Imbalanced fat metabolism. The reason why the face becomes more collapsed after the Frozen Age Injection is because the metabolism of fat after the injection is imbalanced, resulting in uneven local skin. In addition, if the ingredients of the age-freezing injection are not completely absorbed, it will also cause bumps on the face, making the face look uneven. In addition, too much injection can strain the facial muscles, leading to facial collapse. When injecting frozen age injections, you should choose a formal institution to ensure injection safety.
