The HIFU system is a system that applies a low amount of focused ultrasound energy to the lower layers of the skin. The heat generated by ultrasound energy acts by stimulating the production of new collagen. The results of the treatment applied in 3 sessions begin to be seen immediately after the application. Real results begin to be noticed visibly 1 month after the first application and become apparent up to 4-6 months. The durability of the effect is about 1-1.5 years. At the end of 1 week after the non-surgical facelift, the skin feels even better.
