Hyaluronic acid is an acidic mucopolysaccharide macromolecule substance widely found in human and animal connective tissues. It has important functions in the body such as retaining water, regulating osmotic pressure, maintaining tissue morphology, as well as lubricating, diffusing barriers and buffering stress. From the age of 25, the hyaluronic acid in the human body will gradually lose, at the age of 30 only 65% of the young skin left, at the age of 50 only 25% of the young skin left, hyaluronic acid with the increase in age and loss of long term, the skin will gradually lose the elasticity, luster, aging, wrinkles and laxity will also arise.
LMW-HA has a small molecular size and low viscosity, which makes it easy to penetrate into the skin layer and tissue cells. It has moisturizing, antioxidant, and wound healing properties, and is commonly used in skin care products, moisturizing creams, face masks, and other cosmetics.
MMW-HA has high viscosity and water retention capacity, and can form colloidal substances with good water-absorbing and moisturizing effects. It is commonly used in skin care products, creams, serums and other products to provide long-lasting moisturizing effect and skin softness.
HMW-HA has a large molecular size and high viscosity, and is able to form a protective barrier on the surface of the skin, effectively preventing water loss and external environmental aggression. It is commonly used in skin care products, masks, eye creams and other products to provide moisturizing, nourishing and anti-aging effects.
Low molecular weight hyaluronic acid has many physiological functions and has a broad application prospect in pharmaceutical and cosmetic manufacturing. In the field of pharmaceutical manufacturing, low molecular weight hyaluronic acid has anti-inflammatory, promote cell repair and proliferation, anti-tumor, immunomodulation and other effects, and can be used in the manufacture of targeted drugs, anti-inflammatory drugs, ophthalmic drugs, etc.. In the field of cosmetic manufacturing, low molecular weight hyaluronic acid has the effects of antioxidant, water replenishment and moisturizing, and can be used in the manufacture of face creams, eye creams, and essences, etc..
Medium molecular weight hyaluronic acid is the most versatile, and can be used in cosmetics, pharmaceuticals, and health care products. The main function in cosmetics is moisturizing. It can form a breathable film on the surface of the skin, locking water, preventing water evaporation, and providing long-lasting moisturizing. In the medical cosmetic industry, medium molecule hyaluronic acid has both a certain supportive and filling effect. It is suitable for filling the tear trough, apple muscle, lines, etc. It can improve the texture and contour of the skin.
High molecular weight hyaluronic acid has better viscoelasticity, moisturizing properties, and functions such as inhibiting inflammatory reactions and lubrication, which can be used for ophthalmic surgical viscoelastic agents and intra-articular injection therapy. In cosmetics, it is an excellent moisturizer that forms a protective film on the surface of the skin and is not absorbed by the skin.
Hyaluronic acid has strong water absorption and water retention, which can be added to food to maintain the moisture of food, prevent it from drying and deterioration, and extend the shelf life of food. It can also improve the texture and taste of the food, increase the viscosity and smoothness of the food, make the food more delicate, soft and flexible, and improve the overall quality of the food. For example, adding hyaluronic acid to yogurt can make yogurt thicker and mellower; using it in jelly can make jelly more Q-bouncy and chewy.
Like in baked goods, such as bread, cake, etc., hyaluronic acid can keep the moisture of the product, making it more fluffy and moist, slowing down the aging speed of the bread, and prolonging the shelf life. For some food products that need to maintain freshness and taste, such as sliced fruits and meat products, hyaluronic acid can also play a good moisturizing effect, reduce water loss, and maintain the original flavor and texture of the food.
In beverages, hyaluronic acid can be used as a thickener and stabilizer to prevent precipitation and delamination of ingredients in the beverage, making the beverage more uniform and stable. For example, adding hyaluronic acid to some fruit juice drinks and tea drinks can improve the stability of the drinks and maintain the consistency of their appearance and taste.
In summary, the applications of hyaluronic acid of different molecular weights varies tremendously. The use of one or more types of hyaluronic acid with a product is mainly determined by the positioning of the product, not the more types the better. Factories have to choose hyaluronic acid raw materials with different molecular weights according to the required products.
