What Is Niacinamide?
Niacinamide, also known as vitamin B3 or nicotinamide, is one of the most well-researched and versatile ingredients in skincare. It’s a water-soluble vitamin that works across virtually every skin type and concern, from oily and acne-prone to dry and ageing. It’s no wonder Korean skincare brands feature it in everything from toners to sunscreens.
Unlike many active ingredients, niacinamide is remarkably gentle. It doesn’t cause sun sensitivity, doesn’t thin the skin, and rarely causes irritation — making it an ideal starting point if you’re new to Korean skincare actives.
What Does Niacinamide Do for Your Skin?
- Controls Oil Production: Niacinamide regulates sebum output, making it a star ingredient for oily and combination skin types. Studies show a noticeable reduction in oiliness within 2–4 weeks of regular use.
- Minimises Pores: By keeping pores clear and reducing excess oil, niacinamide makes pores appear visibly smaller over time.
- Fades Hyperpigmentation: It inhibits melanin transfer to skin cells, which means it effectively fades dark spots, acne marks, and uneven skin tone. This is especially valuable for darker skin tones prone to post-inflammatory hyperpigmentation.
- Strengthens the Skin Barrier: Niacinamide boosts ceramide production, reinforcing the skin’s protective barrier. A stronger barrier means less moisture loss and better resilience against irritants.
- Reduces Redness and Inflammation: Its anti-inflammatory properties make it helpful for rosacea, acne, and general skin sensitivity.
- Anti-Ageing Benefits: By stimulating collagen production, niacinamide helps improve skin elasticity and reduce fine lines with consistent use.
Niacinamide Concentrations: How Much Do You Need?
Not all niacinamide products are equal. The concentration matters:
- 2–5%: Ideal for sensitive skin or beginners. Effective for barrier support and mild brightening.
- 5%: The sweet spot for most people. Backed by the most clinical research. Great balance of efficacy and tolerability.
- 10%: Stronger results for oil control and hyperpigmentation, but may cause mild irritation in sensitive skin. Build up to this concentration gradually.
- Above 10%: Not necessarily more effective and can increase the risk of irritation. More isn’t always better.
What to Pair with Niacinamide
Niacinamide is one of the most compatible actives in skincare. It pairs beautifully with:
- Hyaluronic acid: Hydration plus barrier strengthening — a perfect combo.
- Snail mucin: Together they deliver deep hydration, repair, and brightening.
- Centella asiatica: Both are soothing and barrier-friendly. Excellent for sensitive skin.
- Retinol: Niacinamide can buffer retinol’s irritation while delivering complementary benefits.
- SPF: Niacinamide boosts the protective effects of sunscreen.
Who Should Use Niacinamide?
The short answer: almost everyone. It’s especially beneficial for:
- Oily and acne-prone skin (oil control + anti-inflammatory)
- Hyperpigmentation and uneven skin tone (melanin regulation)
- Ageing skin (collagen + barrier support)
- Sensitive skin at lower concentrations (barrier repair + soothing)
