【Skincare News Series】
Hello Hello, hello, I am Seven small 7, I don't know if you have that feeling, that is, since the "niacinamide" ingredient has been on fire, it has begun to promote and market various balabala, until 2020, when it is a complete burst of fire (18 years and 19 years are also hot Ha, but the stage of 2020 is the hottest) Some merchants began to smell business opportunities!!!
Since then, the "inner roll road" of niacinamide has begun!
The initial concentration of niacinamide 2% to 3% is now 8% to 10% concentration of niacinamide!
What really happened during this time???
How did the inner volume become so bad???
Then we have to say that these two inner volume big guys;
One is PG (bao*) and the other is TO(The Ordinary)
This is also the comparison of small 7 I often take as an example, the first was developed by PG side of the various effects of niacinamide and until now continuous optimization, last year began to have a new research breakthrough, found that niacinamide in the acidic environment has a "autophagy" effect.
Have to say;
Including niacinamide oil control, whitening, and improving skin roughness are basically studied on the PG side, and a number of related literature have been published today to have the status of niacinamide, but why is TO rolled up? The reason is that TO, as the representative of the "high concentration raw material barrel", has launched a niacinamide extract with a concentration of up to 10%.
As the development of niacinamide so many effects of PG is only capped at 5%.
There are many people who say that PG families dare not use high concentrations of nicotinamide barbarala, but today to come to a shocking explanation of your three views!
[Niacinamide is not the higher the concentration, the better the effect! 】
It turns out that niacinamide is more about "overall formulation coordination" than a single ingredient concentration.
This is basically the same as other ingredients, and sometimes the coordination of ingredient formulations is much better than the amount of addition of a single ingredient concentration!
And PG's O**Y small white bottle is a typical example;
It does not rely solely on the ingredient niacinamide to block melanin transmission, but compound undecylphenylalanine for multiple whitening pathways to achieve the effect of whitening, but in addition to these, in the formula also takes into account the irritation brought by the higher concentration of niacinamide, compounded with dipotassium glycyrrhizinate + panthenol for soothing work, the overall formula is basically no "conceptual" addition.
On the other hand, 10% niacinamide + 1% zinc on the TO side
It is also true that the irritation of high concentrations of niacinamide is added to 1% zinc for neutralization, but its irritation is far from enough to eliminate.
There are statistics:
The niacin content in TO niacinamide essence is 172ppm, while the O**Y small white bottle is 11ppm, the gap between the front and back is too large, and the irritation is relatively large.
Therefore, some sensitive skin types or dry skin types are not suitable for using TO's 10% high concentration essence.
moreover!
Due to the reason of the formula, the small white bottle has more than one whitening pathway, although there is only 5% concentration of niacinamide, but the whitening effect is better than the 10% concentration of TO, and the irritation of 5% is definitely far below 10%, so the concentration of niacinamide is not the higher the better!
All right.
That's what this newsletter is about!
I hope that the inner volume in the skincare circle can be less, and QAQ can't stand it!
