Niacinamide: Benefits, Uses, Side Effects & How to Use It
Niacinamide is one of the most widely used ingredients in modern skincare. It is a form of vitamin B3 that appears in products designed for oily skin, uneven skin tone, visible pores, redness, dehydration and general skin-barrier support.
But niacinamide is not a miracle ingredient, and no serum can realistically fix every skin problem overnight.
Used consistently and appropriately, niacinamide can be a useful part of a balanced skincare routine.
What is niacinamide?
Niacinamide, also called nicotinamide, is a water-soluble form of vitamin B3.
In skincare, it is used in a variety of concentrations and product types, including serums, moisturizers and cleansers.
Its appeal comes from its versatility. Rather than targeting only one concern, niacinamide can support several aspects of skin health.
What does niacinamide do for skin?
Niacinamide is commonly used to support:
- The skin barrier
- Moisture retention
- The appearance of uneven skin tone
- The appearance of excess oil
- Overall skin texture
- The appearance of redness associated with irritation
The important distinction is that these are gradual skincare benefits, not instant transformations.
Niacinamide and the skin barrier
Your skin barrier helps reduce water loss and protects the skin from external irritants.
Niacinamide is commonly included in formulations intended to support barrier function and moisture retention.
This makes it useful for people who want a treatment ingredient without building an unnecessarily aggressive routine.
Is niacinamide good for oily skin?
Niacinamide is frequently used in skincare for oily and combination skin.
If excess oil is one of your main concerns, a niacinamide serum can be incorporated after cleansing and before moisturizer.
However, niacinamide should not be treated as a replacement for acne medication when you have clinically significant acne.
Niacinamide and enlarged pores
Niacinamide cannot permanently “close” or eliminate pores.
Pore size is influenced by genetics, skin structure, age and sebum production.
What niacinamide may do is improve the appearance of skin by supporting oil control and overall skin condition, which can make pores appear less noticeable.
That is a much more accurate promise than pretending a serum has physically deleted your pores from existence.
Niacinamide for dark spots and uneven skin tone
Niacinamide is commonly used in routines targeting uneven pigmentation and post-breakout marks.
For darker skin tones, post-inflammatory hyperpigmentation can be particularly noticeable after acne or inflammation. Dermatologists recommend addressing the underlying acne or inflammation while also protecting the skin from further UV exposure. (American Academy of Dermatology)
Niacinamide can be one component of such a routine.
It should not be presented as a guaranteed treatment for melasma or other diagnosed pigmentation disorders.
Niacinamide for acne
Niacinamide may be useful as part of a skincare routine for acne-prone skin, particularly when oiliness, redness or post-acne marks are concerns.
However, acne is a medical condition and different types of acne require different treatments.
For persistent, painful or scarring acne, consult a dermatologist.
The American Academy of Dermatology recommends gentle skincare and warns that overly irritating products can make acne appear worse. (American Academy of Dermatology)

Can niacinamide be used every day?
Many people use niacinamide daily, but frequency should depend on the formulation and your skin’s tolerance.
If you are new to a product, start conservatively.
If you experience persistent burning, redness, itching or irritation, stop using it and reassess your routine.
Can niacinamide be used with vitamin C?
Modern skincare formulations can contain or layer niacinamide and vitamin C.
The old blanket warning that these ingredients can never be used together is overly simplistic.
What matters more is whether the individual products are appropriate for your skin and whether the combination causes irritation.
Can niacinamide be used with hyaluronic acid?
Yes. Niacinamide and hyaluronic acid are commonly used together.
A simple order is:
Cleanser → hydrating serum → niacinamide → moisturizer
However, follow the instructions of the individual products.
Can niacinamide be used with glycolic acid?
It can be possible to use both ingredients in the same overall routine, but that does not mean you need to layer every active ingredient simultaneously.
If your skin is sensitive, use glycolic acid less frequently and keep the rest of your routine simple.
Orior currently sells both Niacinamide 10% Jelly and glycolic-acid-containing products. (Orior Cosmetics)
Niacinamide side effects
Niacinamide is generally well tolerated in skincare, but irritation can still occur.
Possible reactions include:
- Redness
- Burning
- Itching
- Dryness
- Small bumps or irritation
A reaction may also come from another ingredient in the formulation.
Patch testing a new product is sensible, particularly if your skin is sensitive.
Who should use niacinamide?
Niacinamide can be considered by people with:
- Oily skin
- Combination skin
- Normal skin
- Uneven-looking skin tone
- Visible pores
- Dehydrated skin
- Acne-prone skin
But no ingredient is universally appropriate for every person.
What percentage of niacinamide is best?
More is not necessarily better.
Skincare products are available at different concentrations, and a lower concentration may be sufficient for some people.
Orior’s product is formulated with 10% niacinamide, but the correct concentration for an individual depends on their skin, the rest of their routine and their tolerance. (Orior Cosmetics)
Frequently Asked Questions
Does niacinamide whiten skin?
Niacinamide should not be described as a skin-whitening treatment. It is better understood as an ingredient that can help improve the appearance of uneven skin tone and pigmentation.
Does niacinamide remove acne?
Niacinamide can support an acne-prone skincare routine, but it is not a universal acne treatment. Persistent or severe acne should be assessed by a dermatologist.
Does niacinamide reduce pores permanently?
No. Pores cannot be permanently eliminated by a serum. Niacinamide may help improve the appearance of pores by supporting skin condition and oil balance.
Can I use niacinamide twice a day?
Some people can tolerate daily or twice-daily use, but follow the product instructions and reduce frequency if irritation develops.
Can teenagers use niacinamide?
Niacinamide appears in many skincare products, but teenagers with persistent acne should focus on a simple, appropriate routine and seek professional advice when needed rather than accumulating a chemical laboratory on the bathroom shelf.
How long does niacinamide take to work?
Results vary by concern, formulation and individual skin. Avoid promises of overnight transformation. Consistent use over several weeks is a more realistic expectation for many skincare changes.
