Description
Formulated with 73% Collagen and 8 kinds of Hyaluronic Acid, the serum helps to hydrate and reduce skin’s aging and fatigue signs.
The serum contains about 500 dalton of ultra-low molecular collagen that can penetrate into the skin. What does “500 dalton” means? Dalton is a unit that shows the unit of molecular weight. By the widely known “Law of 500 Dalton”, only ingredients less than 500 Dalton can be easily absorbed into the skin. Unlike the collagen normal molecular weight of about 300,000 Dalton, the collagen in Numbuzin No.4 serum used 500 Dalton of finely divided collagen for better absorption!
