Combined use of high-intensity focused ultrasound and fractional co2 laser effects in the correction of age-related skin changes

Aim. To develop and evaluate the use of combined effects of high-intensity microsfocused ultrasound and fractional ablative CO₂ laser at low parameters in one procedure.

Materials and methods. We observed 78 women aged 47–55 years. Patients received a procedure of focused ultrasound exposure on the face area (Amplifay protocol, 800 lines) according to the recommended energy parameters in order to correct age-related skin changes on the Ulthera system (RU FSZ 2010/06662 from 08.18.2011, acts indefinitely), in the form of monotherapy or combined with ablation fractional laser exposure on the face with Cosmopulse-2. Two groups were identified depending on the research method.

Results. The combination of focused ultrasonic exposure and fractional CO₂ laser had a positive effect on the index of the dermatological index of quality of life (DIC), and was significantly better than with mono-exposure of focused ultrasound, both in the early and in the long term. The coefficient of ultrasonic density of the dermis in the main group is significantly higher than when using the monovariant use of focused ultrasound, which indicates a pronounced collagenogenesis, while the indicator of the thickness of the dermis, which reflects the state of intradermal edema, is significantly less in the study group than in the control group. This gives reason to recommend this combination of procedures, which has a synergistic effect on the aesthetic profile of the patient, and on the other hand, significantly reduces ayuschy and facilitates the recovery period, contributing to a rapid decrease in swelling and local phenomena neuropathy.
