I bought the original CAIS on a whim in 2019 and it ruined me for other serums. The new 2:1 version? It’s not the same — and that’s both good and annoying.
Your skin doesn’t just feel bouncy after a week. It feels *thicker*. Like you accidentally gave it a pump class.
Niod calls this a “next-gen” copper peptide serum. $88 for 30ml. The claim that got me: it’s the first to combine two copper complexes at a precise 2:1 ratio. Sounds like science fluff — but I’m a sucker for ratios.
Dual Copper Complex
Two types of copper peptides instead of one — targets surface and deeper layers simultaneously
No Slime Texture
Original CAIS felt like snail goo. This one dries in 20 seconds flat.
Bottle Upgrade
Pump actually works now. No more stabbing the dropper into a half-empty bottle.
Three actives doing real work, plus a surprise fourth that sounds boring but isn’t. No filler oils or trendy extracts here — just concentrated peptides and a hydration booster that actually matters.
- Copper Tripeptide-1: Boosts collagen production — not just a buzzword
- Copper PCA: Antioxidant that calms redness while you sleep
- Palmitoyl Tripeptide-38: Firms saggy jawline area specifically
- Propanediol: Sounds chemical — actually helps everything absorb without stickiness
Watery. Slightly blue. Smells like nothing — which I respect. Absorbs before you finish rubbing it in. No pilling under moisturizer, which is rare for peptide serums.
Week two: my pores looked… smaller? Not gone, but like they’d been told to sit down. Week three: a zit healed in two days instead of five. That’s the copper doing wound repair — unexpected win.
Fine lines around my mouth softened — not erased, but less angry. Skin tone more even. One weird thing: my under-eye area looked brighter, even though this isn’t an eye serum. Collagen boost doesn’t know boundaries.
Worth the hype and the price — if you’re patient. This isn’t a quick fix; it’s a six-month investment in not looking tired.
