(2) 10,000Da-200,000Da (Low Molecular Weight) It has better moisture effect than regular molecular weight. (3) 200,000Da-1,600,000Da (Regular Molecular Weight) It can retain moisture, keep the skin firm, and prevent wrinkles by adding volume to the skin. (4) >1,600,000Da (High Molecular Weight) It can keep moisturing for longer time, and repair skins. 3. Eyedrop Industry We recommand Eyedrop Grade for you.
