Glycerin
Glycerin has the best moisturizing effect and is a versatile moisturizer. It is usually made from oils and fats. Glycerin has strong hygroscopicity. Pure glycerin can absorb 40% of water, so it can form a film on the skin, which can insulate air and prevent moisture from evaporating. It can also absorb moisture in the air. Therefore, in winter, people often apply glycerin on the skin surface exposed to the air, such as hands and face, which can keep the skin, elastic without being damaged by dust and weather, etc., and play a role in preventing skin frostbite.
Amino acids
The amino acid composition is relatively mild and will not irritate the skin. It can also be used for sensitive skin. Moreover, the small molecular structure of amino acids is easier to be absorbed by the skin. It can regulate the moisture on the skin surface to a certain extent.
Hyaluronic aids
Hyaluronic acid is an existing molecule with a strong water absorption function in the world. It is the main component of connective tissues such as human intercellular substance, vitreous body, joint synovial fluid, etc. It plays an important physiological function in water retention, maintenance of extracellular space, regulation of osmotic pressure, lubrication, and promotion of cell repair in the body.
Natural moisturizing factor NMF
The source of NMF is pro keratin filaggrin through a series of processes to produce various components that makeup NMF. It can represent 20-30% of the dry mass of the stratum corneum. The importance of NMF lies in its chemical components, especially pyrrolidone carboxylic acid (PCA) and lactate, which have strong hygroscopicity. These salts absorb moisture in the atmosphere and dissolve in the water used for their hydration, thus acting as a moisturizer for the skin.
Hydrolyzed collagen
Hydrolyzed collagen is a more versatile whitening ingredient. It not only replenishes the amount of collagen in the body but also restores skin elasticity, restores firmness, reduces sagging, smooths fine lines and wrinkles, creates smooth hair, strengthens nails, and beautiful figure.
Ceramide
Ceramide is similar to the material that constitutes the stratum corneum of the skin. It can quickly penetrate the skin and combine with the water in the stratum corneum to form a network structure that locks in moisture. As age increases, the amount of ceramide in human skin will gradually decrease, and the appearance of skin abnormalities such as dry skin and rough skin is also due to the decrease in the amount of ceramide. Therefore, to prevent such skin abnormalities, supplementing with ceramide is an ideal way.
Plant extracts (such as seaweed, aloe, etc.)
Both aloe and seaweed are natural moisturizing factors, moisturizing formula from plants, you can boldly choose skincare products containing aloe and seaweed.
