Superficial intense focused ultrasound on periorbital wrinkle

The periorbital wrinkles are easily perceived evidence of aging, so become a major concern for many patients. Various treatments have been attempted to improve periorbital wrinkles, but the need for new treatments that are less invasive and more effective is still high. In this study, we evaluated the safety, clinical and histological effects of intense focused ultrasound using only a 1.5 mm transducer in the management of periorbital wrinkles. Ten adult Korean females were enrolled. The treatment effect and safety profile were evaluated up to 3 months after 1 session of IFUS treatment on the periorbital wrinkles. The mean subjective satisfaction score was 3.2 ± 0.79 (mean ± standard deviation) by 5- point scale. The mean objective clinical improvement score was highest in the fine wrinkle on the crow's feet area and lowest in the deep wrinkles of the infraorbital and crow's feet area. Histometrically, increase of collagen and elastic fiber density was observed in the all layers of dermis. No serious side effects occurred after the treatment. In conclusion, intense focused ultrasound treatment using a 1.5-mm transducer alone can significantly improve periocular wrinkles after a single treatment with a good safety profile.
