There are two main factors that determine whether or not the phalangeal filler will shift afterwards: First, the filling substance. If the molecular quality of the filled hyaluronic acid is smaller than small, softer and poorer at the same time, it is possible for the hyaluronic acid to shift. Because within a week, that is, when the hyaluronic acid has not yet fused with the tissue, because the molecular mass is relatively small, it is easy to move the hyaluronic acid into the surrounding tissues when you rub or massage yourself, that is, displacement. Secondly, if the doctor’s technique is average, when filling to the outside of the decrescent lines, the decrescent lines will not only not be solved, but also deepen, and the hyaluronic acid will also be displaced to other locations. Whether hyaluronic acid is displaced or not depends on the product chosen. If you choose a better hyaluronic acid with a larger molecular quality, it will not be displaced in general. If the molecular quality is small, the hyaluronic acid is poor, and the doctor’s technique is not good, it is possible to displace.
