HIFU, or High-Intensity Focused Ultrasound, is a non-invasive and non-surgical cosmetic procedure that uses ultrasound waves to stimulate collagen production and tighten the skin. The treatment involves the use of a handheld device that delivers focused ultrasound energy to the deeper layers of the skin, which causes a controlled thermal injury that stimulates collagen production and tissue regeneration. HIFU is typically used to treat a range of skin concerns, including fine lines, wrinkles, sagging skin, and uneven skin texture. The procedure is painless and requires no downtime, making it a popular choice for those looking to improve their skin’s appearance without surgery. The results of HIFU treatments are typically visible immediately, with continued improvement over several months as collagen production increases
