Can niacinamide be taken orally?

Niacinamide can be taken orally.

When taking niacinamide tablets, the recommended daily dietary intake is: 5-9 mg for newborn to 3 years old; 12 mg for 4-6 years old; 13 mg for 7-10 years old; 15-20 mg for male adolescents and adults; 13-15 mg for female adolescents and adults; 17 mg for pregnant women; and 20 mg for nursing mothers. During the course of taking the medicine, some people may experience dizziness, nausea, upper abdominal discomfort, loss of appetite, etc., but these symptoms will disappear on their own.

Can niacinamide be used long term?

Yes, but it is generally not recommended to use it every day due to niacinamide intolerance, but it depends on personal circumstances and the product. Many well-known products contain niacinamide, such as SK2 mini light bulb. You can use them under the guidance of professionals according to your skin condition.

When the concentration of niacinamide is below 2%, the absorption rate increases linearly with the amount added. When the concentration exceeds 2%, the absorption rate will no longer increase linearly. Although the higher the added concentration of niacinamide, the better the effect, the irritation will also increase greatly, and many people's skin simply can't stand it.

When we usually choose niacinamide products, we must start with low concentrations, and then gradually choose high-concentration niacinamide products after building skin tolerance. Another trick to reduce the irritation of niacinamide is to apply a thin layer of primer before using high-concentration niacinamide, and then apply niacinamide products. This can first moisturize the skin, adjust the skin to the best condition, reduce the speed of niacinamide penetrating into the skin, reduce irritation, and also achieve the purpose of whitening.

Okay, my friends, you know that niacinamide can be taken orally.
