First, keep the difference in length of time.
Small molecular hyaluronic acid has a short retention time in human body; High molecular hyaluronic acid has a long storage time.
Second, the effect difference
Hyaluronic acid, a small molecule, has the functions of moisturizing, lubricating and preventing the diffusion of tissue fluid. High molecular hyaluronic acid can play a role in filling, shaping and anti-aging.
Third, the differences between applications.
Hyaluronic acid is a kind of hyaluronic acid molecule like water, which is mainly used for injection into the dermis of the whole face. Replenish the lack of moisture in dermis, repair damaged skin, moisturize and rejuvenate skin, and make up for the deficiency of macromolecular and mesomolecular hyaluronic acid.
Polymer hyaluronic acid is mainly used for breast augmentation, buttock augmentation, nose augmentation, chin augmentation and other plastic surgery, and the filling site is deep tissue. High molecular hyaluronic acid can also be used to remove wrinkles. Hyaluronic acid is injected as a filler into the folds and depressions of dermis or the parts to be enriched.
