If you’re researching skincare ingredients that truly deliver, chances are “The Ordinary niacinamide serum” has come up. This product is one of the most talked-about serums in the beauty world — known for its affordability, effectiveness, and versatility.

  • How to use it (and what to avoid)

  • Common questions and answers

 

1. What Is Niacinamide & Why It’s Popular

Niacinamide (a form of vitamin B3) is one of the more research-backed skincare actives. It offers multiple skin benefits without being overly aggressive

Key benefits:

  • Improves skin texture and helps minimize the appearance of pores

  • Helps regulate sebum (oil) production, making it useful for oily or combination skin 

  • Strengthens the skin barrier and reduces moisture loss (thus helping with hydration) 

  • Reduces redness and supports an even tone (soothes sensitivity) 

  • Works well alongside many other actives (vitamin C, retinoids) when layered properly 


2. Spotlight: The Ordinary Niacinamide 10% + Zinc 1%

One of the most well-known niacinamide products is The Ordinary Niacinamide 10% + Zinc 1% serum.

Formula & Purpose:

  • Contains 10% niacinamide and 1% zinc PCA (zinc helps support anti-inflammatory and oil control

  • The formulation is water-based and lightweight, so it absorbs well without heaviness 

  • Targets concerns like blemishes, congestion, uneven texture, visible shine, and dullness 

Pros:

  • Very affordable compared to many high-end serums 

  • Effective for many skin types, especially oily, combination, blemish-prone, or textured skin

  • Minimalist ingredients list, which lowers the chance of irritation for many user

Cons / Considerations:

  • Some users report a slight tingling or stinging, especially when new to it or applied on damp skin 

  • Because it’s an active ingredient, layering improperly with strong acids or retinoids can cause irritation if not spaced correctly 

  • Over time, the formula may feel slightly sticky for some, requiring a good moisturizer on top 

Results Timeline:
Many users begin to see improvements in texture, oil control, or radiance within 4 to 6 weeks of consistent use.

3. How to Use & Layer The Ordinary Niacinamide Serum

Getting the layering order and usage right is key to maximizing its benefits. Here’s a step-by-step guide:

Morning Routine

  1. Cleanse (gentle, pH-balanced)

  2. Apply The Ordinary Niacinamide 10% + Zinc 1% (2–3 drops) on dry or slightly damp skin

  3. Wait ~30 seconds to let it absorb

  4. Follow with a moisturizer

  5. Finish with broad-spectrum sunscreen (SPF)

Evening Routine

  1. Cleanse

  2. Use niacinamide serum

  3. Apply your next actives (retinoids, peptides, etc.) — but if combining strong actives, allow buffer time

  4. Moisturizer last

Tips when layering:

  • Avoid applying strong acids (e.g. glycolic, AHAs) right before or after without spacing time

  • If using vitamin C, some users alternate (vitamin C in morning, niacinamide in evening) 

  • Always patch-test first (inside jawline or behind ear)

  • Don’t overdo it: more serum doesn’t always mean better results

4. Frequently Asked Questions 

4.1 Does niacinamide lighten dark spots or hyperpigmentation?

Yes, niacinamide helps reduce the transfer of melanin to skin cells, which can fade post-acne marks and dark spots over time. Consistent usage is key.

4.2 Can I use The Ordinary niacinamide with retinol?

Yes — you can, but it’s safer to alternate or buffer. For example, apply niacinamide first, wait, then apply retinol, or use them on different nights. This reduces potential irritation.

4.3 Is niacinamide good for dry skin too?

Yes. While many users are drawn to niacinamide for oil control, it also supports the skin barrier and helps retain moisture, meaning it can benefit drier skin types if followed by a proper moisturizer.

4.4 What happens if I use too much?

Overuse may lead to mild irritation, redness, or stinging, especially for sensitive skin. Always use the recommended amount and patch-test. 

4.5 When will I see results?

Many people notice smoother texture, brighter skin, or reduced oil within 4–6 weeks. But deeper issues (e.g. persistent discoloration) may take longer
