Glass Skin Guarantee

🔒 Glass-Skin Guarantee

We believe in results you can see — and feel. That’s why every order from The Korean Skin Co. is backed by our Glass-Skin Guarantee. If you’re not absolutely glowing after your first use, we’ll refund your order — no questions asked (just a few simple steps below).


Bio-Collagen Face Masks ✨

Not seeing that radiant, glass-like glow?

  1. 📸 Take a clear photo of your face before applying the mask, with a visible watch or timestamp.
  2. 📷 Snap one photo every 30 minutes during the 4-hour wear (8 photos total) with your face and the time clearly visible.
  3. 🎥 Record a short video of yourself removing the mask after the full session.

If you’re not satisfied with the results, just return any unused masks and we’ll issue a full refund.


Bio-Collagen Eye Patches 👁️

Under-eyes not visibly brighter?

  1. 📸 Take a photo of your under-eye area before applying the patches, with a visible watch or timestamp.
  2. 📷 Take a photo every 30 minutes for 4 hours (8 photos total), showing the patches in place and the time.
  3. 🎥 Film a short clip of yourself removing the patches after the session.

Not impressed with the results? Ship back any unused patches and we’ll refund you in full.
