Nicotinamide vs Niacinamide: Are They the Same Thing?
Nicotinamide vs Niacinamide: What's the Difference?
The short answer to nicotinamide vs niacinamide is that they are two names for exactly the same molecule. There is no difference in the ingredient, what it does or how well it works. The names simply come from different fields: "nicotinamide" is used more in science, medicine and supplements, while "niacinamide" is the name you see on skincare labels.
If that settles it for you, the rest of this guide explains why there are two names, what the molecule actually does and how it is used in skincare.
Nicotinamide vs Niacinamide: One Molecule, Two Names
Both nicotinamide and niacinamide are the amide form of vitamin B3. Chemically they are identical: the same pyridine ring with the same amide group (-CONH2) at the same position. There is no structural difference to separate them, which is why the two words are interchangeable.
It helps to place them next to their relative, niacin:
| Name | What It Is | Where You Usually See It |
|---|---|---|
| Niacinamide | The amide form of vitamin B3 | Skincare and cosmetic labels |
| Nicotinamide | The same molecule as niacinamide | Scientific, clinical and supplement contexts |
| Niacin (nicotinic acid) | A different form of vitamin B3, with an acid group instead of an amide | Supplements for cholesterol |
So in the nicotinamide vs niacinamide question, the two are the same, while niacin is a related but distinct molecule. The one-group difference between niacin and niacinamide is what makes niacin cause the familiar warm "flush," which niacinamide does not.
Why Does One Molecule Have Two Names?
The two names grew up in different places. Dermatology, pharmacology and nutrition science leaned toward "nicotinamide," and that is the term you will still find in research papers and on many supplement bottles. The cosmetics industry adopted "niacinamide," and it became the standard ingredient name on skincare products.
On an ingredient list, you will almost always see "niacinamide." If a product or paper says "nicotinamide" instead, it is the same active doing the same job.
What Niacinamide Does for Skin
Niacinamide is one of the most popular and well-studied actives in skincare because it is versatile and well tolerated. It is commonly used to:
- Support the skin barrier and help it retain moisture.
- Help even the look of skin tone and reduce the appearance of dark spots.
- Minimize the look of enlarged pores.
- Soften the appearance of fine lines.
- Calm the look of redness, which makes it a favorite for sensitive and acne-prone skin.
It also tends to play well with other actives, which is why it appears in so many serums and moisturizers.
Keeping Niacinamide Fresh: The Freeze-Dried Bead Option
Niacinamide is relatively stable compared with an active like vitamin C, but any water-based serum is still a multi-use product that needs preservatives and is exposed to air every time it is opened. One way around that is to keep the active dry until the moment of use.
That is the idea behind a freeze-dried bead. EVIK™ LyoPearl Niacinamide (Vitamin B3) is a single-dose bead that is lyophilized and sealed dry, then dissolved in water or serum when you apply it, so each dose is fresh and preservative-free. It is part of the wider freeze-dried single-dose skincare format, which also includes a vitamin C bead for anyone weighing up lyobead technology in vitamin C skincare.

Frequently Asked Questions
Is nicotinamide the same as niacinamide?
Yes. They are two names for the identical molecule, the amide form of vitamin B3. There is no difference in the ingredient or its effects.
Which name is "correct"?
Both are correct. "Niacinamide" is standard on skincare labels, while "nicotinamide" is more common in science, medicine and supplements.
Is niacinamide the same as niacin?
No. Niacin (nicotinic acid) is a different form of vitamin B3. It has an acid group where niacinamide has an amide group, and it can cause skin flushing that niacinamide does not.
Does it matter which name is on my skincare?
No. If a product lists either niacinamide or nicotinamide, you are getting the same active.
Is vitamin B3 the same as niacinamide?
Niacinamide is one form of vitamin B3. Niacin is another. Both belong to the vitamin B3 family, but they are not the same molecule.
Nicotinamide vs Niacinamide: The Bottom Line
Nicotinamide and niacinamide are the same vitamin B3 ingredient under two names, one favored by science and one by skincare. What matters far more than the label is the quality of the formula and how well it keeps the active fresh.
