Joyaden Yan Feng is a product specially made for facial contour, which may mean that it has a unique advantage in contour enhancement. Its composition contains macromolecular hyaluronic acid, which is beneficial to the improvement of contour.
Although Tongyanzhen is also a filling product, it does not contain macromolecular hyaluronic acid, so it may not be as effective as Joyaden Yan Feng in contour improvement.
Generally speaking, if you want to improve the contour by hyaluronic acid, Joarden Yan Feng is a good choice, because it contains hyaluronic acid, which has a direct effect on contour improvement. However, everyone's situation is different, and it is necessary to choose the right product according to the individual's facial conditions and needs. The above information is for reference only. It is recommended to consult a professional doctor to determine the most appropriate treatment plan.
