The most aging part of the face is not the bags under the eyes or the deep furrows on the forehead, but the two lines extending down the side of the nose, which we call: the decrepit lines. These lines are almost invisible to young and well-maintained people, but if the lines are deep and long, it will give people the first impression that the person is not young. It is a typical phenomenon of aging skin tissue that causes depressions on the surface of the skin. The two main reasons for the formation of the lines are the aging and sagging of the skin and excessive expression. According to facial science, the wrinkles on both sides of the nose can reflect the weight of a person’s speech, people with deep wrinkles have to listen to everyone, while people with shallow wrinkles or no wrinkles have no one to listen to them. These two deep wrinkles can give orders, so it is called the decree line, and we say the eight lines. The above is the scientific reason why people often say that people with deep lines are hard to get close to. The more pronounced the facial lines, the more serious, old and unfriendly you look, making it difficult for people to get close to you. The three main reasons for the birth of the lines 1, skin aging sagging Undeniably, some people are born with heavier lines than others, but in general, after the age of 30, the lines will slowly deepen. In addition to genetic factors, mainly due to age factors. As we grow older, the collagen and water content in the skin will gradually lose, and the subcutaneous fat will also shrink and sag, causing skin relaxation and aging, forming a depression on the surface of the skin, which will produce the lines. 2, too much expression Want to know what kind of expression your lines appear because of? It is very simple. If the lines extend from the side of the nose to the corner of the mouth, it is because you love to smile too much and formed; if the lines extend down from the corner of the mouth, then you should review whether you like to purse your lips and skim your mouth too much! 3, air pollution, computer phone radiation and irregular daily routine Air pollution, computer phone radiation and irregular daily routine will also speed up the generation of lines, so to solve the problem of how to get rid of lines should avoid the occurrence of these situations. Hyaluronic acid injection to get rid of decrescent lines Before removing decrescent lines, the doctor will first draw the corresponding fat location according to the texture of decrescent lines to determine the injection range, and inject a small amount of anesthesia under the injection site. Hyaluronic acid is then injected as a filler into the dermal folds and depressions to immediately remove wrinkles and change the appearance.
