Vitamin C - ascorbic acid - detoxifies the body of some metabolites and seals the blood vessels. It acts as an antioxidant against free radicals in the aquatic environment of the cell interior and in intercellular fluids and in the capillaries of the skin.


Vitamin C fights free oxygen radicals

Vitamin C fights free oxygen radicals in the aqueous environment of the connective tissue of the skin and in the subcutaneous tissue, protecting the thin fibers of collagen and elastin from damage. As it is known, the "stroke" of toxic free radicals, associated with oxidative stress, damages the skin cord made of these fibers. Recall that vitamin C is also essential for the process of building and regeneration of fibrous connective tissue. It is advantageous to combine its action with the presence of another valuable antioxidant - a popular routine, which significantly prolongs its tissue activity.

To cover the skin against excess oxygen free radicals and against harmful intrinsic and extrinsic substances, vitamins A, E and C are most commonly used.

Vitamin C fights oxidative oxidative stress in the skin and soothes inflammation

It has been proven that the consumption of vitamin C grows rapidly under the influence of sunburn, when oxidative stress occurs in the skin, or "discharge" to the tissues of a large amount of free oxygen radicals. Therefore, it is obvious to recommend using the vitamin after a day of intense sunbathing, especially in the case of sunburns. It can be used both internally (orally) and externally (it is available in the form of numerous protective and regenerative preparations). It is necessary to know that oxidative stress also causes all inflammation of the skin - for example, associated with allergic urticaria, eczema, etc. It is also worth remembering that the outflow of free radicals causes surgical operations, as well as wounds or normal cuts. Vitamin C neutralizes excess free radicals as well as accelerates healing.


Seals circulation, detoxifies

Maintaining a proper level of vitamin supports the sealing of blood vessels, especially in the microcirculation and in protection against infections. In addition, vitamin C is easily associated with poisoning the body with heavy metals, as well as with harmful products of metabolism - neutralizing their toxic effects. It also neutralizes these toxic metabolites that are found in the body due to poor urine and faecal excretion. Well-cleaned of toxins, the body repays with healthy and more skin.

 
It is assumed that the daily oral dose of vitamin C should be 60-100 mg

An older person should take more vitamin C, especially if he drinks coffee, strong tea, smokes cigarettes, because the drugs consume excess of vitamin. In addition, the dose of vitamin C should be increased when we take acetylsalicylic acid (aspirin), because then it increases its excretion with urine three times. However, it should be remembered that the absorption of the vitamin dose is not absorbed 100%, but to a much lesser extent.

If we use a tablet with a prolonged release of ascorbic acid

A large dose will turn into a continuous supply of low-intensity vitamin - then the risk of urolithiasis decreases significantly. However, with documented increased excretion of urate and cystinnias in a given person. At high doses, there is a danger of kidney stones. Large doses may cause calcium oxalate to accumulate in the urinary tract.

Vitamin C is soluble in water and does not accumulate in the body

Excess vitamin 2-3 hours after being absorbed by the body is removed together with the urine. The condition for satisfying the needs is therefore a constant, continuous "delivery" of the vitamin. The absorption of synthetic vitamin C is not complete, it is assumed that the human body assimilates only the fifth part. It is excreted through the kidneys, slightly reduces the pH of the urine.


Vitamin C applied topically to the skin

Vitamin C applied on the skin (topical) - is a powerful antioxidant that prevents adverse subsurface changes associated with oxidative UV influence. For example, modern preparations containing stable vitamin C in the form of L-ascorbic acid protect against the oxidation of lipids and skin proteins. The topical action of this vitamin is particularly effective in preparations containing a very high, over 15% content of this ingredient. For example, the effect of ascorbic acid on the synthesis of collagen in artificial skin cultures has been described.


Vitamin C fights wrinkles

Based on many years of cosmetology practice, it was observed that a topically applied cream containing 5% vitamin C as L-ascorbic acid reduces the age-related changes in the epidermis, leading to the formation of the first wrinkles. These effects are related both to the beneficial effect of vitamin C on the connective tissue and its delicate exfoliating effect


Warning! Skin damage is difficult to regenerate

Proper protection of the skin against external factors, especially against ultraviolet radiation should be carried out from childhood. Only then can you reduce the symptoms of skin aging by up to 80%. - claims in his speeches a well-known specialist prof. dr hab. med. Sławomir Majewski, dermatologist, head of the Institute of Venereology, Medical University of Warsaw. Therefore, the skin should be protected from the sun from an early age and preventive measures - including cosmetics with filters to counteract ultraviolet radiation and free radicals. It should be remembered that damage of this type is difficult to regenerate, and it easily accumulates and accumulates.
