As time passes, everyone’s face shrinks and hollows to varying degrees. At this time, we usually need something to add to fill in our face, tighten our face, generally in the country “these things” usually have two choices. One is hyaluronic acid, a 1ml; or autologous fat filling, from the stomach or legs after liposuction, after processing, the essence of the fat to fill the face. So how to choose between fat and hyaluronic acid? First of all, hyaluronic acid filling, the advantage is that the trauma is small, does not need a recovery period, the injection does not affect the work life, and the injection needle is very fine, the accuracy is very high. Especially for tear troughs, marionette lines and other small and precise locations, other things are irreplaceable. But the disadvantage is that the price is expensive, a small amount of injection can be, a large number of injections are expensive. And hyaluronic acid will be gradually absorbed, and need to be replenished at a later stage. Of course, the maintenance time of hyaluronic acid is much longer than we think, completely absorbed at least about two years, and even after two years of touching, in fact, there is still residual liquid is not absorbed it, and hyaluronic acid will stimulate a small amount of tissue proliferation. A small amount of injection for the nose, chin and other parts of the need for support also has its advantages. Besides, autologous fat, beauty advertisements say that the autologous tissue is not rejected, and a filler is effective for life. It looks attractive, but using autologous fat has its drawbacks. It is true that autologous fat filling will not be rejected, but autologous fat transplantation is a surgery, relatively traumatic, facial filler will be swollen, liposuction of the site should be pressurized bandage, but also to wear shapewear shaping. Moreover, the fat filling in the absorption rate is also very high, just filled especially full, but after three months now absorbed a lot of good can survive half, the older the vitality of the worse, the lower the survival rate, you may need two or even three times to fill in, in order to achieve the desired results. The advantage of autologous fat is that after three months of filling, the fat that survives is your own, and it will accompany you for life; if you are fat, it will be fat; if you are thin, it will be thin. On the whole, autologous fat filler and hyaluronic acid filler can play a very good effect, but have each other’s advantages and disadvantages. In terms of autologous filler, autologous fat is taken from oneself, there will be no allergy, rejection and other symptoms, and after the fat filler is finalized, the line is natural and the effect is relatively long-lasting. On the downside, dietary fat filling is a minimally invasive procedure that requires a one to two week recovery period to reduce swelling. Hyaluronic acid injection has no side effects on the human body, non-invasive and no recovery period, and the effect is obvious. However, after filling with hyaluronic acid, the effect will be maintained for a limited period of time, and it will be gradually metabolized after injection, requiring regular injections. It can be seen that hyaluronic acid and fat have their own advantages and disadvantages. If you need a small amount, and it is the forehead temple fat is not easy to survive the part, then the injection of hyaluronic acid; and if the amount of injection needs to be particularly large, hyaluronic acid cost is too high, even if the fat will be absorbed, the calculation is still fat grafting is better.
