Niacinamide is an amide compound of niacin. It is a white crystalline powder; odorless or almost odorless, bitter in taste; slightly hygroscopic. Soluble in water or ethanol, soluble in glycerol. Niacinamide was discovered early and was originally used to prevent inflammation of the mouth. Later, in 1974, a man named Girish Prasad Mathur discovered that niacinamide can absorb ultraviolet rays to prevent tanning and sunburn, and has a whitening effect when studying sunscreen, and therefore applied for two patents in 1974 and 1976. Niacin can be converted to nicotinamide in vivo, and although both compounds have vitamin effects, niacinamide is less pharmacologically and toxic than niacin, and these effects occur during the conversion of niacin. So niacinamide won't reduce cholesterol or cause flushing like niacin.
1. Whitening
Niacinamide can speed up metabolism and accelerate the exfoliation of keratinocytes containing melanocytes. The molecular weight of nicotinamide is small, which can be directly absorbed by epidermal cells, stimulate the vitality of some cells that have declined, promote the synthesis of collagen, prevent excessive melanin deposition, and achieve the effect of whitening.
It also has the effect of anti-glycation, which can dilute the yellow color of protein after glycation.
2. Anti-aging
Niacinamide can promote the synthesis of epidermal protein, enhance the skin's own defense ability, increase the skin's moisture content, and reduce the wrinkles, dark yellow and pigmentation of the facial skin. Niacinamide is widely used in anti-aging products.
3. Oil control and shrink pores
When the content of nicotinamide in the product reaches 2%, the production of fatty acids and triglycerides in the sebum secreted by the skin can be reduced, and the effect of controlling the secretion of oil can be achieved. To shrink, to achieve the purpose of reducing pores.
4. Acne
Studies have shown that a gel containing 4% niacinamide is effective in treating acne.
5. Prevention and treatment of pellagra, stomatitis, glossitis and other diseases.
1. Mainly used in skin care products, with multiple cosmetic effects.
2. Application in the field of medical science
3. It is a nutritional additive in food.
4. Can be used as feed additive.

Niacinamide is widely used in cosmetics, including not only skin care products such as facial cleansers, creams, lotions, and lotions, but also hair care products such as shampoos and conditioners. Usually mixed with rosin oil, glycerin, etc. and added to cosmetics;
Specification | Recommended Dosage |
Niacinamide 99% | 0.5%-2% |
When the concentration of niacinamide exceeds 5%, it is not easily absorbed by the skin; when it is less than 5%, the skin care effect will be moderated. Therefore, this product should be added appropriately within the dose range.
The pH of niacinamide should be controlled at 5-7. If the pH is lower than 5, it will decompose into niacin, which is irritating to the skin.
Avoid using in combination with acids such as salicylic acid and fruit acid, because under acidic conditions, niacinamide will decompose into niacin, causing irritation.
