0? 2? 0? The grooves on both sides of the nose are called "nasolabial groove" in medicine and "decree pattern" in Hong Kong and Taiwan, which are the characteristic signs of middle-aged people's faces. They are shown as "eight-shaped" sulcus from both sides of the nose to the corners of both sides, and the length and depth of the sulcus will increase with age. There are two main reasons: first, the loose skin on the face sags downward under the action of gravity; Secondly, there are facial muscles and ligaments hanging in the deep part of the nose and upper lip, which are relatively fixed when calm, and will move upward when expressive, so a crease groove is formed at this intersection. Mild nasolabial groove, filling the groove with skin filler injection or photoelectric skin lift to tighten the skin; For moderate nasolabial groove, you can choose sawtooth line suspension and small incision wrinkle removal, pull the loose skin upward and narrow the nasolabial groove; Severe nasolabial groove can only be treated by large face lifting surgery.
