So a former refugee built a skincare brand on ancestral Korean wisdom. And now everyone’s obsessed with this serum. I get it — but I also side-eyed it for a month before trying.
The founder, Then I Met You, spent years sourcing birch sap from the same Korean forests her grandmother used. That’s not marketing fluff — that’s a real supply chain story. And it shows in how the formula behaves.
🧴 **What’s in the Bottle**
$48. 50ml. Claims to “soothe and hydrate without heaviness.” I’ve heard that before. But the texture made me pause — it’s water-thin but somehow coats your face like a cloud.
1. **Birch Sap (first ingredient)** — not water. It’s naturally rich in minerals and amino acids. Your skin drinks it differently.
2. **Centella Asiatica** — calms redness without that sticky film most calming products leave behind.
3. **Panthenol (B5)** — actually repairs moisture barrier, not just slaps hydration on top.
🔬 **Ingredients That Earn Their Spot**
Hero here is the birch sap — it’s harvested only 2-3 weeks a year when the sap runs. Most brands water it down. This one doesn’t. You get niacinamide for brightness, tremella mushroom for that jelly-like hydration, and squalane to lock everything in.
– Birch Sap: mineral-rich hydration that sinks in fast
– Niacinamide: evens tone without irritation
– Tremella Mushroom: holds 500x its weight in water
– Squalane: lightweight sealant, no greasiness
📖 **The Texture Test**
It’s like water but…thicker? Think slippery silk. Absorbs in about 15 seconds — no joke. First week I thought “nice but nothing special.” Week two my skin stopped drinking toner like it was dehydrated.
What surprised me: it fixed my jawline texture. Those tiny bumps? Gone. Didn’t expect that from a “soothing” serum.
💡 **One Thing** — Apply to damp skin. Pat don’t rub. The birch sap glides better and absorbs twice as fast.
✨ **Did It Actually Work?**
Yes — but only if you need soothing hydration. My redness dropped 60% in three weeks. But my fine lines? Same as before. It’s not an anti-ager. Know what you’re buying.
✅ **Buy if** — you have reactive, dehydrated skin that hates everything
⏭️ **Skip if** — you need heavy anti-aging or acne-fighting actives
💰 **Worth it?** — For the ingredient sourcing alone, yes. But $48 is steep for a serum that’s mostly hydrating.
💧 **Final Take**
It’s a beautifully made hydrating serum for sensitive skin. Overhyped? Slightly. But the birch sap thing is real — my skin’s calmer, smoother, and stops freaking out. That’s worth something.
**8.2/10** — Calm skin, calm wallet? Not quite.
🛍️ **Where to Buy** — Sephora or their site directly. Grab the travel size first ($22) to see if your skin vibes with birch sap.
