The hottest medical beauty project in the past two years is the “thread sculpture”. The “thread sculpting” is what doctors usually call “buried thread”. The basic principle of thread sculpting is to stimulate collagen growth by implanting special material threads inside the skin to significantly increase the density inside the skin, so that the skin texture becomes full and gradually enhance the sagging contours. The clinical side effects of thread sculpting surgery are mostly found in some unqualified cosmetic institutions, so that many candidates who have undergone thread sculpting surgery in these places experience: non-absorption of the threads; too many implanted threads, making the face stiff and unnatural. The number of wires used in the procedure should be determined by the location and the degree of aging, in order to get an effective lift, but also to ensure a natural state. In addition, thread sculpting is not done just once, but usually needs to last two to three times before the effect of tightening the contour can be seen gradually. The length and thickness of the thread, the shape of the thread, the depth of the implant, etc., all affect the effect of thread sculpting, so an experienced plastic surgeon must interview and design the thread to get a practical and targeted plan.
