The last time I talked about the myth about hyaluronic acid. Topic about the ingredients in cosmetics you like, so keep on her conduct.
Let's talk today about niacin (it is also called vitamin B3 or PP, nicotinic acid) And niacinamide.
This is such a component that does not need marketing. According to it, for many it was research, its effectiveness is proven. And in whatever form are niacin and niacinamide (capsules, gels, creams, lotions) - they will work.
Why so many names?
Indeed, in the composition of cosmetic and pharmaceutical agents can be found various names vitamin. The International Nomenclature of Cosmetic Ingredients (abbreviated - INCI) he is listed as Niacin.
But on the labels, sometimes, they write: vitamin PP, vitamin B3, Niacinamide and Nicotininc Acid (nicotinic acid).
I'll try to explain as easy as possible.
Different in structure - niacin and niacinamide.
We synonyms niacin - nicotinic acid, vitamin B3 and PP. Why are so many synonyms?
Austrian chemist Hugo Waydelich in 1873 with the help of nitric acid oxidation of nicotine received a new acid. I called her nicotinic acid.
Chemists have determined that the chemical compound belongs to the family of B-complex. And since it was discovered and attributed to Group B third - received V3 title.
It found that nicotinic acid works against pellagra - given the name vitamin PP. Pellagra - a disease that develops due to nicotinic acid deficiency in the body. It is very easy to remember for the "three D" symptoms - dermatitis, diarrhea, dementia.
So people are not confused with nicotine nicotinic acid and is not clocked up his mind about the benefits of smoking, it is necessary to somehow replace the name of the component that was not mentioned nicotine. It was decided to name niacin, and very strongly encourages the so-called nicotinic acid Association of American Physicians. I think this is a very good decision.
Niacinamide is synonymous with nicotinamide.
4 reasons why niacin and niacinamide are important for the body
If you move away from the topic of beauty, the vitamin B3, perhaps by its importance to human health can safely fight for first place between vitamin C and vitamin D. Without it, sugar, fats and other substances would lie in our body dead weight and transformed into energy. Convert food into energy - this is the main essence of vitamin B3.
The reason №1. From niacin formed NAD - molecules that cleave proteins, fats, carbohydrates, and even alcohol (so when the hangover is recommended to drink milk: there tryptophan, and he - the precursor B3 and B3 - the precursor of NAD).
From the NADP formed niacinamide. He just does not give off the energy of the substances, and vice versa - it consumes and produces complex molecules (eg, cholesterol).
So, OVER breaks and forms into energy, NADP - builds and restores using energy.
reason №2. Vitamin B3 breaks down all fats, which come from food, eicosanoids - biologically active substances that are involved in many processes: water-salt metabolism, regulate blood pressure, muscle tone, the state of the intestines, bronchi, uterus, and in many others. With a deficiency of vitamin B3 and the exchange of amino acids will be bad.
reason №3. Niacin as well dilates the blood vessels. Everyone who took niacin or causes the contents of the ampoules with him in person, knows how it strongly reddens in the first half hour. Cardiologists even prescribe this vitamin to patients suffering from cardiovascular diseases. And there are the medical facts that B3 helps qualitatively recover survivors of myocardial infarction.
reason №4. Vitamin B3 is capable of restoring DNA damaged cells.
Why skin vitamin B3
I have already said that vitamin B3 dilates blood vessels, and therefore - improves blood circulation. Where healthy blood flow - there is life.
There is a method of treatment of osteoarthritis using electrophoresis and niacin.
Property to expand the blood vessels in vitamin B3 has been taken over trichologist in the fight against hair loss. And Beauty too.
Deficiency of vitamin B3 for the skin - it is dry, strong sensitivity to ultraviolet (face quickly burns for an hour to find the active sun), uneven color. And if you run the whole thing, then close to itching, inflammation and even hair loss. Who is not convinced - I advise to look pellagrous symptoms of dermatitis immediately realize the importance of vitamin B3 for the skin.
Niacin is involved in the skin too much where it improves blood circulation, strengthens the walls of capillaries, and all this affects the production of collagen and elastin, and they have just decided - young or old, we to look like.
Our bodies can produce vitamin B3 itself, only with age, he produced longer and less.
What effect gives skin Vitamin B3
First, let me note a few medical facts, and then from his own personal experience to tell. But before that, I note that the vitamin B3 - is now more remedy than a vitamin. In the cosmetics used not niacin and niatsiamid. First, the molecule niacinamide easier and better penetrate the skin. And secondly, it is less "hard" than niacin: does not expand as much vessels to hives.
And now for the effects of:
1) less allocated sebum on the face: Was conducted study (Attended by Japanese and Caucasians), in which one half of the participants inflicted moisturizing cream with 2% niacinamide, the other - the usual moisturizer. After 4 weeks of the experiment, the Japanese, who used 2% niacinamide - generating speed sebum significantly decreased. But Caucasians differently everything: the results of a 6-week experiment found that those who used 2% niacinamide, fell markedly the level of sebum on the face. This is useful information for those who have oily skin type;
2) not only moisturizes and improves the skin's protective barrier, plus helps get rid of rosaceaWhich, incidentally, is visually very old one (here here study);
3) results in the order of flabby and dehydrated skin (all because that restores the skin's barrier function);
4) The most interesting - to help get rid of hyperpigmentation and lighten skin (study here);
5) a dull color tone lightens;
6) Vitamin B3 - an antioxidantAnd my regular readers have long known that they play a crucial role in the rejuvenation (even there is a theory of aging, which is based on free radicals, antioxidant - a fighter against free radicals);
7) has beneficial effects on the synthesis of collagen and elastin (more here).
My personal experiences with niacinamide: from skin after a couple of days becomes even color, smooth and visually it looked very well maintained. Since niacin I got a different picture: of a 2% solution hour face was burning, but then with the experience and after reading a bunch of sources knew that the concentration is high for me :-)
Niacinamide - it is more gentle. It is possible to make the most of the solution (buy powder niacinamide) and dilute with water or alcohol. Will work. But with niacin should be more careful, 1% for me kntsentratsiya - at the ceiling already.
The following article will tell in detail about the funds with niacinamide, which are stupid and which - workers. If it is interesting - put the "thumbs up" and subscribe to the channel.
