What is the appropriate concentration of niacinamide? Is the higher the concentration of niacinamide, the better?

Speaking of niacinamide, its most significant effect is whitening. It can be described as a whitening magic tool. It is loved by many female friends. Let’s take a look at what is the appropriate dosage of niacinamide? Is the higher the concentration, the better?

What is the appropriate concentration of niacinamide?

Start with a 2% concentration. 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 develop symptoms of intolerance.

Niacinamide is a type of vitamin B3 that can quickly pass through the stratum corneum of the skin and reach the deep layer of the skin, blocking the circulation of melanin. The melanin at the bottom of the skin is reduced, and the skin becomes whiter. However, niacinamide contains niacin, which is somewhat irritating to the skin. When you first use it, use a low concentration and a small amount to allow the skin to establish a tolerance to niacinamide. If the skin is intolerant to niacinamide, it will cause allergies, redness, itching and other symptoms.

Is the higher the concentration of niacinamide, the better?

The higher the concentration of niacinamide, the better.

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.

That’s all I have to say about niacinamide. Start with a 2% concentration and increase the concentration once your skin tolerates it.
