It is said that vitamin C can whiten, what is the principle?

Can vitamin C really whiten.

Vitamin C has a certain whitening effect, and the whitening ingredients it contains are also relatively safe and effective, vitamin C, also known as ascorbic acid, can play a good role in antioxidant and anti-aging, and can also heal the ability to maintain cell integrity, so it can place scurvy and the like, then its beauty effect is also very powerful, which can interfere with the formation of melanin, so as to make the skin more shiny.

The principle of vitamin C whitening is that vitamin C can reduce the synthesis of melanin such as dopaquinone and interfere with the production of melanin by interacting with the active site of copper ions in tyrosinase, which has the effect of whitening and antioxidant.

In fact, it is accurate to say that vitamin C does not play a role in whitening, because it has a good antioxidant effect, and he can inhibit the growth of melanin. Reduce UV damage to **. So as to play a whitening role.

Because it is made up of antioxidant and anti-free radicals and inhibits tyrosinase formation. It hinders the synthesis of melanin, so it achieves a whitening effect.

1. It has a certain whitening effect.

Vitamin C, also known as vitamin, is a polyhydroxyl compound, similar to glucose in structure, mainly formed by antibodies and collagen, is a highly effective antioxidant, can help lighten the body's melanin, improve the human body's dullness, pigmentation and other phenomena, has a good whitening effect, so vitamin C in life is a certain whitening effect.

2 It depends. To sum up, it can be known that vitamin C does have a certain effect on promoting whitening, but whether taking one tablet a day can whiten depends on the actual situation of the individual.

Because everyone's imitation skin color and the degree of absorption of vitamin C is different, some people are relatively white, and they can be effective quickly after eating vitamin C, and some people are born with darker complexions, plus the absorption of vitamin C is not very good, so the effect is not very good, so whether a tablet of vitamin C can be whitened every day needs to be determined according to individual circumstances.

3 is also possible.

Vitamin C can be used externally for whitening, because vitamin C has good antioxidant properties, and external application can help remove free radicals in the body, which can help lighten the melanin in the human body, and can make the human body's ** delicate and smooth, so as to play a certain whitening effect, so the external application of vitamin C also has a certain whitening effect.

4 The details are as follows:

1. Promote the formation of antibodies; High concentrations of vitamin C help reduce cystine in food proteins to cysteine, which in turn leads to the synthesis of antibodies.

2. Promote iron absorption; Vitamin C promotes iron absorption by reducing hard-to-absorb ferric iron to easily absorbed ferric iron. In addition, it can also make the sulfhydryl group of ferrous complexase in an active state in order to play an effective role, so vitamin C is an important auxiliary drug for anemia.

3. Promote the formation of tetrahydrotropic acid; Vitamin C can promote the reduction of folic acid to tetrahydrofolate, so it also has a certain effect on megaloblastic anemia.

4. Detoxification; After supplementing a large amount of vitamin C in the body, it can alleviate the toxic effects of heavy metals such as lead, mercury, cadmium, and arsenic on the body.

Vitamin C, also known as ascorbic acid, is an acidic polyhydroxy compound containing 6 carbon atoms, with the molecular formula C6H8O6 and a molecular weight of 176.

Vitamin C is an essential nutrient for higher primates and a few other organisms. Ascorbic acid can be produced by metabolism in most organisms, with the most notable exception in humans. It is best known that vitamin C deficiency can cause scurvy.

In living organisms, vitamin C is an antioxidant that protects the body from the threat of free radicals, and vitamin C is also a coenzyme. Its wide range of foods** consists of a variety of fresh fruits and vegetables.

There are two types of naturally occurring ascorbic acid, L and D, the latter of which is not biologically active. Vitamin C is a colorless and odorless flake crystal that is easily soluble in water and insoluble in organic solvents. It is stable in an acidic environment, and can promote oxidative damage when it encounters oxygen, heat, light, and alkaline substances in the air, especially in the presence of oxidase and trace copper, iron and other metal ions.

Oxidase is generally more abundant in vegetables, so vegetables are lost to varying degrees during storage. However, the bioflavonoids contained in some fruits can protect their stability.

