Everyone’s selling peptides these days. Most are 1% dust sprinkled in for the label. This one actually does the math.
Medik8 threw three signal peptides at your skin in percentages that matter. It’s basically a wake-up call for collagen—no irritation, just instructions.
It’s $79 for 30ml. Not cheap, but cheaper than the Botox alternative it’s trying to delay. The claim that got me? “Clinically proven to reduce wrinkle depth in 28 days.” I rolled my eyes, then added to cart.
Triple Peptide Stack
Three different peptides—not one—so you’re hitting collagen production, skin firming, and elasticity in one go.
Proven Percentages
The copper peptide is at 1%—that’s the sweet spot for actually doing something, not just looking pretty on the INCI list.
Retinol Alternative
It’s giving retinol results without the purge or peeling. Your skin gets the memo without the tantrum.

This isn’t a kitchen sink formula. It’s a targeted strike on the aging process. The hero trio works together to rebuild the scaffolding your skin loses starting in your late 20s.
- Palmitoyl Tripeptide-38: Tells skin to make more collagen, stat
- Copper Tripeptide-1: Calms inflammation while boosting repair
- Palmitoyl Tetrapeptide-7: Fights glycation—that’s the sugar damage you didn’t know was aging you
- Hyaluronic Acid: Drags water in so those peptides can actually move and work

Texture is a liquid-gel hybrid. Absorbs in 10 seconds flat—no tacky film, no waiting 20 minutes before moisturizer. You can literally feel it disappearing into skin. Wild.
Week two: I forgot I was testing it. That’s the sign. No irritation, no breakouts. Then week three, my jawline looked… defined? Like someone tightened a drawstring. Weirdest thing.

Fine lines around my mouth are softer. Not gone—I’m not lying to you—but they look blurred, like someone turned down the contrast. The weird part? My skin tone looks more even. Didn’t expect that.

It’s the smartest peptide serum I’ve tested this year. Not because it’s trendy, but because it’s actually formulated like someone read the research.
