Let's talk peptides — the tiny amino acid chains doing the heavy lifting behind half the "glass skin" moments on your feed. If you've been side-eyeing GHK-Cu, SNAP-8 and PDRN in your search history but haven't quite pulled the trigger, here's the no-jargon breakdown, Axio style.
First — what even is a peptide?
Peptides are short chains of amino acids that act like little messengers, telling your skin cells to get back to work: make more collagen, calm down inflammation, repair what the sun and stress have been chipping away at. Your skin makes them naturally when you're young — production just slows down as you age, which is basically the whole plot of skincare after 25.
GHK-Cu — the repair peptide
GHK-Cu (glycyl-histidyl-lysine, paired with copper) is one of the most studied peptides in skin regeneration. It shows up naturally in your body, but levels drop off with age. Applied topically, it's known for firming, supporting collagen and elastin production, and softening the look of fine lines and sun damage over time.
This is the star of our GHK-Cu / SNAP-8 Peptide Serum and our richer GHK-Cu Copper Peptide Cream — think of the serum as your daily driver and the cream as the overnight recovery layer.
SNAP-8 — nature's "relax" button
SNAP-8 is often called a topical alternative to more invasive smoothing treatments. It works by gently limiting the muscle contractions that deepen expression lines, particularly around the forehead and eyes. Less dramatic than a needle, more "well, that's convenient."
You'll find it blended into the GHK-Cu serum above for a two-in-one repair-and-smooth effect, or on its own in our SNAP-8 Hyaluronic Acid Face Serum, layered with hyaluronic acid for hydration that actually sticks around.
PDRN — the regeneration peptide from an unexpected place
PDRN (polydeoxyribonucleotide) is derived from salmon DNA and has become a cult favourite in Korean dermatology clinics for its regenerative, soothing properties. It supports tissue repair and hydration, making it a favourite for anyone dealing with a compromised or reactive barrier, post-treatment skin, or just general "my skin has had a week" energy.
It's the whole point of our PDRN Salmon DNA Serum — lightweight, calming, and a genuinely nice thing to layer under everything else. And for the neck and décolletage, our PDRN Neck Firming Cream brings it into a silky daily cream.
And for the scalp: AHK-Cu
Copper peptides aren't just a face thing. Our AHK-Cu Scalp & Hair Serum brings the same copper-peptide logic to the scalp, for a healthier-looking scalp and fuller-feeling hair.
How to actually layer these
- Cleanse first, obviously.
- Peptide serums go on clean, slightly damp skin — thinnest to thickest.
- PDRN or the SNAP-8 serum in the morning, GHK-Cu serum or cream at night (peptides and direct sun exposure aren't best friends).
- Always finish with SPF during the day. Non-negotiable, we don't make the rules.
- Give it 8–12 weeks before you judge results. Peptides are a slow burn, not a highlighter.
The bottom line
You don't need a ten-step routine to get results — you need the right actives doing the right jobs. GHK-Cu for repair, SNAP-8 for smoothing, PDRN for regeneration. Pick your starting point, or just get the set and let your skin decide which one it reaches for first.