Function: Vitamin C is necessary for the formation of antibodies and collagen, tissue repair (including some redox effects), the metabolism of phenylalanine, tyrosine and folic acid, the utilization of iron and carbohydrates, the synthesis of fat and protein, the maintenance of immune function, hydroxylation and serotonin, the integrity of blood vessels, and the promotion of non-heme iron absorption.

The principle that vitamin C can be whitened!

The iodine solution is reddish-brown, the vitamin C solution is light white, and the mixed solution becomes colorless. Vitamin C, also known as ascorbic acid, is an acidic polyhydroxyl compound containing 6 carbon atoms and is white in color. The iodine in iodine wine has strong oxidizing properties, while vitamin C is reducing, and the two can undergo redox reactions and produce pale yellow and white substances, respectively.

1.Vitamin C whitens the skin.

Because it can help protect the skin from UV rays and avoid dark spots and freckles, many whitening products are added with vitamin C, which is believed to be extremely effective in whitening.

In summer, it can prevent skin damage after sun exposure, promote metabolism, let the formed melanin be discharged, and lighten spots.

In autumn and winter, it can change the dullness of the skin due to poor blood circulation.

It can also help the skin lock in the necessary moisture, avoid peeling and tightness caused by excessive evaporation, strengthen the skin's ability to resist external pollution, and avoid tiredness, sallow and unsightly.

2.Vitamin C can eliminate acne.

Vitamin C is easily oxidized and not easy to preserve, so it is quite limited in the use of skin care products. Nowadays, the vitamin C in many skin care products has been chemically treated, so that they are not susceptible to loss, and can also enhance the penetration of **, and then destroy the synthesis of melanin, so that it can exert a whitening effect.

Emulsions containing vitamin C can directly penetrate the skin to repair damage and aging caused by ultraviolet rays, so it can whiten the skin and reduce fine lines and dark spots.

Because it can improve the effect of acne, whitening, etc., recently, high concentration of vitamin C is often used on **.

3.Vitamin C removes melanin.

**The color depends mainly on the amount of melanin in the skin. The root cause of melanin production lies in tyrosinase. The tyrosine in melanocytes is converted into dopaquinone under its action, and then oxidized to form eumelanin, which gradually reaches the surface of the skin with the normal metabolism of the skin, and finally naturally peels off with the aging keratin.

If the skin metabolism is not smooth, it will lead to a large amount of pigmentation and local accumulation, and the color will deepen or form spots and cause uneven skin. Therefore, inhibition of tyrosinase biosynthesis and sun protection are the keys to whitening.

Vitamin C, also known as ascorbic acid, was originally used for scurvy.

It cannot be whitened, and even if it has a cosmetic effect, it is not obvious.

Main features:1Promote the biosynthesis of bone collagen, which is conducive to the faster healing of tissue wounds;

2.prevention of cardiovascular disease;

3.Promote the growth of teeth and bones, prevent gum bleeding;

4.**Scurvy;

5.Cancer prevention. New clinical uses:

1.**Hand peeling (2ml dilution of vitamin C injection, or dissolved liquid in tablets for hand washing);

2.Uncomplicated stomatitis.

Suitable for: 1People who get tired easily;

2.people who live or work in a polluting environment;

3.People who smoke regularly;

4.People who engage in strenuous exercise and high-intensity work;

5.scurvy;

6.People with pigmented spots on their faces;

7.People who have been taking medication for a long time;

8.Cataract patients.

Vitamin C is a water-soluble vitamin, and excessive consumption can be excreted from the body with the body's metabolism without causing harm.

In terms of health care, in fact, the effect of vitamin B is much better than vitamin C, which is also a water-soluble vitamin, so you can try to supplement it as appropriate.

Of course, eating vitamin C can whiten, and you can choose some fruits that contain more vitamin C.

Can vitamin C really whiten?

Are you the pill-like one?

It seems to say that the human body cannot absorb it

It seems that you should take health supplements

Something like Amway

It's quite expensive, though

It's better to eat more fruits

Vitamin C can be whitened

However, if you eat too much, you will be poisoned

It is best to take the medicine according to the dosage

I heard that vitamin E is good for **.
