01 · Why now: the Korean signal

It became a bestseller in Korea before it became a trend abroad

In Korea, the Blue Youth Activating Drop ranked #1 in Olive Young's online skincare category in 2024, and the line entered every Olive Young store nationwide in April 2026, according to Wishcompany's buyer guide.[1] The brand describes it as a serum that sells one bottle every four seconds at Olive Young, a claim that sits on its U.S. product page.[2]

That matters for a buyer because the product is not a new launch looking for its first audience. Korean shoppers have already done the testing.

02 · Global trend match

Growth factors are what skincare media is talking about

Epidermal growth factors have moved into mainstream Western beauty coverage. Marie Claire describes EGFs as trending for their skin-repairing reputation,[3] and Allure now runs a dedicated guide to growth-factor serums.[4]

Most of that coverage features premium, clinic-adjacent brands. Blue Youth Activating Drop gives shoppers the same ingredient conversation in a Korean first-serum format.

• Creator reach: Blue EGF creator content has passed 150 million views, according to campaign information published by WishTrade.
• Offline proof: The brand ran a New York pop-up with Song of Skin in May and June 2026 and an LA pop-up with Hapa Kristin in September 2026.
• Retail proof: Dear, Klairs entered Olive Young's first U.S. store in Pasadena in May 2026.

03 · What sets it apart

A formula shoppers can see, and a spec they can repeat

The label reads EGF 10 ppm, with guaiazulene and adenosine. WishTrade's product news lists EGF (sh-Oligopeptide-1) 10 ppm, bFGF (sh-Polypeptide-1) 10 ppm and guaiazulene 1,000 ppm.[5] The brand states that 10 ppm is the highest EGF concentration allowed by Korea's MFDS.[2]

Guaiazulene turns the serum blue. That one detail explains a lot of its social performance: a blue drop is recognizable in a three-second clip, and shoppers remember it when they see it on a shelf.

• Texture : Watery first serum, used after cleansing
• Positioning: Calming care and early anti-aging
• Naming: Earlier creator videos call it Midnight Blue Youth Activating Drop

04 · Where the opportunity is

Three markets where the Blue EGF story already has traction

• United States. Creator-led demand, two brand pop-ups in 2026 and an Olive Young store presence give U.S. retailers a story shoppers have already seen online.
• Singapore. Blue Drop has quickly become the best-selling product in the Klairs lineup on Shopee Singapore and broken into the platform's Top 10 serums overall, and that traction is now drawing offers and partnership opportunities from multiple offline retailers.
• Japan.  A No. 1 overall Qoo10 ranking on Blue Drop's 50ml debut, a No. 2 beauty-set and No. 7 overall finish in the August Megawari with the Rilakkuma set, and expanding shelf space across Don Quijote, Hands and other variety-shop chains show demand converting from online to offline.

05 · The line behind the hero

One serum opens a whole blue shelf

The serum does not have to stand alone. WishTrade lists the wider Dear, Klairs Blue line, including Blue EGF Intensive Pro Cream, Blue EGF Calming Mist, Blue EGF Calming Gel Mask, Blue EGF Barrier Lip Balm and Midnight Blue Calming Cream.[9] Wishcompany reports distribution across more than 10,000 online and offline channels in over 70 countries.[1]

The brand's own routine card gives staff a simple way to sell a second item: pair the serum with a calming cream for redness-prone skin. The full usage steps are in WishTrade's EGF guide.[10]

06 · How to merchandise it

Let the blue do the selling

• Shelf. Build a small blue block: the serum at eye level, with the calming cream and mist beside it. The color makes the set readable from across the store.
• Product page. Open with a dropper shot of the blue serum and one creator clip. Keep the 10 ppm spec and the brand's claims attributed.
• Staff line. "Korea's best-known EGF serum. A few drops after cleansing, then your usual routine."
• Bundle. Offer the serum with a calming cream for redness-prone shoppers, following the brand's own routine card.

A suggested four-week retail test. No sell-through outcome is implied.

07 · Buyer questions

What buyers usually ask before a Blue EGF order

• Is the trend already peaking? The line is still adding retail doors and pop-ups in 2026. Buyers who stock before local creators pick it up tend to benefit most.
• Why are there two product names? Earlier creator videos call it Midnight Blue Youth Activating Drop. The current name is Blue Youth Activating Drop.
• Which second SKU should we add? Start with a calming cream, then consider the mist or gel mask once the serum sells.
• What about price, stock and lead time? Those are shared after account approval through WishTrade.
