Niacinamide vs Vitamin C — Which is Right for You?

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?

Still unsure? Start with niacinamide — it's gentler and works for almost every skin type.
