Precautions for using niacinamide

1. When using niacinamide products for the first time, you should do a tolerance test: Niacinamide is somewhat irritating. If you use a large dose of niacinamide for the first time, it can easily cause facial irritation, which is not good for skin health. Therefore, it is best to use a small amount of niacinamide for the first time, and then increase the dose after tolerance.

2. Use with caution on sensitive skin: Niacinamide has the effect of exfoliating dead skin cells. Sensitive skin is more sensitive and fragile, and the stratum corneum is relatively thin. Therefore, people with sensitive skin should use skin care products containing niacinamide with caution to avoid irritating the skin and increasing skin sensitivity.
