Hello, line carving can change the nose. Its principle is mainly to shape the tip of nose, the back of nose and the alar. Thread carving rhinoplasty takes specially designed absorbable protein thread as a scaffold and pushes it into the columella and the back of the nose, thus lengthening the tip of the nose, narrowing the alar, raising the contour of the nose and enhancing the three-dimensional sense of the nose from all angles. After the thread is injected into the nose, it will stimulate the collagen production of the nose tissue and make the nose shape straight and convex. However, the collagen once produced will be slowly absorbed by human tissues, and the effect will gradually disappear after absorption. The general maintenance time is about one year.
