The Science Behind Niacinamide (Vitamin B3)

How Niacinamide (Vitamin B3)'s key actives work — and why formulation and delivery matter as much as the ingredient itself.

VITAMIN B3

What Niacinamide Is

Niacinamide is a form of vitamin B3 — a multitasking, well-tolerated active that supports the barrier, tone, oil balance and redness all at once.

BARRIER

Barrier & Hydration

It increases ceramide and fatty-acid production, helping skin hold moisture and become more resilient to irritation.

PAIRS WELL

Layers With Everything

Gentle and stable, niacinamide combines safely with vitamin C, retinol, exfoliating acids and peptides.

ALL SKIN TYPES

Suits Sensitive & Oily

Its low irritation risk makes it a rare active that works for sensitive, oily and acne-prone skin alike.

These descriptions reflect how each ingredient category works in general dermatological terms. Individual results vary, and skincare is not a substitute for professional medical advice.

Niacinamide (Vitamin B3): Frequently Asked Questions

What is niacinamide and what does it do?

Niacinamide (vitamin B3) is a multitasking skincare active that strengthens the moisture barrier, evens tone, calms redness and helps balance oil and pores. It's one of the few ingredients that suits virtually every skin type.

What is the best niacinamide serum in Canada?

A standout option is AlumierMD Ultimate Boost Serum, which pairs niacinamide with peptides and a growth factor. For acne-prone skin, Acne Balancing Serum is a great niacinamide-powered pick.

What does niacinamide do for your skin?

It supports the skin barrier, helps fade dark spots and uneven tone, reduces the look of redness and enlarged pores, and helps regulate oil — making skin look calmer, clearer and more even over time.

What is the best niacinamide product for oily or acne-prone skin?

For oily and breakout-prone skin, Acne Balancing Serum and the niacinamide-rich EltaMD UV Clear SPF 46 are excellent, since niacinamide helps control oil without stripping the skin.

Can I use niacinamide with vitamin C?

Yes. Despite an old myth that they cancel out, modern vitamin C and niacinamide formulas work well together and can be layered for added brightening and barrier support.

Can I use niacinamide with retinol?

Yes, and it's a great pairing. Niacinamide helps buffer the dryness and irritation that retinol can cause, making your retinol routine more comfortable.

What percentage of niacinamide is best?

Most effective formulas use around 4-5% niacinamide, which delivers benefits with very low irritation risk. Very high percentages aren't necessary and can occasionally cause flushing in sensitive skin.

Is niacinamide good for sensitive skin and rosacea?

Yes — niacinamide is calming and well tolerated, which makes it a favourite for sensitive and rosacea-prone skin looking to reduce redness and strengthen the barrier.

Does niacinamide help with pores and oil?

Yes. By helping regulate oil production, niacinamide can refine the look of enlarged pores and reduce shine. Explore more in our oil control collection.

How long does niacinamide take to work?

Barrier and hydration benefits can appear within a couple of weeks, while improvements in tone, redness and pores typically build over 8-12 weeks of consistent use.

Where can I buy authentic niacinamide skincare in Canada?

WeDoSkin is a Preferred Authorized Canadian Retailer for AlumierMD, EltaMD, SkinCeuticals and more, so every niacinamide product is authentic, fresh and shipped fast Canada-wide.
