Does the higher the niacinamide concentration, the better the whitening effect? ​​What is the standard niacinamide concentration?

Niacinamide is no stranger to those who often look at the ingredients of cosmetics and skin care products, especially whitening skin care products, most of which contain niacinamide. The difference is that the content of niacinamide is different. So, does the higher the niacinamide concentration, the better the whitening effect?

Does the higher the concentration of niacinamide, the better the whitening effect?

In theory, the higher the concentration of niacinamide, the better the whitening and anti-aging effects will be. However, this is not realistic. Tolerance must also be considered. The higher the concentration, the stronger the irritation. The skin will become abnormal and unbearable. Therefore, it is not recommended.

What is the standard concentration of niacinamide in cosmetics?

2%-5%. The niacinamide concentration is based on 2% and should not be higher than 5%.

The concentrations of niacinamide products on the market are all different, with the lowest being 2% and the highest being 10%. When the concentration is lower than 2%, the skin's absorption rate increases linearly. When the concentration is higher than 2%, the absorption rate will not be so fast. Although the whitening and anti-aging effects will become better and better with higher concentrations of niacinamide, tolerance must be considered. The higher the concentration, the stronger the irritation will be, and abnormalities will occur on the skin.

What is the appropriate concentration of niacinamide?

It is generally recommended to start with a 2% concentration and then increase the concentration when the skin tolerates it. However, the concentration of niacinamide should not be higher than 5%. Any content higher than this is a high concentration of niacinamide, and the skin will easily show obvious symptoms of intolerance.
