1, to improve skin relaxation, is to tighten the skin epithelium and make the decree lines shallow. And because of the loss of collagen, just like the perennial soil erosion on the loess high slope, a ditch has been formed. Pulling alone can't solve the problem, so we must continue to fill the tissue to make it full. Autologous fat granules are commonly used in clinic, and the survival rate after injection is 30%-50%, which will be greatly improved after one injection. If it is not enough, it can be injected 2-3 times, which can generally achieve therapeutic effect.
2. Non-surgical methods: At present, injection of hyaluronic acid or collagen is safe and reliable. Hyaluronic acid is a substance contained in the human body, so there is no need to worry about adverse reactions or non-absorption. Hyaluronic acid can be degraded and absorbed for about one year after injection. After degradation and absorption, the metabolism is gone, which is safe and reliable. Collagen is also a substance for injection, but it is extracted from animal sources, mainly pigskin, and can also be injected, which is equally safe and reliable, and generally has no reaction from animal sources.
