Facial line carving is a plastic method to improve the sagging skin of the face, thus eliminating wrinkles and realizing facial rejuvenation. Literally, thread is a biological protein thread made of special materials, which means carving and shaping. But instead of carving from the outside of the face, the skin is pulled up from the subcutaneous layer of the face with absorbable protein lines, thus shaping the face and achieving the effect of a small V face, just like carving.
