Niacinamide is one of the most versatile ingredients in Korean skincare. It can help support the skin barrier, improve uneven skin tone, refine skin texture, and, at certain concentrations, reduce sebum production.
But what exactly does niacinamide do, how should you use it, and is it really suitable for every skin type? Let’s take a look at why niacinamide has become one of modern skincare’s favorite active ingredients!
What Is Niacinamide?
Niacinamide, also known as nicotinamide, is a form of vitamin B3. This water-soluble vitamin has long been studied in skincare and is found in many cosmetic formulas, from moisturizers and serums to creams.
What makes it especially interesting is that it doesn’t focus on just one concern.
It can be an appealing choice for people who:
- are dealing with uneven skin tone,
- want to reduce the appearance of dark spots,
- have oily or combination skin,
- want to support their skin barrier,
- want to brighten dull, tired-looking skin,
- or are simply looking for a versatile active ingredient that pairs well with others.
That’s why niacinamide is not just a trendy ingredient, but an active skincare ingredient that has been researched for a long time.
What Does Niacinamide Do for Skin?
One of niacinamide’s greatest benefits is that it can be a useful part of a well-designed routine for a range of skin concerns.
1. Supports the skin barrier
Among other things, the skin barrier helps retain moisture and protect the skin from external environmental factors.
Niacinamide may help support the skin’s barrier function, making it particularly interesting for dry, dehydrated, or easily irritated skin. However, this doesn’t mean that niacinamide alone “restores” the skin barrier. Proper hydration, gentle cleansing, and avoiding over-exfoliation are just as important.
To learn more about the skin barrier and how to care for it, read our guide to restoring the skin barrier.
2. May help with uneven skin tone and dark spots
One of niacinamide’s well-known cosmetic benefits is that it helps promote a more even skin tone. Research suggests that niacinamide may affect the transfer of melanosomes from melanocytes to keratinocytes, which may play a role in skin pigmentation. In a clinical study, using a moisturizer containing 5% niacinamide reduced hyperpigmentation after four weeks compared with the control. That’s why niacinamide can be a good addition to a routine designed for dark spots and dull skin tone.
Important, though: sun protection is essential when dealing with dark spots. Don’t expect any serum to solve pigmentation on its own.

3. May also be useful for oily skin
If your skin often looks shiny, niacinamide may also be an interesting ingredient. In a clinical study, topical use of 2% niacinamide lowered measurements used to assess sebum production in certain study groups. However, this doesn’t mean that niacinamide “dries out” or completely mattifies the skin.
In fact, oily skin needs hydration, too. The goal is to create a balanced routine, not to strip the skin of oil at all costs.
4. May help care for mature skin
Niacinamide has also been studied in relation to the appearance of aging skin. In a 12-week clinical study, participants using a formula containing 5% niacinamide showed improvements in the appearance of fine lines, dark spots, skin texture, and redness, among other things. This makes niacinamide a particularly good fit for an anti-aging routine, too. And this is where another popular active comes in: retinal.
Niacinamide and retinal – do they work well together?
Yes.
Niacinamide and retinal support skincare goals in different ways, so they can complement each other well. Retinal is a vitamin A derivative, primarily chosen to address signs of skin aging, fine lines, and skin texture.
Niacinamide, on the other hand, is more versatile: it may be useful for supporting the skin barrier and addressing uneven skin tone and skincare concerns related to sebum. So you don’t necessarily have to choose between them. In a well-formulated routine, they can even appear in the same product.
For example, NIDA Youthful Formula™ Yam Mucin ABCE Boosting Serum contains both niacinamide and retinal, as well as wild yam root extract, panthenol, vitamin E, and a vitamin C derivative, among other ingredients. The brand positions the product to help address uneven skin tone, drier/rougher texture, dull skin, and the appearance of fine lines.
Niacinamide and vitamin C – can you use them together?
Yes.
Older skincare advice often said that niacinamide and vitamin C shouldn't be used in the same routine. However, with today's cosmetic formulas, you don't necessarily need to avoid this combination. Niacinamide and vitamin C can be incorporated into your routine in different ways, and many modern product formulas combine several active ingredients. If you have sensitive skin, it's naturally worth introducing new products gradually and paying attention to how your skin responds.
The NIDA ABCE product line is based on this very concept: vitamins A, B, C, and E are combined in one formula.
What percentage of niacinamide is ideal?
This is one of the most common questions.
