After stopping the hair hyaluronic acid, the face will have the symptoms of skin laxity and muscle sagging, and even wrinkles, and the skin will be red and swollen in serious cases. 3. If the injection of hyaluronic acid is used for face slimming, there is no very obvious change in the initial month after stopping the use of hyaluronic acid, but three months to six months after stopping the injection of hyaluronic acid, there is a possibility that the phenomenon of rebound will occur, and return to the original appearance of the original injection of hyaluronic acid before. 4.
