The whitening effect of Niacinamide is becoming more and more popular. But do you know the precautions for its use? Here SpringCHEM will tell you.
1. Tolerance test should be done when using Niacinamide products for the first time
It has a certain degree of irritation. If you use a large dose of it for the first time, it may cause facial irritation, which is not good for skin health. Therefore, it is best to use a small amount of it for the first time, and then increase the dose after tolerating it.
2. Use with caution for sensitive skin
It has the effect of exfoliating the cuticle of the skin. The sensitive skin itself is more sensitive and fragile, and the stratum corner is thinner. Therefore, sensitive skin should be careful to use skin care products containing Niacinamide ingredients, so as not to stimulate the skin and aggravate its sensitivity of the skin.
3. When used, it can not be mixed with acidic substances. This is because when these two substances are mixed, they will release a large amount of niacin, which will cause skin irritation. Whenever possible, use the same brand of skin care products. This is because the developers of products from the same line or brand will pay attention to what are the contraindications of Niacinamide use, so it can make users feel more comfortable using it. People with sensitive skin or skin with red blood cells should not use whitening products with it. Pregnant women should not use them either.
4. Although it has a whitening effect, in the process of use, you should also pay attention to sun protection. Exposure to the sun can cause great damage to the skin and can promote the production of pigmentation and melanin. In this case, the whitening effect of Niacinamide is minimal.
