Deep pulse fractional CO2 laser combined with a radiofrequency system: results of a case series.

OBJECTIVE The purpose of this study was evaluation of the safety and efficacy of this new combined technology that adds deep ablation to thermal stimulation. BACKGROUND DATA Minimally ablative or subablative lasers, such as fractional CO2 lasers, have been developed in an attempt to achieve the same clinical results observed with traditional ablative lasers, but with fewer side effects. Despite being an ablative laser, the system used in this study is able to produce a fractional supply of the beam of light. Fractional ablation of skin is performed through the development of microscopic vertical columns surrounded by spared areas of epidermis and dermis, ensuring rapid wound healing and minimum down time. Simultaneous synchronized delivery of a radiofrequency (RF) current to the deeper layers of the skin completes the therapeutic scenario, ensuring an effective skin tightening effect over the entire treated area. METHODS Nine adult patients were treated for wrinkles and acne scars using this new laser technology. An independent observer evaluated the improvement using a five point scale. RESULTS All patients had good results in terms of improvement of skin texture, with mild and transitory side effects. CONCLUSIONS This novel combined system produced improvement in wrinkles and acne scars, with progressive enhancement of skin tone and elasticity.
