Oily skin gets harder to manage the moment Canadian summer humidity sets in: excess shine, clogged pores, makeup that doesn't last past noon. Niacinamide has become the go-to active here because it regulates sebum while still hydrating, without the heaviness of richer formulas. Below, the niacinamide serums worth adding to your routine this summer, and why each made the list.
Our Top Picks at a Glance
- Best for Maximum Oil Control: SKIN1004 Niacinamide 10 Boosting Shot Ampoule
- Best Overall: Dr. Althea Vitamin C Boosting Serum
- Best for Sensitive or Barrier-Compromised Skin: Anua Rice Ceramide 7 Hydrating Barrier Serum
What Is Niacinamide, Exactly?
Niacinamide (vitamin B3) is a multitasking active that regulates oil production, strengthens the skin barrier, minimizes the look of enlarged pores, and helps fade post-acne marks. Unlike harsher oil-control ingredients, it works gradually and is well tolerated by most skin types, including sensitive and acne-prone skin.
Why It's Worth Adding
- Helps regulate excess sebum and reduce visible shine
- Minimizes the look of enlarged pores over time
- Strengthens the skin barrier, reducing breakout frequency
- Brightens uneven tone and fades post-acne marks
- Hydrates without adding heaviness, well suited to humid weather
What to Look For
- Skin type: Oily and combination skin benefit most, though niacinamide is gentle enough for most skin types.
- Ingredients: Look for niacinamide paired with tranexamic acid, ceramides, or vitamin C derivatives depending on your secondary concern.
- Texture: Watery, gel-based serums work best for oily skin in summer; avoid heavier oil-based formulas.
- Budget: Expect $16–$28 for a 30 to 50ml bottle.
The Best Niacinamide Serums for Oily Skin in Canada
Best for Maximum Oil Control: SKIN1004 Niacinamide 10 Boosting Shot Ampoule
Why we love it: This is the strongest option on the list, and one of the most talked-about new ampoules in K-beauty right now. 10% niacinamide paired with ascorbyl glucoside and centella asiatica delivers serious oil control and brightening in one step. We'd point genuinely oily skin here first, especially if a lower concentration hasn't been cutting it.
Key ingredients: 10% niacinamide, ascorbyl glucoside, centella asiatica
Benefits: Provides high-strength oil control and brightening in one of the most discussed new ampoules in K-beauty
Suitable for: Oily and combination skin seeking a stronger niacinamide concentration

Best for Sensitive or Barrier-Compromised Skin: Anua Rice Ceramide 7 Hydrating Barrier Serum
Why we love it: Oily skin that's also barrier-stressed from over-cleansing or one too many actives needs something gentler, and this is it. Seven rice extracts and ceramide NP pair with a lower 3% niacinamide concentration, balancing oil while reinforcing the barrier rather than fighting it.
Key ingredients: Seven rice extracts, ceramide NP, 3% niacinamide
Benefits: Balances oil while reinforcing the barrier, useful for breakout-prone summer skin
Suitable for: Oily skin prone to barrier damage from over-cleansing or active ingredients
How to Actually Use These
Apply after cleansing and toning, while skin is still damp. Use two to three drops, patted in gently rather than rubbed. Follow with a lightweight moisturizer, and SPF in the morning.
Mistakes Worth Skipping
- Skipping moisturizer because skin feels oily. Dehydrated oily skin often overproduces sebum to compensate; hydration is still essential.
- Using too high a concentration too soon. Start lower if you're new to niacinamide to avoid initial flushing or tingling.
- Expecting pore size to physically shrink. Niacinamide minimizes the appearance of pores rather than changing their actual size.
Quick Questions, Quick Answers
Are there any downsides to niacinamide serums?
Higher concentrations like the SKIN1004 10% ampoule can cause temporary flushing or tingling for those new to the ingredient. Starting with a lower percentage, like the 3% in the Anua serum, is the safer route if you haven't used niacinamide before.
Good for sensitive skin?
Yes, the Anua Rice Ceramide 7 Barrier Serum is the gentlest of the three, formulated to support sensitive or barrier-compromised skin.
Daily use okay?
Yes, all three serums are designed for daily AM and PM use.
How long until I see something?
Most people notice reduced shine and smoother texture within two to four weeks of consistent use.
Can I mix it with vitamin C?
Yes, niacinamide and vitamin C work well together, and the Dr. Althea serum already combines both in one step.
Will it work on oily skin?
Yes, all three options here were chosen specifically for oily and combination skin.
The Takeaway
Niacinamide is one of the most forgiving actives for managing oily skin through a humid Canadian summer, controlling shine without stripping or over-drying. Pair it with a lightweight moisturizer and daily SPF for the best results.
