Some candidates are worried that when they have tear trough filler, will it lead to the enlargement of bags under their eyes? As a doctor, generally speaking, this is not true. As we age, the skin will become more and more saggy and the tear trough will become deeper and deeper after the fat is displaced, and some candidates will have dark circles under their eyes, making them look very old and uninspired. In fact, many candidates have eye bags, but they are not obvious. In the case of mild eye bags, tear trough filler can solve the problem, not necessarily choose eye bag surgery. As for the filling material, I usually recommend autologous fat, followed by collagen, and then hyaluronic acid. It should be pointed out that hyaluronic acid is not suitable for those who have dark circles under their eyes, or those who have very thin skin. Because hyaluronic acid is a colorless and transparent material, it will form the Tindal phenomenon, and after the injection, it will appear that the local bruising is very obvious, which has a great impact on the appearance, and I personally do not recommend it. Will tear trough injections form bags under the eyes? Generally, no, unless the injection is too much or not injected to the correct location, which may lead to the problem of aggravating the bags under the eyes. For example, tear trough fillers need to be injected under the skin and on the periosteum, if there is a problem with the location or too much filler, or if the force is too great and it breaks through the orbital septum and hits the eye bags, the bags may be aggravated, but this situation rarely occurs, so there is no need to worry excessively.
