Also called Niacin, vitamin PP (or B3) is a water-soluble compound which, due to its structure and functional characteristics, is unable to accumulate in the body and which therefore must be introduced from the outside.
Its fundamental role in numerous physiological processes is mainly connected to the oxygenation of the tissues and therefore to the health of the skin.
Properties of Vitamin PP on the skin
The antioxidant action of vitamin PP counteracts the formation of free radicals which are among the main causes of skin aging .
Free radicals are oxygen molecules which, having lost an electron, are extremely reactive and tend to trigger numerous harmful chemical reactions.
They are in fact capable of damaging the cells producing collagen and hyaluronic acid, necessary to maintain correct cellular hydration and therefore the physiological tonicity and epidermal elasticity.
Their production is encouraged by various factors, including exposure to ultraviolet radiation, contact with polluting agents and the use of cosmetics unsuitable for your skin type.
The skin apparatus activates a series of antioxidant systems, usually enzymatic, which are not always effective enough.
In these cases, the use of vitamin PP-based creams proves to be a significant support for minimizing the aging processes.
- The ability to improve vascular function at the microcirculation level is due to the increased supply of oxygen; as a consequence the more oxygenated blood can release a greater quantity of this molecule to the tissues.
Its capillary protective action is concretized with an improvement at the structural level of the walls of the small blood vessels, making them more resistant, less permeable to the exchange of substances and therefore functionally regenerated.
- The control over the metabolism of carbohydrates and lipids made by niacin is particularly important for keeping the hydro-lipid film intact , which performs an indispensable protective function on the integumentary system.
The hydrolipidic film is an epidermal coating layer formed by a fat-soluble component (sebum), epidermal lipids and a hydrophilic fraction.
Its activities are linked to the control of the evaporation of water from the skin surface: when the film is not intact or malfunctioning, the cells are led to lose a high percentage of water, becoming dehydrated.
- Being endowed with a remarkable detoxifying power , when there is a continuous use of drugs that trigger cell aging processes, vitamin PP is able to stimulates the elimination of endogenous toxins, responsible for the loss of epidermal elasticity.
Toxins are harmful substances to the organism, whose mechanism of action takes place mainly on the skin as the skin cells are literally stormed by these compounds that accumulate over time.
If they are not eliminated effectively, their permanence can cause a progressive deterioration of the cell membrane with leakage of intracellular liquid.
The skin therefore tends to dehydrate, losing firmness and tonicity.
Action of vitamin PP on skin blemishes
Vitamin PP is not only useful for improving the aesthetic appearance of the skin, but it proves to be a fundamental ally for treating and preventing numerous skin imperfections.
- Its anti-acne activity is connected to the control of exchanges through the cell membrane; in fact this disorder, although having a multifactorial matrix, depends above all on an alteration in the production of sebum.
When the sebum is not eliminated physiologically, but tends to accumulate in the duct of the sebaceous glands located abundantly on the epidermis, the conditions are created for the onset of pimples and acne pimples.
Vitamin PP which, as is known, controls lipid metabolism in the skin, helps to avoid these harmful accumulations of sebum, slowing (or even eliminating) the formation of acne.
- In case of redness, irritation and swelling localized on the skin, the etiology of which depends on functional alterations of the microcirculation, niacin proves to be very effective because, by improving the vascular function, it eliminates these imperfections.
Even in the case of sunburn or caused by contact with allergenic substances, the preparations based on vitamin PP contribute to visibly improve the appearance of the skin.
- In all cases in which there are dyschromies and modifications of the compactness of the epidermis, which appears exaggeratedly relaxed, dull and without tone, the topical application of cosmetic products based of vitamin PP quickly improves the appearance of the skin.
After the use of aggressive cosmetic products that in any way have changed the appearance of the skin apparatus, the use of creams containing niacin is able to improve the aesthetics of the skin.
