PDRN searches are up 811%. The shelves haven't caught up.
The salmon-DNA ingredient is the fastest-heating signal on our radar this week: US search demand has multiplied 9x year over year, while PDRN products hold just 7 chart slots across the 15 retail channels we track.
Every week we cross two things: what people search for, and what actually ranks on shelves. Most ingredients move together. PDRN is not moving together.
US search demand for PDRN sits around 61,000 monthly searches, up +811% year over year — and the single query “pdrn serum” is up roughly +900% on its own. That is the steepest demand curve of any ingredient on our radar this week.
The shelf is lagging the search bar
Across the 15 channels we track, PDRN products hold 4 chart slots in Korea and 3 in the US — seven placements total, against a demand curve that has multiplied nine-fold. Compare Hyaluronic Acid: 110K searches, barely growing, and 9 slots. Mature demand, mature shelf. PDRN is the opposite: young shelf, exploding demand.
Who's positioned if the storm lands
The clearest early mover is Anua — its PDRN Hyaluronic Acid Capsule 100 Serum climbed to #11 on Hwahae Global's review-trust ranking this week (▲2), and Anua already has the widest channel reach of any brand we track (11 of 15 channels). When a brand with distribution muscle owns a heating ingredient, the migration usually follows.
What we'll watch next
Ingredient Weather runs every Thursday. For PDRN, the tell will be simple: does the US slot count move from 3 — and which channel moves first? Specialists (Skin Cupid, Soko Glam) usually blink before prestige and mass. When it happens, it will be in the Rank Movers board the same week.
