the dermal collagen fibers shrink,tightening the loose skin wrinkles,while rearranging the collagen proliferation and repairing the aging and damaged collagen layer,thus achieving the effect of wrinkle removal and skin tightening. thereby producing a thermal coagulation effect on the skin, forming a mesh coagulation point in the dermis and fascia layer, stimulating the contraction and firming of fibers and collagen, regeneration and repair, and achieving layer-by-layer lifting and firming. The latest patented ultra-pulse shock wave technology of V-HIFU and P-HIFU is used to generate high-energy focused ultrasound, which quickly passes through the epidermis..syi
