Hyaluronic acid (HA) is a straight chain macromolecular mucopolysaccharide composed Of repeat disaccharide units of glucuronic acid and N-acetylglucosamine. The commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid. Its molecular weight is from several ten thousand to several million. It's aqueous solution has outstanding moisture keeping ability, high viscoelasticity and lubricity. It is widely used in cosmetics, pharmacy and health and beauty food.

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
(1) <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.
(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. It can be used in eye surgeries including cataract removal, corneal transplantation, and repair of a detached retina and other eye injuries.
4. Injection Industry
We recommand Injection Grade for you. It can be made into HA filler used on our body, like face, lip, breast, etc.
