What Olive Young is (and why it sets the standard)
When people talk about "what works in Korea," one retailer is the compass: Olive Young. Founded in Seoul in 1999, it is by far Korea's number-one beauty retailer: more than 1,380 stores, over 85% of the health-and-beauty store market, and around $4.2 billion in 2025 revenue (5.83 trillion won, up 21.8% year on year).
Why it matters to you: Olive Young's charts and annual Awards are built on the real sales of millions of Koreans, widely seen as some of the most demanding skincare shoppers in the world. These aren't influencer picks, they're sales data. And the trends usually reach the West six to twelve months later, so following them puts you ahead.
The trends rising in 2026
According to Olive Young data, three signals stand out this year:
- Niacinamide: searches up roughly 26% year on year, the most in-demand glow/oil-control active.
- PDRN (from salmon DNA): +90%, the new repair star.
- "Capsule" creams and gel-creams: searches surging (up to +1,379% for "capsule cream"), a shift toward next-generation hydrating textures.

Popular doesn't mean right for YOU
A best-seller in Seoul was designed for Korea's often-humid climate. In Paris or elsewhere in Europe, dry air, indoor heating and hard water change your skin's needs by city and season. A hero product can be perfect for your neighbour and useless for you.
That's exactly what Fiomio does: the free diagnostic crosses your skin type, your concerns and your city's climate to tell you which of these actives truly suit you, and why.
