How do supplements in cosmetics work on the skin?

The sale of cosmetics (camouflage or for daily care) is always associated with the mention in their composition of useful active dietary supplements: vitamins, microelements, natural organic acids, structural components similar to natural skin elements, water components. How effective are such substances in the composition of cosmetics, and how do they affect the quality of the skin?

The ability to ingest vitamins and trace elements in order for the body to digest and use these substances to restore the health of various organs and tissues is understandable, but the mechanism for the intake of similar nutrients for their intended purpose when used externally raises justified questions.

The skin is a complete organ capable of absorbing and releasing chemicals. Thanks to these functions of the skin, many substances can be used externally, so that, bypassing the general blood flow and not having any effect on other internal organs and tissues in the body, the skin can receive the substances it needs. These functions of the skin are used to treat superficial focal diseases, for a point effect on certain areas of the body adjacent to the skin closely for medical purposes.

When it comes to cosmetics and its effective impact on the skin, the same mechanism for delivering nutrients to the destination is used to restore and correct minor cosmetic external skin defects, to restore subcutaneous elements that require biochemical support.

Vitamin groups that have a beneficial effect on the composition and structure of the skin in an even more effective form can be used in creams, ointments, lotions, applications, masks.

The most important vitamins for the skin are B vitamins, vitamin A, vitamin E, vitamin D. These vitamins can be delivered directly to specific areas of the skin and subcutaneous tissue through a system of capillaries that penetrate the entire skin and nourish the skin.

Vitamin A in the composition of an external cosmetic product has a regenerative effect on skin cells, restores damaged surfaces, forms new layers of cells that replace those lost as a result of injury or aging. Vitamin A is also responsible for metabolic processes in the skin, its amount directly affects the processes of keratinization of skin cells and their death. This vitamin inhibits keratinization processes and keeps the skin from premature aging.

Vitamins of group B play an important role in carbohydrate metabolism of skin cells, supply the skin with chemicals that keep metabolic processes at the level of health, correct disruptions in metabolic processes (in the cellular metabolism of the skin). This group of vitamins ensures the proper functioning of the sebaceous and sweat glands, allowing the cells of the skin and hair to remain strong, and restores their microstructure by nourishing if required.

Vitamin D is a building block of skin cells, which is responsible for the correct phosphorus, calcium and water metabolism in skin cells. Vitamin D controls skin turgor, its strength and elasticity.

Vitamin C, along with vitamin D, participates in the construction of collagen and elastin fibers in the skin, vitamin C is responsible for the permeability of skin capillaries, for their elasticity and mechanical endurance.

Vitamin E is the main antioxidant in intracellular biochemical reactions in the skin. Vitamin E helps vitamins A and B perform their biochemical functions.

Lipid complexes (mono- and triglycerides of fatty acids, natural and synthetic phospholipids) in cosmetics are designed to ensure the trophic function of the skin, to restore the cell membranes of skin cells. Lipid complexes are responsible for the superficial fatty layer on the epidermis, which performs a protective function for skin cells, preventing them from drying out and mechanical action of external environments on them.

The hormones that make up cosmetic creams, ointments, coming through the pores and the capillary system to the cells of various layers of the skin, have a healing and restorative effect on skin cells, they relieve inflammatory processes. Some hormones inhibit excessive hormonal activity in metabolic processes that regulate the metabolism of the skin. Hormonal components in creams, ointments and lotions have a regulating effect on lipid and carbohydrate metabolism.

An interesting role in the restoration of skin cells is played by protein structures (proteins), which are responsible for the species identity of skin cells, prevent the degeneration of epidermal cells into connective tissue cells, prevent atrophic changes in skin cells associated with both metabolic disorders and aging processes. oppression of biochemical reactions by various toxic substances from the external environment. Proteins in creams and ointments of cosmetic products also play a moisture-retaining function in skin cells.

Hydrolysates of elastin and collagen, which are part of a cosmetic product, are a group of amino acids that help to restore the destroyed chains of proteins that are part of collagen and elastin fibers.These supplements increase the absorption functions of the cell cover, restore and improve the quality characteristics of hair, giving it elasticity , elasticity and shine.

It is important that the components of cosmetics are water- or fat-soluble, otherwise the skin will not be able to absorb, transport and receive nutrients in the right place and in sufficient quantities. The components of cosmetics insoluble in water or fats are not absorbed into the skin, have only a superficial effect, for example, they can narrow the pores of the skin or cover the skin with a protective layer. Such substances from cosmetics do not enter the bloodstream and have the character of only an external camouflage covering of the defect. So decorative tonal creams do not participate in metabolic processes in the skin. Decorative lipsticks are not absorbed into the mucous membrane of the red border of the lips, protective creams have no other effect than a superficial protective effect, forming a layer on the surface of the skin, preventing the penetration of substances from the external environment into the thickness of the skin and into the skin cells.

It is important to adhere to the sequence of applying cosmetics to the skin for this reason: the first layer is always cosmetics with a therapeutic and prophylactic effect, with restorative effects according to the recipe of the cosmetic. Time is maintained until such cosmetics are almost completely absorbed into the skin, and only then protective cosmetics are applied. There are types of decorative cosmetics, the composition of which contains additives of vitamins or other useful substances, but such protective agents cannot be applied over protective and camouflage tonal creams, since substances that are properly absorbed into the open pores of the skin will not be able to achieve their purpose due to the opposition the protective layer of decorative cosmetics.

Such a specific effect of various cosmetics on the skin requires a competent approach not only to skin care, but also to decorating or camouflaging the skin.
