Niacinamide in Korean Cosmetics: The Ingredient That Does It All
If you had to choose just one active ingredient for your skincare routine, the answer would be niacinamide. Also known as vitamin B3 or nicotinamide, it is the most versatile ingredient in modern cosmetics, and Korean cosmetics have been incorporating it into all kinds of products for years.
What is niacinamide?
Niacinamide is a form of vitamin B3 that is applied topically. It is water-soluble, stable (does not oxidize with light or air), compatible with practically all other active ingredients, and suitable for all skin types. It is basically the perfect ingredient.
Benefits of niacinamide
Reduces visible pores
Niacinamide regulates sebum production and improves the elasticity of the skin around the pore, making it visibly smaller. It is one of the few ingredients that can truly improve the appearance of pores without surgery.
Controls excess oil
Studies show that 2-5% niacinamide significantly reduces sebum production. Your skin is left matte without feeling tight.
Reduces blemishes and hyperpigmentation
Niacinamide inhibits the transfer of melanosomes (the "packages" of pigment) to surface cells. Result: blemishes gradually lighten without irritating the skin.
Strengthens the skin barrier
It stimulates the production of ceramides, the lipids that keep the skin barrier healthy and protected. A strong barrier = less reactive skin.
Gentle anti-aging effect
Stimulates collagen production and improves overall skin texture, reducing fine lines.

Frequently asked questions
Does niacinamide irritate the skin?
It is one of the least irritating active ingredients available. Only concentrations above 10% can cause temporary redness in very sensitive skin. K-Beauty products typically use 2-5%, which is the optimal concentration.
Can I mix niacinamide with vitamin C?
Yes. The myth that they are incompatible comes from a 1960s study with extreme conditions that do not occur in real cosmetics. You can use them together without problems.
What is the difference between niacinamide and niacinate?
They are the same in the context of cosmetics. Both terms refer to vitamin B3 in its topical form. If you see "nicotinamide" in the INCI, it is niacinamide.