A higher concentration doesn't automatically mean better results. With niacinamide, the overall formula, your skin's condition, and whether you use it regularly and consistently are at least as important as the right concentration. If you're just starting to use niacinamide, you don't necessarily need a very high-concentration serum. A well-formulated product with a lower or medium concentration can also be a good starting point. What's more, if your routine already includes several active ingredients - such as retinal, acids, or vitamin C - it's especially worth avoiding the "more is better" approach. Your skin doesn't need as much as possible of one ingredient; it needs a well-balanced routine.
How do you use niacinamide?
One benefit is that it's generally easy to incorporate into your daily routine.
A simple routine could look like this:
Morning:
- Gentle facial cleanser
- Toner or essence
- Serum containing niacinamide
- Moisturizer
- Sunscreen
Evening:
- Facial cleanser
- Toner or essence
- Niacinamide serum
- Moisturizer
If you use retinal, it's generally best to include it in your evening routine.
Niacinamide can also be used in the same routine, if your skin tolerates it well.

Niacinamide for oily skin - could it be a good choice?
Niacinamide may be especially beneficial for people with oily or combination skin. One reason is that its effect on sebum production has been studied at certain concentrations.
But there's another important point. Oily skin can also be dehydrated.
If you try to get rid of your skin's shine with harsh cleansers, products containing alcohol, or over-exfoliation, your routine can easily become too harsh.
Niacinamide for dry skin - can you use it?
Of course.
Niacinamide isn't just for oily skin. Because it's also associated with supporting the skin barrier, it can be a useful part of a hydrating routine for dry or dehydrated skin, too. However, if you have dry skin, it's worth combining niacinamide with hydrating ingredients.
For example:
- hyaluronic acid,
- glycerin,
- panthenol,
- squalane,
- ceramides.
This way, you're not basing your routine on a single active ingredient, but addressing hydration and skin comfort at the same time.
NIDA and niacinamide - which product contains it?
One of the key ingredients in the NIDA Youthful Formula™ Yam Mucin ABCE Boosting Serum is niacinamide, combined with retinal, wild yam root extract, panthenol, and vitamin C and vitamin E derivatives. The serum is made in Korea and comes in a 50 ml size.
The NIDA Youthful Formula™ Yam Mucin ABCE Facial Cream also contains niacinamide, retinal, panthenol, vitamin C and vitamin E derivatives, as well as wild yam root extract. The brand positions the cream as a moisturizing product that supports the skin barrier and improves texture.
These two products may be particularly interesting if you want to target hydration, uneven skin tone, and anti-aging skincare in your routine.
Can niacinamide be used every day?
Niacinamide is generally a well-tolerated cosmetic ingredient and, according to the literature, is widely used in various skincare formulations. However, that doesn’t mean every skin type reacts the same way. If your skin is sensitive, it’s always best to introduce new products gradually. And if you start using several new active ingredients at once, it will be hard to tell which product caused any irritation.
Less is sometimes more - especially when you’re just starting to build your routine.
Niacinamide and acids - can you use them together?
Niacinamide can be combined with chemical exfoliants, such as AHAs and BHAs, in a well-planned routine. Still, it’s worth being cautious if your skin is sensitive.
For example, if you start using these all at once:
- niacinamide,
- BHAs,
- AHAs,
- retinal,
- vitamin C
and even more active ingredients, it can easily be too much for your skin.
In these cases, the problem isn’t necessarily that the ingredients “don’t work well together,” but that you’re using too many active products at once.
Build your routine gradually and give your skin time to adjust.
5 common mistakes when using niacinamide
1. Assuming a higher percentage is automatically better: Concentration alone doesn’t tell you everything about a product.
2. Using too many active ingredients at once: You don’t need to add every other trendy ingredient alongside niacinamide.
3. Neglecting hydration: Proper hydration is important even for oily skin.
4. Not using sunscreen: Consistent sun protection is especially important for dark spots and uneven skin tone.
5. Expecting results too quickly: Skincare is a long-term process. A consistent routine matters much more than expecting visible changes after just a few days.
Who can benefit from niacinamide?
Thanks to its versatility, niacinamide can be part of many skincare routines.
It may be especially worth considering if:
- Your skin is oily or combination: It may be useful for skincare goals related to sebum.
- Your skin is dry or dehydrated: It may be a good addition to support the skin barrier.
- Your skin tone is uneven: It can be part of a routine aimed at reducing the appearance of pigmentation.
- Your skin looks dull: Together with other active ingredients, it can help promote a more even, radiant-looking complexion.
- Your skin is mature: It also pairs well with retinals, peptides, and hydrating ingredients in an anti-aging routine.
