Niacinamide is everywhere right now. Every other serum, moisturiser, and toner seems to contain it, which is either reassuring or exhausting depending on how you feel about skincare trends. The good news is that the hype is justified – it’s one of the better-researched ingredients in cosmetics. The interesting bit is how differently Korean and Japanese brands use it.
What Niacinamide Actually Does
Vitamin B3, to use its less exciting name, does a lot: brightens uneven skin tone, minimises the appearance of pores, regulates sebum, supports the skin barrier, and has some anti-inflammatory properties. It’s also stable, well-tolerated by most skin types, and plays nicely with almost everything else in a routine. This is why everyone puts it in everything.
The Korean Approach: Turn It Up
K-beauty tends to use niacinamide at higher concentrations and lead with it. It’ll be front and centre in the marketing, often at 5-10%, and the product is frequently built around it as the hero ingredient. The Beauty of Joseon Glow Serum is a good example – niacinamide paired with propolis, positioned as a brightening treatment. You know exactly what you’re getting and why.
The Japanese Approach: Let It Work Quietly
Japanese formulations tend to use niacinamide as part of a broader formula rather than the headline act. It’s there, it’s doing its job, but the product isn’t shouting about it. Melano CC is a good example – vitamin C leads, niacinamide supports. The focus is on what the formula achieves overall rather than any single ingredient.
Which Approach Is Better?
Neither – they suit different people. If you want a targeted brightening treatment and like knowing exactly what’s doing the work, the Korean approach is more satisfying. If you’d rather have a formula that just quietly improves your skin without requiring you to think about percentages, Japanese skincare is more your speed.
Both work. The ingredient is the same. It’s really just about how much you want to be involved.
