Learn how to use 10% niacinamide serum for minimizing pores. Step-by-step routine tips, frequency, layering, and best Naturium products to pair.
If you've been searching for a way to refine your skin's texture and visibly reduce the look of pores, 10% Niacinamide Serum is likely on your radar. This powerhouse ingredient has earned a cult following for its ability to balance oil, support a healthy skin barrier, and improve the appearance of pore size over time. But knowing how to use it correctly makes all the difference between glowing results and potential irritation.

In this guide, we'll walk you through exactly how to incorporate a 10% niacinamide serum into your daily routine, how often to apply it, and which Naturium products pair beautifully with it to maximize pore-minimizing benefits.
What Is 10% Niacinamide and How Does It Minimize Pores?
Niacinamide, also known as vitamin B3, is a multi-tasking skincare ingredient that works in several ways to improve the look of pores. At a 10% concentration, it's potent enough to visibly reduce the appearance of enlarged pores by helping to regulate sebum production. When your skin produces less excess oil, pores look smaller and less congested.
Additionally, niacinamide supports the skin's natural barrier, which helps retain moisture and reduces inflammation. This is key because dehydrated or irritated skin often looks dull and can make pores appear more prominent. By strengthening the barrier, niacinamide helps your skin look plumper and smoother, which in turn makes pores less noticeable.
For best results, consistency is crucial. You won't see dramatic changes overnight, but with regular use over several weeks, you'll notice a refined texture and a more even appearance.
- Regulates excess oil production
- Strengthens the skin barrier
- Visibly reduces pore size over time
How to Apply 10% Niacinamide Serum: Step-by-Step
Proper application ensures you get the most out of your niacinamide serum without irritation. Start with a clean face. After cleansing, gently pat your skin dry—niacinamide works best on slightly damp skin, but it's fine if your skin is completely dry.
Dispense 2-3 drops of the serum onto your fingertips and press it into your face and neck. Avoid rubbing vigorously. Allow the serum to absorb for about 30 seconds before moving on to the next step in your routine. This prevents pilling and ensures the serum can penetrate effectively.
If you're using other active ingredients like exfoliants or retinoids, layer niacinamide after water-based serums and before heavier creams or oils. Niacinamide is generally well-tolerated and can be used alongside most ingredients, but it's always smart to introduce one new active at a time to monitor your skin's response.
- Use 2-3 drops for the entire face
- Apply after cleansing and before moisturizer
- Wait 30 seconds for absorption before layering
How Often Should You Use Niacinamide for Pores?
For most skin types, using a 10% niacinamide serum once or twice daily is safe and effective. If you're new to niacinamide, start with once a day, preferably in the evening, to let your skin adjust. After a week, you can increase to twice daily—morning and night—if your skin tolerates it well.
Because 10% is a higher concentration, some people with very sensitive skin may experience mild flushing or irritation. If that happens, reduce frequency to every other day or mix a drop of serum with your moisturizer to dilute it. The goal is to maintain consistent use without overwhelming your skin.
Remember, niacinamide is not a quick fix. For pore minimization, you'll want to use it consistently for at least 4-6 weeks to see noticeable improvements. Pair it with a gentle cleanser and a good moisturizer to support your skin's barrier.
- Start with once daily, then increase to twice if tolerated
- If irritation occurs, reduce to every other day
- Consistency over 4-6 weeks yields best results
Best Naturium Products to Pair with Niacinamide for Pores
To get the most out of your niacinamide serum, choose complementary products that support oil control and barrier health. A gentle, non-stripping cleanser is essential. The Glycerin Gentle Purifying Cleanser from Naturium is an excellent choice—it cleanses without disrupting your skin's moisture barrier, making it the perfect first step before applying your serum.

After your serum, lock in hydration with a lightweight moisturizer. The Vitamin B, C and E Moisturizer is formulated to nourish and protect the skin, providing the perfect finishing touch. It works in harmony with niacinamide to keep your skin balanced and comfortable.
If you're dealing with blackheads or congestion alongside large pores, consider adding a salicylic acid cleanser to your routine a few times a week. The Salicylic Acid Cleanser - 150ml helps exfoliate inside the pore, while niacinamide works on the surface. Use them at different times of day to avoid over-exfoliation.
- Glycerin Gentle Purifying Cleanser: gentle, hydrating cleanse
- Vitamin B, C and E Moisturizer: barrier support and nourishment
- Salicylic Acid Cleanser: deep-clean pores 2-3 times a week
Common Mistakes to Avoid When Using Niacinamide
One common mistake is using too much product. More serum doesn't equal better results—it can lead to pilling and potential irritation. Stick to a pea-sized amount for your entire face.
Another mistake is layering niacinamide with other potent actives like strong acids or retinoids in the same routine without proper buffering. While niacinamide is generally compatible, it's wise to separate strong exfoliants to different times of day or alternate days to prevent over-sensitizing your skin.
Finally, don't skip sunscreen. Niacinamide can make your skin more sensitive to the sun, especially when combined with other actives. Always apply a broad-spectrum SPF in the morning to protect your skin and prevent further pore enlargement from sun damage.
- Avoid over-application; a pea-sized amount is enough
- Don't combine with strong acids in the same routine
- Always wear SPF during the day
Incorporating 10% niacinamide serum into your daily routine is a smart, effective way to minimize pores and achieve a smoother, more refined complexion. By following the steps above and pairing it with the right Naturium products, you'll be well on your way to visibly improved skin. Start with the Glycerin Gentle Purifying Cleanser to prep your skin, apply your niacinamide serum, and finish with the Vitamin B, C and E Moisturizer for optimal results.
