Original title: ingredient peeling | is owning nicotinamide equal to mastering wealth code? Nicotinamide: in busy, do not disturb.
It is often said that \
In the general trend of whitening, \
But the higher the degree of discussion, the more people want to let it fall from the altar. So what is the existence of nicotinamide? Can it achieve virtue coordination? Today, epped will take you to peel off its vest layer by layer and explore the secrets hidden in nicotinamide~
Nicotinamide doesn’t sound like our common vitamin ABCDE, but it’s actually a member of a serious vitamin family. It’s just because it’s an amide compound of vitamin B3, and vitamin B3 has a nickname nicotinic acid, so it’s called nicotinamide. In addition, you can also call it vitamin PP, nicotinamide, nicotinamide Nicotinamide… Anyway, there are many names. Just listen to them.
However, as a member of vitamin B, nicotinamide naturally has to fulfill the responsibility of vitamin B.
At first, its daily task was to be responsible for clinical treatment of skin problems such as skin disease, stomatitis and glossitis caused by vitamin B deficiency, until it was selected by skin care products industry because of its whitening, anti-aging effect and relatively cheap price.
Appreciation of business ability
Starting concentration: 3% ~ 5%
Nicotinamide is best known for its whitening effect. Let’s sit down and talk about it.
The previous VC peel epped has talked about the process of melanin formation and the whitening mechanism of VC, but the situation of nicotinamide is different.
First of all, we know that tyrosinase stimulates tyrosine to produce DOPA and then form melanin, but the story of melanin is not over yet.
As the saying goes, people run high and water flows low. Melanin has ideals and goals. Naturally, they are unwilling to degenerate into frogs in the bottom of the well, so they will move towards the epidermis. However, the epidermis has its own working frequency, and it can’t entertain a huge army of melanin all the time. Therefore, the dilemma of melanin is blocked in the epidermis, so from the perspective of human beings, The skin becomes dark and speckled.
In order to solve this problem, nicotinamide appeared. Although it can’t restore the melanin that has been formed like VC, it can firmly hold the road leading to the epidermis and prevent the melanin from transferring to the epidermis. In this way, melanin can’t climb up, and the skin will not be affected naturally. It can still maintain its white and tender appearance~

Starting concentration: 2%
At present, there are few literatures about nicotinamide oil control, but in a few reports, we can still capture a key information: \
10% nicotinamide +1% zinc essence
10% high concentration nicotinamide can not only brighten the skin color, but also effectively clean the pores. Combined with 1% zinc, it can also adjust the water and oil balance of the skin, which is the gospel of oil pox!

Starting concentration: 5%
Before we talk about this, let’s popularize a few knowledge points. Nicotinamide is not only a derivative of vitamin B, but also a precursor of NAD (nicotinamide adenine dinucleotide), and its reducing form NADPH (reducing coenzyme II) is actually one of the culprits leading to skin aging.
Knowing these key factors, we will reorganize the following ideas: skin loss due to NADPH deficiency can reduce collagen content, while nicotinamide can be converted to NAD, and NAD can be reduced to NADPH, that is, nicotinamide can increase the content of NADPH in skin, and then help skin improve collagen production and play an anti aging effect.
However, nicotinamide is very resistant to aging, and the concentration needs to reach 5% to see the effect. If you want to use nicotinamide to resist aging, you must see clearly the concentration of HA.

· about intolerance·
When it comes to nicotinamide, some people always talk about \
Why do you say that? Because nicotinamide is a compound of nicotinic acid, it is inevitable that there will be some nicotinic acid residue in the process of treatment
Nicotinic acid has the function of dilating blood vessels. A little increase in the content of nicotinic acid may irritate the skin and cause skin redness (that is, the root cause of nicotinamide intolerance).
Therefore, in order to reduce irritation, businesses will try their best to improve the purity of nicotinamide. Olay has done a good job, otherwise its small white bottle series would not have been popular for so many years~
About long hair·
In addition to intolerance, \
As a matter of fact, there is no clear result about whether the use of nicotinamide will grow hair. However, combined with the description of consumers and the analysis of the efficacy of nicotinamide, many skin care industry leaders have also given their own conjectures. You can make a reference~
Nicotinamide has a whitening effect on the skin, so the hair hidden in the dark skin becomes obvious.
Nicotinamide can repair the skin barrier to a certain extent. It may be that after the use of nicotinamide, the skin barrier becomes more healthy, and the originally depressed hair follicles are rejuvenated, and the hair naturally grows out.
However, no matter what the situation is, eppend still adheres to the principle of fairness and justice to explain for nicotinamide. At present, the issue of hair growth has not been proved to be absolute. After all, if nicotinamide is proved to help hair growth, what’s the matter with baldness? And everyone’s skin texture is different, and the effect is not the same, So if you want to whiten, try it~
Does nicotinamide need to be protected from light?
Nicotinamide does not have photosensitivity and phototoxicity, when to use is no problem, bold use it~
Is nicotinamide edible?
I didn’t expect that, in fact, many foods contain nicotinamide. For example, our common meat, fish and nuts are happy hometown of nicotinamide. Eating more of these foods can prevent some skin problems, and the benefits are great!
The higher the concentration of nicotinamide, the better?
With the increase of nicotinamide concentration, the concentration of nicotinic acid will also increase, the stronger the irritation will naturally be, and the skin with high concentration of nicotinamide is also difficult to digest, which is really terrible!
