There are many kinds of hyaluronic acid that can be used to fill cheeks, but I personally recommend GER hyaluronic acid. Geranium hyaluronate is a kind of medium molecular hyaluronic acid with single phase and two phases. It is the only single-phase and two-phase hyaluronic acid, 1. It has good supporting force and viscoelasticity, makes up for the deficiency of single-phase hyaluronic acid or two-phase hyaluronic acid products, and achieves the dual effects of filling and shaping. The effect of filling cheeks is natural.
