Abstract:
Various intrinsic and extrinsic factors contribute to facial aging, primarily manifesting in the skin and soft tissues. As aesthetic standards continue to rise, there is an increasing demand for facial rejuvenation. Photoelectric and ultrasonic technology utilizes energy conversion to thermally affect tissues, improving sagging and laxity in the skin and soft tissues through controlled thermal injury that induces beneficial heat effects. This technique has gained popularity due to its rapid, effective, and minimally invasive nature. To achieve optimal result without experiencing excessively harmful thermal effects, it is crucial to properly manage tissue thermal damage. The mechanisms of action for photoelectric and ultrasonic devices used in facial rejuvenation are summarized in this work, along with the effects of heat and thermal injury at various temperatures on tissue cells and molecular biochemistry. Factors influencing thermal effects are also discussed, aiming to optimize treatment parameters and guide safe and effective anti-aging therapies.
