Application

(1) Food Industry.

We recommand Food Grade with the Molecular Weight 800,000Da-1,200,000Da. It can be added into drinks, mink products, health care capsules, etc.

(2) Cosmetic Industry

There are kinds of Molecular Weight, which can be used into cosmetics products, like facial cleanser, mask, soap, lotion, shampoo, etc.

(a) <10,000Da (Super Low Molecular Weight):

Making hyaluronic acid smaller means it can reach a bit farther into skin’s uppermost layers for visibly enhanced results, so it has the best effect of moisturzing and anti-aging.

(b) 10,000Da-200,000Da (Low Molecular Weight)

It has better moisture effect than regular molecular weight.

(c) 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.

(d) >1,600,000Da (High Molecular Weight)

It can keep moisturing for longer time, and repair skins.
