1. Formation of photoreceptor cells in visual sink cells.
Biotin is oxidized in the body to form cis-retinal and trans-retinal. There are two types of photoreceptor cells in the human retina, among which rod cells are sensitive to low light and are associated with scotopic vision because rod cells contain rhodopsin, which consists of opsin cells and cis retina. When vitamin H is deficient, the cis retina cannot be adequately replenished, and the rod cells cannot synthesize enough rhodopsin, resulting in night blindness.
2. Maintain the integrity and soundness of the epithelial tissue structure.
Biotin is an essential substance for maintaining the integrity of human epithelial tissue. When vitamin H is deficient, it can cause keratinization, hyperplasia and dryness of the mucous membranes and epidermis, resulting in dry eye syndrome. When the sebaceous and sweat glands become keratinized, the skin becomes dry, follicular papules and hair loss appear. Infections are prone to occur due to poor organization of the epithelial cells of the digestive tract, respiratory tract, and urinary tract.
3. Enhance the body's immune response and resistance.
Biotin can enhance the body's immune response and anti-infection ability, stabilize the lysosomal membrane of normal tissues, maintain the body's humoral and cellular immunity, and affect the secretion of a series of cytokines. Large doses can promote thymus hyperplasia, such as combined with immune enhancers, can enhance immunity.
4. Maintain normal growth and development.
When biotin is deficient, reproductive function declines, skeletal development is poor, and embryonic and young child growth and development are stunted.
5. When used in cosmetics, it can improve the blood circulation rate in the blood vessels of the skin.
In the concentration range of 0.1%~1.0%, biotin is easy to mix with the grease in the formula. Can be used in skin creams, sports lotions, foot pain creams, shaving creams, shampoos, etc.
