinkle assessments using the Glogau scale were conducted at baseline and at 3 months following the last treatment. In addition, patients and physicians graded the level of improvement using pre- and post-treatment photographs. RESULTS: Twenty-three subjects completed all three treatment sessions. Of these participants, more than 50% had a greater than 50% improvement in the appearance of wrinkles. All subjects reported a noticeable improvement in skin smoothness and texture. CONCLUSION: This preliminary study demonstrates that the combination of diode laser and RF energies decreases the appearance of wrinkles and improves skin texture.
