4D HIFU Skin Rejuvenation Working Theory
4D HIFU (High-Intensity Focused Ultrasound) is a non-surgical procedure that uses ultrasound energy to lift the skin and shape the body.
HIFU directly delivers heat energy to skin and subcutaneous tissue that can stimulate and renew its collagen, consequently improving the texture and reducing its sagging. HIFU will heat the SMAS layer up to 60℃~70℃. The heat energy raises the therma coagulation point, accelerating the skin rejuvenation process, and maximizing the skin layer’s tightening effect.
