Nicotinamide, nicotinic acid, antipellagra vitamin – all these names refer to the same active ingredient, best known in cosmetics as niacinamide, a form of vitamin B3. It first gained attention back in 1937 when U.S. biochemist Conrad Arnold Elvehjem discovered that a lack of niacinamide in the body could lead to pellagra, a disease whose symptoms include dermatitis and even dementia.

Years of research followed, gradually revealing how niacinamide contributes to vital processes in the body – from cellular respiration and DNA repair to regulating stress resistance.

How Niacinamide Works in the Body

Our body produces niacinamide in several steps from tryptophan, an essential amino acid found in many foods. Animal products such as fish, meat, and organ meats are particularly rich in tryptophan, but it’s also present in plant-based foods like corn, wheat, nuts, and fruits.

Now you might wonder: how does niacinamide end up in creams and serums – and what does it actually do for our skin?

Niacinamide in Skincare

Let’s start with that last question. Today, countless studies confirm the benefits of niacinamide for the skin. That’s why it has become one of the most popular ingredients in modern skincare. According to research, it’s a true multitasker that can support and protect the skin in many ways when used regularly. Here are some well-documented examples:

• Brightens skin tone: Niacinamide can reduce hyperpigmentation and promote a more even complexion, giving the skin a natural glow.
• Refines pores: It helps minimize the appearance of pores, making the skin look smoother.
• Supports collagen and elastin production: This helps reduce fine lines and makes the skin appear firmer.
• Strengthens the skin barrier: A healthy barrier reduces moisture loss, combats dryness and fine lines, and protects against environmental stressors.
  
• Regulates oil production: Ideal for oily skin, as it can provide a mattifying effect.
• Soothes the skin: Niacinamide calms irritation, making it suitable for blemish-prone skin and reducing redness.
• Provides antioxidant protection: It neutralizes free radicals, helping to prevent cell damage.  (Read my blog post “Why Antioxidants Are Amazing” to learn more about these powerful defenders.)

How Niacinamide Is Made

Another reason niacinamide is so interesting for cosmetics is its production process. The niacinamide used in skincare is synthesized in the lab to be nature-identical. This approach conserves natural resources because no plants need to be grown or harvested. At the same time, synthetic production ensures high quality and purity. In its raw form, niacinamide is a white crystalline powder that is incorporated into skincare formulas at varying concentrations.

We use niacinamide, for example, in our  Active Concentrate Brightening Complex, designed to promote an even, radiant complexion. One last tip: the brightening effect of ingredients like niacinamide depends on consistent use. For best results, apply regularly for about 8 to 12 weeks.
