This $21 eye serum is doing $1.1M/month. The formula is dead simple. They don’t have some fancy brand story. And yet they’re pulling in millions. Here’s what’s inside this tube dominating the K-beauty under-eye category (and how it’s selling over 52,000 units/month:)
1. Ingredient snapshot (per 30ml tube): • Retinal — potent but less irritating vitamin A derivative • Niacinamide — brightens, smooths, reduces pigmentation • Ginseng root extract — circulation boost, antioxidant • Ceramides + cholesterol — barrier support • Panthenol —
2. Production process • Retinal stabilized in gentle emulsion • Ginseng extract infused post-base to maintain potency • pH balanced for eye safety (~6.0) • Filled into airless pump tubes (for oxidation protection) • Batch tested for color, scent, and viscosity
3. Texture & function • Creamy, emollient gel • Melts into skin (no white cast, no pilling) • Used under eyes + on neck (dual-zone targeting) • Reduces puffiness, early wrinkles, and dullness Soft-focus filter for tired skin.
4. Packaging • 30ml opaque tube • Pastel aesthetic, no outer box for some SKUs • Est. packaging cost: ~$0.45–$0.70/unit • Shelf-stable for 12–18 months Feels premium + ships very light. That’s the golden combo.
5. Margins & scale • Retail: $21 • Estimated COGS: ~$2.50–$3.50 • Monthly units: ~52,000 • Monthly revenue: $1.1M • Retail markup: 6–8× Premium actives with mass-market reach.
Why it works: 1. Retinal is hot and ginseng is trusted. 2. Korean brands know how to thread the needle. High-efficacy, low-irritation, mid-price. And because of this, they’ve been racking in bank pretty consistently.
