Ask a devoted K-beauty follower how they first heard about Dear Klairs, and the answer is almost never a magazine. It is a YouTube video filmed in a Korean apartment, or a Reddit thread in a subreddit dedicated to Asian skincare, or a friend who came back from Seoul with something in their carry-on that they could not stop talking about. The brand built its following before it had a U.S. retail presence, which is a rarer path than it sounds and a more durable one.
That history makes the current moment worth paying attention to. Song of Skin, the TikTok mega-creator who has spent years teaching an American audience how to actually read a Korean skincare routine, is bringing the brand’s Midnight Blue Youth Activating Drop to a New York pop-up this late May. The serum has sold over one million bottles in South Korea and recently took home the 2026 Seoul Awards. It is now about to meet a New York audience that has, in many cases, been following Korean skincare long enough to already know what EGF does.
The Formula Behind the Following
There are serums that sell because of how they look and serums that sell because of what they do. The Blue Drop has managed both, which is partly why it keeps generating the kind of word-of-mouth that sustains long-term sales rather than just launch spikes. The blue color comes from Guaiazulene, a chamomile-derived compound recognized in cosmetic chemistry for its calming properties, giving the formula a visual identity that aligns with the brand’s sensitivity-first approach. The serum looks like it soothes skin because it contains an ingredient known for that effect.
Beneath that surface, the peptide complex does the longer-term work. Sh-Oligopeptide-1, the form of EGF used in the formula, is studied in cosmetic ingredient research for its association with collagen-related pathways and skin renewal. Sh-Polypeptide-1, the bFGF equivalent, is recognized in formulation science for its role in elasticity and skin repair mechanisms. The dual-peptide approach reflects a formulation philosophy of working through multiple pathways at once, consistent with the brand’s focus on barrier-conscious, sensitivity-friendly skincare. “Every ingredient in the Blue Drop earns its place,” said a Wishcompany representative. “The brand’s whole approach to formulation starts with sensitive skin and works outward from there”.
Song of Skin’s New York Audience Is Ready for This
Song of Skin has spent years building something unusual on TikTok, an audience that finds ingredient science genuinely engaging. The creator’s content explains Korean skincare in the kind of practical, accessible terms that make a viewer feel smarter rather than overwhelmed, which means followers arrive at product recommendations already understanding the logic behind them. Bringing the Blue Drop to New York through that platform gives the serum something a conventional press launch rarely delivers. An audience that already understands what it is looking at.
New York’s beauty community has its own particular fluency. This is a city where the Allure offices and the Reddit skincare forums and the independent beauty boutiques in Brooklyn are all having versions of the same conversation, and that conversation has increasingly centered on barrier repair, low-irritation formulation, and the question of what K-beauty actually brings to skin that Western skincare does not. The Midnight Blue Youth Activating Drop is a direct answer to that last question. “When we bring the Blue Drop to New York, we are bringing something that has already been tested by some of the most demanding consumers in the world,” said a Wishcompany representative. “That record speaks before we say a word”.
The Larger Picture Behind a Single Pop-Up
Olive Young, the South Korean health and beauty retailer that holds a dominant position in its home market, is opening its first American physical stores starting May 29 in Pasadena, California, with additional locations in Los Angeles to follow. Dear Klairs is part of that inaugural offline lineup, which means the brand is entering U.S. brick-and-mortar retail at the same moment it is being introduced to New York through one of the platform’s most credible skincare voices.
For Wishcompany, the Seoul-based parent company founded in 2010 and now operating across 80 countries with a combined digital following in the millions, the U.S. push reflects a deliberate sequencing of moves. Build credibility first. Let the product speak through people who understand it. Then put it on the shelf. The New York pop-up is where those threads converge, and the audience showing up will not need a primer on why the serum is worth their attention.
