Looking at the celebrity beauty’s palm-sized melon face and pointy chin, how can you feel that you are not perfect enough? Your chin is not sharp enough, or even short and receding? The curve is not obvious and smooth enough? Is this the way to accept the fate? In fact, plastic surgery is so developed today, just a small plastic surgery, you can have a perfect chin. A, the chin beauty standards Aesthetic definition: about one-sixth of the entire length of the face, from the side view and the eyebrows in the same vertical line, and slightly pointed, down the front at 45 °, which is the most exquisite chin. Medical definition: The tip of the chin is located exactly on the extension of the line connecting the tip of the nose and the upper and lower lips. If the tip of the chin is located a greater distance behind this line, it is a small chin; if, on the contrary, the tip of the chin is located in front of this line, it is a protrusion. In short, the lower lip, chin to the neck should present a natural, soft curvature. Chin, the scientific name of “chin”, according to the “three chambers and five eyes” of facial aesthetics, the chin is located in the lower 1/3 of the face, is the “three chambers” in the lower court, its size and prominence on the appearance of Its size and prominence play a vital role in the beauty of the contour of the face. The proportion and position of the chin, lips and nose determine the beauty of the facial contour. Therefore, even if the other parts of the face look good, a poorly formed chin will still spoil the overall beauty. In addition, the chin is often seen as an external sign to judge a person’s personality. For example, a receding chin is often considered a symbol of timidity and indecisiveness, while a person with a well-defined, slightly forward chin is considered to be brave and resolute. If we compare the face to an article, then the chin is like the closing paragraph of the article, and a good closing will give people a sense of clarity and delight. Therefore, nowadays, many people will choose to adjust the chin, which has the most profound effect on the facial contour, through cosmetic surgery. However, do you know how long the different materials for chin pads can be maintained? The current materials used to pad the chin can be broadly divided into: silicone, tumescent, hyaluronic acid, collagen, autologous fat, different materials to maintain the time is different. 1, silicone once successful can be retained permanently, if there is no serious improper location and rejection are not required to remove. However, the general requirement of silicone materials implanted in the body 10 years later, we need to conduct regular checks, if there are problems need to be removed in a timely manner. 2, tumescent tumescent material is not easy to rejection reactions, and the combination of solid autologous tissue, after placement is not easy to move and displacement, can be maintained for 10 years or more. However, this material is prone to infection and requires regular inspection. In addition, the expansion of the chin may have shrunk over time, once the emergence of the situation should be taken seriously. 3, hyaluronic acid Hyaluronic acid has the characteristic of being easily absorbed by the body, and the maintenance period is about 6 to 9 months, after which it needs to be injected again. However, hyaluronic acid chin augmentation is less traumatic and recovery is faster. Within 24 hours after the injection, try to minimize touching or impact to prevent the chin from being deformed. There will be slight redness, swelling and itching after the injection. In addition, it may feel a little hard after injection, which is normal and will generally soften after two weeks. 4, collagen collagen will pass with time, the older you are, the more you can’t stay, the effect lasts for a few months or even a year for reasons such as personal maintenance. Collagen is a must-have in the human body and is very compatible and does not produce any rejection reactions. After the injection, there will be a mild swelling period, which will naturally subside in about 3 to 10 days depending on individual body differences. 2 to 3 weeks later, the collagen will be very natural after it dissolves with the chin tissue. 5. Autologous fat Autologous fat transplantation has an absorption rate of about 30-70%. The results depend very much on the personal experience of the doctor, but no experienced doctor can guarantee 100% that the client will get the desired results in just one session, and some people may have to have 2 to 3 sessions to get satisfactory results. The transplanted fat is similar to normal fat, and after 6 months, it basically proves to be permanently viable.
