Niacinamide vs Vitamin C — Which is Right for You?
Share
Walk into any Korean skincare aisle and you'll spot two ingredients everywhere: Niacinamide and Vitamin C. Both promise brighter, more even skin — but they work very differently. Here's how to choose.
What is Niacinamide?
Niacinamide (Vitamin B3) is a gentle, multi-tasking ingredient that:
- Minimises the appearance of pores
- Reduces dark spots and hyperpigmentation
- Controls excess oil and shine
- Strengthens the skin barrier
- Calms redness and irritation
Best for: Oily, acne-prone, sensitive, or combination skin. Great for beginners.
Try: Anua Peach 70% Niacinamide Serum or COSRX The Niacinamide 15 Serum.
What is Vitamin C?
Vitamin C (Ascorbic Acid) is a powerful antioxidant that:
- Brightens dull skin and evens skin tone
- Fades dark spots and sun damage
- Boosts collagen production
- Protects against environmental damage
Best for: Dull skin, sun damage, ageing concerns, or anyone wanting a radiant glow.
Try: Beauty of Joseon Glow Serum: Propolis + Niacinamide (a gentle hybrid option).
Can You Use Both Together?
Yes! Contrary to old advice, niacinamide and vitamin C can be used together. Use vitamin C in the morning (it pairs well with SPF) and niacinamide morning or night.
Which Should You Choose?
| Concern | Choose |
|---|---|
| Large pores, oiliness | Niacinamide |
| Dullness, uneven tone | Vitamin C |
| Acne marks | Niacinamide |
| Sun damage | Vitamin C |
| Sensitive skin | Niacinamide |
| Anti-ageing | Vitamin C |
Still unsure? Start with niacinamide — it's gentler and works for almost every skin type.
