Why These 5 Korean Skincare Products Outsold the Rest: Unexpected Insights from May 19–26
Every week, we see trends. But sometimes, what sells the most isn’t just about popularity — it’s about timing, science, and that subtle shift in what customers are truly looking for.
From May 19 to May 26, these five products weren’t just top sellers — they stood out by solving real skincare dilemmas in smart, thoughtful ways. Here’s why your customers might be obsessing over them, and how you can use that to boost your own wholesale strategy.
1. KSECRET [In-Stock] SEOUL 1988 Eye Cream – Retinal Liposome 4% + Fermented Bean
Why it’s selling:
We’re seeing a shift: customers don’t want “gentle” for the sake of it — they want effective. This eye cream is loaded with Retinal (4%!) — a powerful but tricky ingredient to stabilize. But the genius here is in the delivery: liposomes + fermented bean extract make it potent and skin-friendly. Add that to a minimalistic, Seoul-inspired aesthetic? You’ve got Gen Z’s dream eye treatment.
Tip for wholesalers: Position this as a high-performance, high-concept anti-aging solution for younger skin — especially for nighttime routines.
2. KSECRET SEOUL 1988 Serum – Retinal Liposome 2% + Black Ginseng
Why it’s selling:
Not all Retinal products are created equal. This serum is part of a smart duo with the eye cream above, making it easier for consumers to build a routine. But the secret sauce? Black ginseng. It’s not just trendy — it adds antioxidant depth and storytelling power. This is a “serum with heritage,” and savvy shoppers love that.
Tip for wholesalers: Sell this as a gateway for customers who are ready to graduate from Vitamin C to Retinal — but want something rooted in Korean tradition.
3. BEAUTY OF JOSEON Relief Sun Aqua Fresh – Rice + B5
Why it’s selling:
This isn’t a surprise, but here’s what’s changed: customers are no longer settling for greasy, heavy sunscreens — and Relief Sun ticks all the boxes for 2024. It's reef-safe, featherlight, hydrating, and makeup-friendly. B5 and rice extract make it soothing enough for sensitive skin — a big plus as more users incorporate exfoliants and actives into their routines.
Tip for wholesalers: Stock up before summer kicks in across the Northern Hemisphere — this will fly off your shelves as SPF demand spikes.
4. EQQUALBERRY Vitamin Illuminating Serum
Why it’s selling:
This serum doesn't just promise glow — it delivers visible brightness fast. Why? Because it's not just Vitamin C — it's a mix of niacinamide, glutathione, and other antioxidants that work in synergy. The texture is ultra-absorbing, and the branding feels both modern and trustworthy — especially in markets where customers are tired of overhyped serums that don’t show results.
Tip for wholesalers: Highlight this as a “real results” brightening serum — ideal for those who want more than just a dewy look.
5. EQQUALBERRY Bakuchiol Plumping Serum
Why it’s selling:
Retinol lovers are everywhere — but retinol sensitive skin is even more common. That’s where this serum wins. Bakuchiol offers a gentle but clinically proven alternative. What makes this one different is its firming, plumping effect, which makes it more than just a retinol dupe — it’s a full-on skin renewal booster, safe for daily use.
Tip for wholesalers: Great for night-time skin cycling routines or retinol-free offerings for sensitive-skin customers.
Final Thoughts:
It’s easy to assume that best-sellers are all about marketing hype — but the real story here is ingredient literacy. Customers are reading labels, watching ingredient breakdowns on TikTok, and choosing smarter.
As a wholesaler, riding these trends means more than just stocking the right products. It means understanding why they’re resonating — and using that knowledge to tell a better story to your customers.
