On the goods of mass and individual cosmetics with vitamin A you can find: first age signs or regenerating, ritinol or carotene.
B vitamins contribute to skin rejuvenation:
B1 (thiamine) normalizes and supports metabolic processes in the skin, hair and nails, a necessary component of the regeneration and construction of new cells, ensures heredity at the cellular level;
B2 (riboflavin) stimulates energy processes in cells
B5 (pantothenic acid) prevents premature wrinkles
B6 (pyridoxine) activates metabolic processes
B12 (cyanocobalamin) helps the circulatory system and maintain weight normally
B1 deficiency in the body is reported by symptoms described in medicine, such as beriberi syndrome: decreased appetite, blurred consciousness, decreased muscle and intestinal tone, poor coordination, depression, weakness, nervousness, insensitivity, burning and / or swelling on the hands and feet, reduced pain threshold, shortness of breath.

Pantothenic acid is destroyed by dry heat, when the pH is deflected towards acid or alkali – in the oven or in the grill, by solutions of acids and alkalis, when canning and freezing, and when grinding (grinding grain), calcination (oils), refining sugar.
Vitamin B6 (pyridoxine)
is necessary in the processes of cholesterol metabolism and other metabolic processes, the formation of hemoglobin, for the functioning of brain cells.
It is recommended to increase the consumption of B6 during pregnancy, tobacco smoking, excessive enthusiasm for alcohol, with an increase in protein intake.
For a number of diseases, it is necessary to consult a doctor about the compatibility of B6 and prescribed drugs.

Vitamin C (ascorbic acid)the main functions of
the vitamin in the body are strengthening the walls of blood vessels and increasing immunity.

The skin contains an inactive substance that, under the influence of sunlight, in case of vitamin D deficiency, is converted into active vitamin D. This form is designated D3 and is also found in animal products. The amount of cholecalciferol synthesized in the skin under the influence of sunlight is affected by the length of the light wave, the color of the skin, the darker the skin, the less vitamin D in it is reserved, the purity of the atmosphere.
Synthetic vitamin D, designated as D2 (ergocalciferol), is obtained by exposure to ultraviolet radiation on some yeast fungi.

In cosmetics, suppliers of vitamin E: grape seed oil, shea olives, wheat germ or soybeans.
Vitamin PP (nicotinic acid, niacin) improves
the hematopoietic functions of the body, improves the digestive system, promotes skin smoothness, affects cholesterol metabolism, cell respiration, energy production during the oxidation of proteins and carbohydrates in cells. Reglulates higher nervous activity.
Vitamin is found in significant quantities in the kidneys and liver of animals, meat products, mushrooms, rye and wheat bread of coarse grinding, buckwheat, peas, sprouted grains, potatoes, cabbage, carrots, plums, grapes, apples and brewer's yeast.
