4D HIFU uses probes of different depths (1.5mm, 3.0mm, 4.5mm) to accurately focus energy on the epidermis, fascia, and collagen layer; 4.5mm is located in the subcutaneous fascia layer, which produces protein coagulation reaction, thus producing tension around the coagulation point as the center and exerts tension on the fascia. Muscle layers grow and pull to achieve the best effect of shaping, lifting, and tightening; 3.0mm acts on the subcutaneous collagen layer to stimulate collagen regeneration, which can gradually tighten and improve skin and restore elasticity; facial wrinkles caused by sagging; one operation, comprehensive facial synthesis Pull up and tighten the whole contour.
