Niacinamide: The Korean Skincare
Ingredient Everyone Should
Be Using
Niacinamide does more for your skin than almost any other single ingredient — and it's safe for every skin type. Here's the complete guide to using it correctly.

What is Niacinamide?
Niacinamide is a form of Vitamin B3 — a water-soluble vitamin found naturally in many foods and used as a potent skincare active. It has been studied extensively in clinical dermatology for decades, and the evidence for its skin benefits is among the strongest of any topical ingredient.
What makes niacinamide exceptional in Korean skincare is not just its efficacy — it's its versatility and safety profile. Unlike retinol (which requires careful introduction), vitamin C (which can be unstable), or AHAs (which require sun protection), niacinamide can be used morning and evening, by all skin types, including pregnant women, and alongside virtually every other active.
Niacinamide (vitamin B3) is a water-soluble skincare active that reduces enlarged pores, fades dark spots, controls sebum, strengthens the skin barrier, and reduces inflammation. It is beginner-safe, suitable for all skin types, and can be used twice daily in both morning and evening routines. It is one of the most clinically supported ingredients in modern skincare.
What Does Niacinamide Actually Do?
How to Use Niacinamide Correctly
Where in your routine: Apply niacinamide as a serum or toner after cleansing, before moisturiser. It absorbs quickly and layers well with everything that follows.
Morning or evening? Both. Unlike retinol or AHAs, niacinamide has no restrictions on when it's used. Consistent daily use gives the best results.
What concentration? Beginners should start at 5% or below. Products at 2–5% are effective for most concerns and gentle enough for daily use by all skin types. 10%+ concentrations are available but can cause temporary flushing in some skin types — not harmful, but worth starting lower.
How long until results? Pore and oil control improvements often appear within 2–4 weeks. Visible lightening of dark spots typically takes 8–12 weeks of consistent use.
Beginner tip: Niacinamide is one of the best first serums to introduce in your routine. Read our week-by-week plan in the Beginner's Guide to know exactly when to add it.
What to Mix With Niacinamide (And What to Avoid)
- Hyaluronic acid
- Ceramides
- Vitamin C (the incompatibility myth is debunked)
- Retinol (use in the same routine or alternate)
- SPF (excellent morning companion)
- AHA / BHA (use in the same routine)
- Peptides
- Very high-strength Vitamin C (20%+) — may cause temporary flushing in sensitive skin; separate by AM/PM if concerned
- Extremely acidic formulas at pH below 3 — may slightly reduce niacinamide efficacy if applied simultaneously

Frequently Asked Questions
Niacinamide (vitamin B3) is a multitasking active that reduces enlarged pores, fades hyperpigmentation and dark spots, regulates sebum production, strengthens the skin barrier by boosting ceramide synthesis, reduces redness and inflammation, and improves overall skin texture. It is suitable for all skin types and is considered one of the most versatile and research-backed actives in modern skincare.
Yes. The old claim that niacinamide and Vitamin C cannot be used together has been disproven by modern research. Both can be applied in the same routine without adverse effects. If you prefer to separate them, use Vitamin C in the morning (where it boosts SPF effectiveness) and niacinamide morning and evening — but separation is not required.
For beginners and sensitive skin, start with products containing 2–5% niacinamide — this is effective for most skin concerns and very well tolerated. Products at 10% are available and used for more pronounced oil control or pore concerns but may cause temporary flushing in some skin types. Begin with a lower percentage and build up.
Apply niacinamide as a serum after cleansing and before moisturiser. It can be used in both morning and evening routines. Unlike retinol or acids, niacinamide has no timing restrictions — consistent daily use (morning and evening) gives the best cumulative results.
