The eight lines, also called decrepit lines, consist of two lines on the side of the nose. The longer the lines are, the older they appear. They are mainly caused by sagging skin, atrophy of subcutaneous fat, and loss of collagen resulting in depression of the facial skin surface. The longer the normal lines, the older the person is, it’s true. You can look at a picture: no joke, there is a difference of several years between having and not having a decrement line. In general, the clinical use of “improve facial skin laxity” or “injection filler” two methods to eliminate the decrepit lines. For more serious lines, a combination of treatments is recommended to better improve the shape of facial aging. I. Mild lines For this type of lines, injections of fillers can be improved. At present, the safe and reliable ones are hyaluronic acid, autologous fat particles injection, etc. Which one is better? 1, maintenance time Autologous fat filling to the temple hollow area, once the fat cells survive, it is permanent; while hyaluronic acid maintenance time is related to the size of the molecular weight and autologous absorption, generally can be maintained for about 6 months, if you want to maintain a long time, you need to inject regularly. 2.Shaping Hyaluronic acid has different sizes of molecular types, which can not only be used to fill depressions, but also has good shaping effect. Autologous fat is not so effective in shaping, but it is more valuable because of its soft and natural appearance after filling. The last point is that only by filling the right amount precisely can we ensure the parallel status of the decrepit lines and the face after filling. This kind of decree lines from the degree of skin relaxation is not serious, no sagging or mild sagging, can be improved by improving the degree of facial relaxation, such as thread sculpture. Thread sculpture is to bury medical threads into the skin below the dermis or under the skin to create tension in the skin in the desired direction and lift the sagging skin and fat, not only will the facial contour look tighter and younger, but the lines will also be improved. Since thread sculpting is not done in the fascial layer (smas layer) to peel and muscle lifting to reset, the maintenance time is usually about 1 year. This level of wrinkles, the candidate’s face is likely to be sagging, sagging, and collagen loss is serious, at this time, facelift surgery can improve the sagging and wrinkles of the skin. If you want to go back to the way it was 10 or 20 years ago, you need to inject fillers (such as hyaluronic acid, autologous fat, etc.), so that the “facial rejuvenation” effect is obvious and the lines are improved more thoroughly.
