Facial filler surgery is one of the more popular plastic surgery procedures. Some candidates with congenital facial defects, such as a narrower forehead, sunken temples, and collapsed apple muscle, can achieve a finishing touch with hyaluronic acid or fat fillers. If more parts need to be filled, the cost may be higher and there is a difference in the price of autologous fat filler and hyaluronic acid filler. Generally, autologous fat fillers are preferred. The disadvantage is that the recovery period is longer and swelling is more pronounced, but the results are more cost-effective and longer lasting than using artificial materials. If this method is used, a certain amount of fat is usually extracted from the thighs or abdomen, and after special processing, such as resting or centrifugation steps, the fat is processed into individual fat particles and filled with a syringe to the areas that need to be filled, such as the cheeks, temporal area, forehead, etc. Hyaluronic acid, on the other hand, is mainly used for the improvement of interbrow lines, nasolabial folds, and head-lift lines, but there is the problem of late absorption and repeated injections are required. At present, fat filler is more widely used, the filler belongs to autologous tissue, there is no problem of rejection, and it is cheaper than hyaluronic acid, and the filling effect is better.
