Description

Repair. Regenerate. Restore.
The GHK-Cu Copper Peptide Serum is a clinically validated serum powered by one of the most researched peptides in regenerative skincare. Naturally produced by your body, GHK-Cu acts as a cellular repair signal — instructing your skin to rebuild collagen, restore elastin, and perform the way it once did. Over time, your levels drop by 60%. This serum puts them back.
Fragrance-free. Sensitive skin safe. Built for results.
How it works
+
Your skin has a built-in repair system — and GHK-Cu is at the centre of it. It's a copper peptide your body produces naturally to signal skin cells to rebuild and regenerate. Over time, those levels decline and the repair slows down.
This serum replenishes GHK-Cu in its most bioavailable form, reactivating over 4,000 genes responsible for collagen production, barrier repair, and cellular renewal.
No needles. No harsh actives. Just your skin's own biology, restored.

"This is great. I don't rely on make up as much since my face lines are fading and skin is getting tighter. Great serum

My friends think im too critical of myself but over time I started wanting smoother and more even look you i see on other women my age online. I kept my routine simple and added this in, and within about a few weeks my skin felt noticeably softer, even and clearer with little breakouts.

I started noticing my face was beginning to sag a little, especially around my cheeks and jawline. As a mum and wife, you get so caught up in everything else that you forget about yourself a bit. I wanted to feel confident again, not just for me but for my husband too. After using this for a couple of weeks, my skin started to feel firmer and looked more lifted. Now my face looks tighter and more refreshed, and I feel so much better when I look in the mirror. Good Product!

I’ve struggled with under-eye bags for a little while now, especially being a mum with a full time job. I did try a under eye device thing but saw little difference. Started using ghkcu about 6-7 weeks ago and i'm really happy with how it's helped reduce the bag to pretty much nothing.

| How To Use.
A quick guide to seeing the best results -
1. Cleanse
+
Start with freshly cleansed skin. Clean skin ensures maximum absorption of the peptide complex.
2. Apply
+
Dispense 2–3 drops onto your fingertips or directly on face and gently rub onto your face and neck. The lightweight formula absorbs instantly without pilling.
For deeper absorption, use our Derma Stamp before applying — it creates micro-channels in the skin that drive the serum further in, amplifying your results.
3. Moisturise
+
Follow with your preferred moisturiser to seal the serum's active ingredients into the skin and lock in hydration.
For better results, we recommend pairing with our GHK-Cu Rejuvenation Cream — This keeps the skin deeply hydrated while the GHK-Cu in the formula continues supporting collagen production and cellular repair, keeping your entire routine working toward the same result.
4. Layer
+
Once the gel has fully massaged in & absorbed, RINSE the applied area & follow with your favourite body moisturiser to seal everything in and keep skin hydrated throughout the day.
5. Consistent
+
Use daily or every send day, either first thing in the morning or right before bed.
Clinical improvements build over weeks of consistent use. Most users notice visible changes in firmness and texture within 4–8 weeks.

Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
How long until I see results?
+
Most users notice improvements in texture and hydration within 2–4 weeks. Deeper changes — firmness, collagen rebuilding, wrinkle reduction — develop over 8–12 weeks of consistent daily use. This is biology, not a quick fix.
Can I use this on sensitive skin?
+
Yes. Unlike most active ingredients, GHK-Cu is non-irritating and anti-inflammatory. It's one of the few serums that delivers powerful results without compromising your skin barrier.
Do I need to refrigerate it?
+
Refrigeration isn't required, but we recommend it. Keeping the serum cool helps preserve peptide stability and potency, ensuring every drop performs at its best.
Is this safe to use during pregnancy or while breastfeeding?
+
We recommend consulting your doctor before use during pregnancy or breastfeeding. While GHK-Cu is a naturally occurring peptide, we always advise speaking with your healthcare provider before introducing any new skincare actives during this time.
Can MEN use this serum?
+
Absolutely. GHK-Cu works at a cellular level — it doesn't discriminate. Men dealing with loss of firmness, rough texture, or slow skin recovery will see the same results. The lightweight formula sits comfortably under moisturiser or SPF without any residue.
