Glycerol and glycerol can be classified as natural moisturizing agents with mild texture and no skin allergies. But glycerin itself is only moisturizing without skin care function, so it works well for young and healthy skin. If the skin needs maintenance in many directions, it is necessary to use other effective ingredients and glycerin in the skin care products.
Collagen is important for skin care, but because of its large molecule, it can not be directly accepted by the skin. What really improves skin collagen content is the use of collagen enhancers, such as vitamin C, vitamin B3, vitamin A.
Hydrolyzed collagen is the treatment of large molecular collagen by means of hydrolysis into small molecular weight proteins. The hydrolyzed protein is not as effective as other moisturizing agents in the simple moisturizing effect, but it can improve the function of skin. When choosing to buy, make sure that the collagen in the care product is labeled "hydrolyzed collagen", which is the collagen that can be absorbed by the skin. Similar to hydrolytic collagen, elastin, wheat protein, oat protein and silk protein.
Pro vitamin B5
Vitamin B5 is a permeable moisturizer. After absorption by skin, it can directly infiltrate into the stratum corneum, increase the content of hyaluronic acid in the skin, and achieve the moisturizing effect. In addition, vitamin B5 has the function to help the skin tissue repair, stimulate cell division and regeneration and tissue repair, especially suitable for the use of mature skin, is a very popular ingredient in the maintenance products.
The moisturizing mechanism of amino acids is different from other moisturizers. It has no strong water absorption, but it has a regulating effect on the moisture content of the skin. As the content of water in the stratum corneum is reduced, the content of amino acids is reduced at the same time, so it is necessary to add the amino acid in the maintenance products to maintain the normalization of the horny function but the amino group. Acid does not belong to the "main moisturizing factor".
Hyaluronic acid, also known as a very strong water absorption, is an important mucus in the dermis, which can absorb water of hundreds of times its weight. It is called "high moisture content". But its excellent moisturizing function does not last for three years. In order to prolong its moisturizing effect, it is necessary to add grease emulsion to reduce the loss of moisture.
Natural moisturizing factor
The main ingredients of natural moisturizing factors are amino acids, sodium lactate, urea and so on. The simple moisturizing effect is not as good as glycerin, but because of its good skin affinity, it can adjust the skin acid and alkali function and maintain the normal operation of horniness. It not only has a moisturizing function, but also has a certain maintenance function, it is also an indispensable moisturizing component.
