2. Cosmetic Grade
(1) <6,000Da (Ultra Low Molecular Weight)
By far, this is the best hyaluronic acid found in facial serums and creams.
(2) <50,000Da (Low Molecular Weight)
Low molecular weight hyaluronic acid powder makes it possible to enter the skin and keep moisturing. The additional moisture not only makes the skin more firm and firmer, but also visibly reduces wrinkles.
(4) >500,000Da (High Molecular Weight)
High molecular weight hyaluronic acid powder can repair skins and keep moisturing for longer time.
