Biotin has many different names, each of which gives an idea of the value of this substance for the human body. It is called vitamin H – from the German phrase Haar und Haut, which means "skin and hair"; and explains the special value for them of this bioactive substance. Another name for this substance – vitamin B7. Referring it to vitamins demonstrates the vital importance of this element for us. Coenzyme R – it is also biotin, a coenzyme, without which fats and proteins are not absorbed, ascorbic acid. Estet-portal.com notes that biotin is of interest to cosmetologists, first of all, as a vital element that maintains skin health.
The biochemical role of vitamin H in maintaining the health of the body
Biotin belongs to the water-soluble vitamins of group B. The substance is vital for the human body, since it acts as a cofactor in the synthesis of the glucokinase enzyme necessary for carbohydrate metabolism, and also participates in the regulation of fat and protein balance.
Among other important functions of biotin:
• necessary for the biosynthesis of saturated fatty acids;
• Needed for the synthesis of purine nucleotides – structural elements of nucleic acids;
• becomes a source of sulfur for cells, without which collagen synthesis is impossible;
• protects the nervous system from overexcitation;
• supports the growth and renewal of muscle and nerve cells;
• takes part in the release of energy from fats;
•
Vitamin H – an important element for maintaining healthy hair and youthful skin
Vitamin H is active in the processes of splitting fats and their assimilation by body cells. If it is not enough, the hair and skin immediately react. After all, fatty acids and other lipids, which form the basis of the protective mantle, cease to flow to them. In this case, the lipid balance is disturbed, and the skin can no longer protect itself.
The lack of biotin in the body quickly manifests itself in the form of a red rash on the face, constant peeling and itching of the skin.
The most noticeable and noticeable rash is in the corners of the eyes, around the mouth, wings of the nose. The skin becomes thinner and becomes dull, dry. Skin itching is accompanied by a burning sensation and tingling, because a lack of vitamin H impairs the functioning of the nervous system.
It is important to remember about the participation of biotin in the complex processes of glucose uptake, while it prevents glycation - a process that disrupts the structure of collagen and elastin fibers. A lack of vitamin H is manifested by rapidly developing flabbiness of the skin.

The exact mechanism of how biotin affects hair color has not yet been studied. But with a strong lack of this substance, the hair quickly turns gray. At the same time, scientists noticed that the appointment of biotin in this case helps to slow down the appearance of gray hair. In addition, this substance is necessary to maintain the molecular structure of keratin, balancing its chains and preventing hair breakage.
From the point of view of cosmetology, the ability of vitamin H to enhance tissue regeneration and accelerate healing processes is of particular value. Therefore, products with biotin are recommended, first of all, after traumatic cosmetic procedures, during the recovery period after plastic surgery. For home care, cosmetics with biotin are prescribed for sensitive skin, so that recovery after procedures is faster.
The ability of biotin to enhance cell renewal and restore the protective properties of the stratum corneum of the skin is used in cosmetics to combat signs of age-related changes.
Vitamin H is added to thinning hair products to prevent hair loss, as well as to cosmetics to combat early gray hair.
