01 · Market
PDRN is proven in Korea and still open in the U.S.
trendier AI tracked PDRN across Olive Young, Amazon U.S. and Sephora for six months. On Olive Young, the top five brands' share fell from 54.7% to 36.3% as new labels arrived, and PDRN spread into 42 sub-categories from toners to body care. That is a category still adding sellers, not one closing up.
The U.S. picture is different. One brand holds 88.57% of PDRN on Amazon U.S., the price sweet spot sits between $15.81 and $25.00, and Sephora went from one PDRN product to nine in early 2026. Shoppers there have mostly met PDRN through a single hero product, which leaves room for a second and third story.
Demand is also widening. Spate counts PDRN conversations tied to mature skin at 15,000 a month, and PDRN paired with fine lines at 12,900, each up more than 1,000% year over year.
02 · Competition
Who shoppers compare it with
Most PDRN serums a shopper will see next to this one fall into two groups: salmon-DNA serums that made the trend famous, and a smaller set of plant-based ones. Price bands are close, so the source of the PDRN and the second active become the real differences on the shelf.
| Product | PDRN source | Second story | U.S. price |
|---|---|---|---|
| M Brand | Salmon DNA | Peptides, niacinamide | $22 · 30 mL |
| A Brand | Salmon DNA | Hyaluronic acid and collagen | $30 · 30 mL |
| R Brand | Salmon DNA | Salmon PDRN | $52 · 30 mL |
| Dear, Klairs Vitamin PDRN Bouncy Pore Serum | Plant, 3 types | 5 types of vitamin C plus peptides; pore focus | $23 · 35 mL |
03 · Where Klairs fits
Plant PDRN at a mass price, with vitamin C
Against that shelf, Vitamin PDRN Bouncy Pore Serum sits in a small gap. Where the category leaders build on salmon-derived PDRN, this one uses three plant-based PDRNs from rice, from ginseng and from a probiotic ferment so it carries no fish-allergen question and holds a vegan claim. Those sit alongside five forms of vitamin C and a peptide complex, in a 35 mL bottle at $23 on the Dear, Klairs U.S. store.
The formula is also the brand's answer to a specific complaint about PDRN and vitamin C together: that the pairing stings. Klairs stabilised the vitamin C, ran sensitive-skin testing and positions the serum for twice-daily use. The clinical claim is narrow and concrete nine pore measurements, from count and area to elasticity, in a human-use test.
The serum has already done its proving in Asia. It launched in Japan in January 2026 and took the No. 1 spot in Qoo10's official cosmetics category within the month, then held a 4.6 average across roughly 2,000 reviews by July. A single creator video explaining the plant-derived PDRN passed a million views across Instagram and TikTok. Repeat purchase shows up in the reviews themselves buyers who have gone back more than once, who now buy it as a gift, who note it is light enough to use morning and night.
Videos
Nine Japanese creators, one serum on camera
9 creator videos · 7 YouTube, 2 TikTok
Every video here shows the Vitamin PDRN Bouncy Pore Serum itself and passed our reach check: more than 10,000 views, 300+ likes and comments. Cards are ordered by views within each platform. Sponsored ties are labeled where the video or caption discloses them, and one critical review is included on purpose.
What the videos say: creators praise the watery gel texture and low irritation, and the serum keeps showing up in Qoo10 Mega Wari picks. The critical EGA.channel review questions how much of each headline ingredient is in the bottle. Buyers should expect that question from informed shoppers and answer it with the brand's full ingredient list.
04 · Where it is selling
Japan and Southeast Asia are already buying
- Japan. The serum is a regular in Qoo10 Mega Wari coverage. 386,523-view Mega Wari picks video names it among the must-buys,and a 139,923-view Qoo10 sale video features a Klairs PDRN set including the serum. Nine Japanese creator videos in this brief show the bottle on camera. Japanese shoppers already know PDRN through various brands, so the serum competes on the same page.
-
Southeast Asia. The Vitamin PDRN serum is driving sustainable growth across Southeast Asia. In Singapore, creator-led TikTok campaigns capture impulse buyers, while the official Shopee store engages research driven consumers.
Expanding into the Philippines and Malaysia via Shopee live commerce, this localized approach delivers robust customer retention. Ultimately, the serum has cemented its position as a reliable steady seller, securing long-term shelf space through organic repeat purchases rather than aggressive discounting.
Both markets have heavy PDRN competition and still made room for a plant-based option. In Japan the coverage is broad rather than viral: sale roundups, sensitive-skin routines, men's pore care.
05 · How to sell it
Shelve it beside the leaders, not away from them
- Shelf. Put it in the PDRN bay next to the salmon-based serums, with a short "plant PDRN + vitamin C" shelf talker.
- Product page. Lead with "salmon-free PDRN" and the price. Add a comparison line for shoppers who already know salmon PDRN.
- Staff line. "If you like the PDRN trend but not the salmon, this is the plant version, with vitamin C."
- Sampling. WishTrade lists a 2 mL sample next to the 35 mL size, which suits a trial-first launch.
