If you want your skin to be pretty, moisturize first! http://www.cosmeticrawmaterial.cn/
1. Squalane
Squalane was originally extracted from sharks, and for environmental protection considerations, many of them are currently extracted from vegetable oils. It has been proved to be a lipid closest to human sebum, with strong affinity, and can be integrated with human's own water and sebum membrane, effectively forming a natural protective film, helping the balance between skin and sebum to achieve water and oil balance. And it is very effective against oxidation. Not only that, because pure squalane does not breed bacteria, it has a certain inhibitory effect on mold, so it can also play an anti-inflammatory role, and the feeling of use is refreshing and not greasy.
2. Hyaluronic acid
Hyaluronic acid, also known as hyaluronic acid and uronic acid, belongs to a skin conditioner, which naturally exists in the corneal skin and can absorb 1000 times its own weight of water, hundreds of times the water absorption capacity of glycerin, so by supplemting the lack of hyaluronic acid inside the skin, it can retain skin water, prevent water loss through the epidermis, and repair the barrier of damaged skin. In addition, together with other mucopolysaccharides, collagen and elastin, it can form an extracellular gelatinous matrix containing a lot of water, so as to make the skin more tender and elastic.
3. Ceramide
Ceramide, also known as molecular nail or Cylome, accounts for about 40%-50% of the intercellular lipids in the stratum corneum. Its hydrophilic and oil-philic properties enable it to form a unique lipid bilayer structure. The hydrophilic end strengthens water absorption, the oil-philic end maintains the slightly acidic seboradia membrane, strengthens the skin's defense, prevents bacterial invasion, maintains the normal metabolism of keratin, and tightly holds the water in the stratum corneum. Considering that ceramide will be lost with age, older students can choose ceramide and hyaluronic acid as hydration ingredients.
4. Beta-glucan
5. Soluble collagen
Soluble collagen is a non-hydrolyzed primary protein derived from the connective tissue of young animals. When used as an active substance in cosmetics, it can spread to the deep layer of the skin. The tyrosine contained in it competes with the tyrosine in the skin to bind to the catalytic center of tyrosinase, thus inhibiting the production of melanin, enhancing the activity of collagen in the skin, maintaining the moisture of the stratum corneum and the integrity of the fiber structure, and promoting the metabolism of the skin tissue. It has a good moisturizing and moisturizing effect on the skin.
6.PCA sodium
Sodium PCA, also known as sodium pyrrolidone carboxylate, is a humectant that occurs naturally in human skin and is the main component in the stratum corneum of the skin. It has strong moisturizing properties and is an amino acid derivative. In addition, PCA sodium has a high water absorption capacity and can absorb water from the air, which is comparable to hyaluronic acid, and is far stronger than glycerin, propylene glycol, sorbitol and other moisturizers. It itself is a transparent, colorless, odorless, slightly salty liquid, and can combine water with cells to grasp several times its own weight in water.
