Should niacinamide be used during the day or at night?

Niacinamide stock solution can be used during the day and at night. Generally speaking, niacinamide can be used once at night, but if you want to achieve a quick whitening effect, you can use niacinamide in the morning and evening to help whiten your skin, and just do a good job of sun protection during the day.

Does niacinamide stock solution need to be used away from light?

Normally this is not necessary. Niacinamide is a beauty ingredient, also known as nicotinamide, which is an amide compound of niacin. There is no need to avoid light when using niacinamide skin care products. However, after using niacinamide, be careful not to expose your skin to the sun to avoid sunburn. Moreover, no matter how good the whitening effect of niacinamide is, you will get tanned if you don't pay attention to regular care.

Can I turn on the light after using niacinamide stock solution?

Can. Niacinamide is not photosensitivity. You can turn on the light during or after applying niacinamide. Turning on the light will not affect the effect of niacinamide. If the light in the room is weak, you must turn on the light after applying niacinamide. This will make it easier to see and avoid uneven application.

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.
