How to determine niacinamide intolerance

1. Tingling sensation

After using niacinamide, you may feel a slight tingling sensation on your face. If tingling occurs, you should reduce the amount and frequency of use of niacinamide.

2. Redness and fever

When niacinamide is above or below pH 6, it becomes unstable and will fuse with water to form niacin. Niacin can promote blood circulation in the human body, but too fast blood circulation is not a good thing, which can cause congestion, redness, and fever of facial capillaries. If you experience redness or fever after using niacinamide, stop using it immediately.

3. Very itchy

After using niacinamide, your face no longer itches. This is also a sign of intolerance. You should stop using it immediately and decide whether to continue using it after the itching subsides. When your skin itches, don't scratch it with your hands. If the skin is scratched, it will be easily affected by bacteria.

4. There is a rash

Rash is a typical sign of niacinamide intolerance. If rash appears, the amount of niacinamide used should be reduced.

Should I use low or high concentration of niacinamide first?

Low concentration.

The whitening effect of niacinamide is indeed very good. Many whitening products contain niacinamide. For people with yellow skin, it is simply a blessing. When you first start using niacinamide, you cannot use a high concentration. Start with 2% niacinamide. You need to build up a tolerance to niacinamide. Once you have tolerance, you can gradually increase the amount, concentration, and frequency of use. Don’t be too anxious at the beginning and don’t expect to whiten your skin after just one use. The Great Wall wasn’t built in a day.

That’s all I have to say about niacinamide. Now you know the symptoms of intolerance! Start with a low concentration, use a small amount, and don’t use it too frequently.
