Hyaluronic acid is a natural biological substance that widely exists in the vitreous body, skin, umbilical cord, synovial fluid and other tissues.
The early hyaluronic acid raw materials were mainly separated and extracted from cockscombs, so they were not further promoted due to the limitation of cost and raw materials.sodium hyaluronate skincare,
The current hyaluronic acid is mainly produced by microbial fermentation, which is not limited by animal raw materials, has low cost, is easy to produce on a large scale, and has high product purity.sodium hyaluronate skincare,
The main roles of hyaluronic acid in cosmetics are as follows.
moisturizing effect
Compared with other commonly used moisturizing agents, hyaluronic acid is a natural substance inherent in the body, with less side effects and less influence by environmental humidity.
Nutritional effect
Hyaluronic acid is a natural substance inherent in the skin and other tissues, which can penetrate into the epidermis of the skin, which is conducive to the supply of nutrients and the discharge of metabolites, preventing skin aging and nourishing the skin.
Repair
Hyaluronic acid is used in combination with other ingredients to accelerate the regeneration of epidermal cells and has a healing and repairing effect on damaged skin.
sun protection
Products containing hyaluronic acid can promote the proliferation and differentiation of epidermal cells, scavenge free radicals, repair skin burns caused by sun exposure, photosensitive dermatitis, skin reddening, darkening, peeling, etc.
Its mechanism of action is different from that of UV absorbers commonly used in sunscreens, and has a synergistic effect, which can simultaneously reduce UV transmission and repair UV-induced skin damage to achieve dual protection.sodium hyaluronate skincare,
