Zyrex Cosmetic Grade Hyaluronic Acid Powder Low Molecular Weight Pack of 100 Gram

Moisturising

Hyaluronic acid has a higher moisture absorption at lower relative humidity (30%) than the commonly used humectants sorbitol, propylene glycol, and sodium lactate. The longer molecular chains of hyaluronic acid are intertwined in a highly concentrated solution, forming a mesh structure that ultimately binds to water through hydrogen bonding. According to relevant research, the water retention value of hyaluronic acid can reach more than 500mL/g, with very significant hydrophilicity. Hyaluronic acid is an important asset for the skin to always maintain elasticity and hydration. However, with age, the content of hyaluronic acid in the skin gradually decreases, making the skin rough and less elastic.

Removal of Reactive Oxygen Species

External environmental influences such as UV irradiation, atmospheric pollution, and blue light radiation can cause skin keratinocytes to produce excessive reactive oxygen clusters ROS, which are mainly classified as superoxide radicals (O2–) and hydroxyl radicals (-OH). Excess ROS can lead to skin inflammation. Hyaluronic acid can fight against oxidative skin damage in multiple ways and pathways, so the use of products containing hyaluronic acid will have a soothing and soothing effect on the skin, the use of hyaluronic acid in conjunction with other soothing ingredients will help to alleviate skin sensitivity.

Reduces Transepidermal Water Loss

Hyaluronic acid, as a mucopolysaccharide, can be applied to the skin surface to form a dense and breathable water-locking film on the surface of the skin and absorb moisture from the air, preventing the evaporation of water inside the skin, reducing the rate of trans-epidermal water loss, enhancing the barrier function of the skin, and lowering the chances of inflammatory reactions.

Anti-Lipid Peroxidation

Lipid peroxidation is also a contributing factor to skin inflammation. The end product of lipid peroxidation, lipid peroxide, directly damages DNA molecules and promotes increased malondialdehyde levels in the body, leading to skin inflammation. Hyaluronic acid has been shown to significantly inhibit the effects of lipid peroxidation, much more so than VC.

Inhibition of Inflammatory Factors

Interleukins are cytokines produced by cells and transmitted to immune cells, which activate the immune cells to trigger an inflammatory response. High molecular weight hyaluronic acid powder significantly inhibits the expression and level of interleukins, thus reducing the adverse effects of interleukins on the skin.
