How to choose the concentration of niacinamide? Let's first look at the difference in niacinamide concentration
2% concentration of niacinamide has the effect of controlling oil and repairing the skin barrier.
If you want to play a role in whitening, it is better not less than 3%.
Eggz, a senior executive of product development of the OLAY brand, pointed out that through their continuous verification, the content of niacinamide in skin care products is more appropriate at about 5%. The amount of 5% added is enough to make the product play a very good whitening effect, and it can better control the hidden dangers of product stimulation. Most importantly, if the content of niacinamide is higher than 5%, the whitening effect of the product cannot be significantly increased. Therefore, the concentration of niacinamide in OLAYA products is usually about 5%.
Why does TheOrdinary need to add niacinamide with such a high concentration value? This is mainly because Europe and the United States have different concepts in formula design. Directly said that European and American people have thick skin, strong tolerance, and can bear it.
The following are different concentrations of niacinamide products, we buy it according to it, it is recommended to collect!
But overall, the content of niacinamide is indeed not the higher the better! Adding a little more niacinamide also adds a little more probability of skin allergies, which poses a certain threat to the safety of the product. The content is within 10%, basically the utilization efficiency of niacinamide can achieve the best effect.
Niacinamide costs
Niacinamide is really not too expensive! So many well-known brands love to use niacinamide, one of the most important factors is that it is really cheap!
Lonza, the world's largest manufacturer of niacinamide, has less than 1 kilogram of niacinamide (cosmetic grade) of less than 100 yuan, which translates to less than 1 dime per gram. In other words, the cost of nicotinamide in a simple bottle of skin care products may not be higher than fifty cents, compared to other whitening raw materials of thousands of yuan a kilogram at every turn, the price of niacinamide is indeed very close to the people.
The difference between a high-priced product and an affordable product
On why some of the products that promote the niacinamide ingredient are priced so high
1. Most of the skin sensation with a higher price is also a little better, and the purity of niacinamide (the definition of differential concentration) will also be higher, and the stimulation effect of high purity of niacinamide will be relatively low.
2. In addition to niacinamide, the product may also add other ingredients, for example, SKII's small bulbs will also add their core ingredient PITERA. Regarding the actual effect, the whitening effect is much the same, and the small bulb has a little more anti-inflammatory effect.
3. Marketing, advertising, packaging also costs a lot of money.
If it is to better pursue whitening skin, you can actually buy all the price points.
In addition to whitening the skin, there are requirements for skin feeling, and the medium level price can be, because the final whitening effect is the same.
There is no shortage of money for you at will
At the end, we still need to warmly remind you: niacinamide has a certain irritation, beginners must not rush to achieve, it is best to start from a low concentration gradually to establish tolerance.
