High-Intensity Focused Ultrasound (HIFU) is a non-invasive technology used to tighten and rejuvenate the skin. Unlike most laser or radiofrequency systems that primarily affect superficial layers, HIFU delivers focused ultrasound energy to deep foundational tissues, including those up to 4.5 mm beneath the skin surface, without causing surface damage or scarring.
When applied to the brow area, these precise ultrasound waves generate thermal energy in the targeted tissue. This controlled heating stimulates the body's natural regenerative processes, initiating tissue repair and collagen production. Over time, this process leads to improved skin elasticity and cellular renewal, effectively lifting and firming the brows to reduce sagging.
The procedure is typically quick, lasting approximately 10-20 minutes, and offers a convenient solution with minimal downtime, allowing individuals to resume daily activities immediately. Depending on the degree of brow ptosis, a single session may be sufficient, or multiple sessions might be recommended for optimal results. While some immediate tightening may be observed, the full, desired effects typically develop gradually over approximately three months as collagen remodeling progresses.
