ADVANCES IN THE USE OF MICROFOCUSED ULTRASOUND FOR FACIAL REJUVENATION

The demand for non-invasive technologies to address facial rejuvenation and achieve a lifting effect has increased significantly over the past decades. Micro-focused ultrasound is a technology capable of inducing microthermal lesions at varying tissue depths, including the superficial musculoaponeurotic system (SMAS) and the dermis. Following the formation of these lesions, determined by power adjustment and the precise delivery of concentrated energy across different layers, a healing process is initiated, ultimately leading to SMAS contraction and dermal restoration, primarily associated with collagen synthesis. Accordingly, this study aimed to evaluate an application strategy utilizing micro-focused ultrasound on the facial region and to assess the outcomes resulting from this therapeutic approach. The findings demonstrated improved tissue support, particularly in the subocular region, temples, and nasolabial fold. Thus, it can be concluded that the use of micro-focused ultrasound on the facial region is a safe and effective therapeutic approach for treating skin aging, as it enhances tissue support and restores the tissue matrix, which also contributes to improved skin laxity.
