Hyaluronic acid can distinguish true from false. First of all, it depends on whether the product is produced by a regular manufacturer. Secondly, it depends on whether the product is safe and effective, and whether it has passed the examination and certification of the State Food and Drug Administration (CFDA). This is the premise and basis for us to choose the brand of hyaluronic acid. Secondly, choose the hyaluronic acid that suits you best. At present, hyaluronic acid products for injection on the market mainly exist in the form of gel particle suspension. Crosslinked hyaluronic acid is composed of cross-linked sodium hyaluronate and non-cross-linked sodium hyaluronate, which has the function of wrinkle removal and shaping. Non-cross-linked hyaluronic acid is mainly used to lock skin moisture and restore skin youthful vitality. Finally, choose doctors with legal injection qualifications and regular medical beauty institutions for injection.
