LESS TEXTURE. MORE STRUCTURE. SKIN THAT KEEPS UP.
A high-strength GHK-Cu copper peptide serum built to support firmness, repair, and natural collagen production. Your jawline is genetics. Your skin is a choice.
The Science Behind GHK-Cu
GHK-Cu isn't a trend. It's a peptide your body already produces — studied since 1973, with a deep base of published research documenting what it does at the cellular level: it signals the cells responsible for collagen and elastin production to increase output. More collagen means denser, firmer-feeling skin. More elastin means skin that stays tight instead of going soft. Natural levels decline as you age; topical application is how you put it back to work. Absorbs fast. No residue. Builds the longer you use it.
What it does
- Boosts collagen — visibly firms skin and supports elasticity
- Accelerates repair — helps skin recover from blemish marks and environmental damage
- Reduces redness — calms and evens tone
- Deep hydration — sodium hyaluronate locks in moisture immediately
- Smooths texture — refines the skin surface for an even finish
- Enhances radiance — restores a healthy, awake look
How to use
1. Cleanse — start with clean, dry skin. 2. Apply — 3–4 drops to face and neck. 3. Press in — gently until absorbed, about 60 seconds. 4. Follow — moisturiser, plus SPF in the morning. Consistency beats intensity: results build over weeks of daily use.
FAQ
Does topical GHK-Cu actually work? It's one of the most-studied peptides in skincare, with published research on collagen support, firmness, and skin repair. It's a repair peptide, not a filter — give it weeks, not days.
How long until I see a difference? Most users notice hydration and glow in 1–2 weeks; firmness and texture improvements build over 4–12 weeks of daily use.
Can I use it with retinol or vitamin C? Pairs well with retinol (alternate nights if sensitive). Avoid layering directly with strong vitamin C — use them at opposite ends of the day.
Will it break me out? The formula is lightweight, fragrance-free, and non-occlusive. The blue colour is the copper itself — no dyes.
Why 3 or 6 bottles instead of one? Peptide results compound with consistent use. One bottle is roughly a 2-month supply; the 3- and 6-bottle protocols cover the window where the visible changes happen — at a lower cost per bottle.

Any other questions?
GHK-Cu is one of the most studied peptides in skincare — over 70 published studies covering collagen production, skin elasticity, wound repair, and cellular regeneration.
It's not a new ingredient and it's not a trend. It was first identified in 1973 and has decades of research behind it.
The reason most people don't see results from copper peptide products isn't the ingredient - it's the dose. The majority of brands formulate at 0.5-1% to cut costs. At that concentration, you're unlikely to notice much. Our formula uses 2% - the maximum effective topical concentration - which is why our customers see results that other serums haven't delivered.
Yes - but timing matters.
With retinol: Don't apply them at the same time. GHK-Cu and retinol can counteract each other when layered simultaneously. The protocol that works: GHK-Cu in the morning, retinol at night. You get the benefits of both without interference.
With vitamin C: Apply vitamin C first, let it fully absorb, then apply GHK-Cu on top.
Both are morning-friendly actives and they don't conflict when applied this way.
With SPF and moisturizer: No issues. Apply GHK-Cu first, let it absorb, then layer your moisturizer and SPF over it as normal.
If you're already using retinol and want to add this, the 6-month supply is the right call
- you're building a long-term stack, not testing a single product.
Other brand formula's use 0.25-1% GHK-Cu. Ours uses 2%. That's double the active concentration.
Beyond that: our formula pairs the peptide with a 1.5% sodium hyaluronate complex, which means you're getting deep hydration alongside the collagen-signaling benefits
- not just a standalone peptide in a basic base. Other companies don't include this.
We also back every order with a 90-day money-back guarantee. They don't offer anything close to that. If you've tried theirs and felt underwhelmed, concentration is almost certainly why.
No. The formula is non-comedogenic, oil-free, and fragrance-free. It won't clog pores and it doesn't contain any of the common irritants - no parabens, no sulfates, no synthetic dyes, no artificial fragrance.
It's a lightweight water-based serum. It absorbs fully within about 60 seconds and leaves no residue. The vast majority of customers - including those with sensitive or acne-prone skin - tolerate it without any issues.
If you're extremely sensitive, we recommend a 24-hour patch test on your inner arm before full application. But breakouts from this formula are not something we hear about.
Here's an honest timeline based on what our customers consistently report:
Week 1: Less morning puffiness. Skin looks slightly cleaner and more refreshed. The hyaluronic complex is working immediately - you'll notice the hydration before the peptide effects fully kick in.
Weeks 3-4: Smoother texture, more even tone. This is when people start asking what you've changed. You'll notice it in photos and in normal lighting.
Weeks 8-12: Firmer, more defined-looking skin. This is the compound result of consistent daily use - collagen signaling takes time to show up structurally, but when it does, the difference is noticeable.
Individual results vary. But if you stop after two weeks because you haven't seen a dramatic change yet, you've quit before the best part.
Because one bottle covers about 30 days, and 30 days isn't long enough to see the full result.
The timeline is real: puffiness and hydration improve in the first week or two. Texture and tone improve around weeks 3-4. The structural changes - firmer, more defined-looking skin - show up at weeks 8-12. That's the result people are actually after, and it requires consistent daily use to get there.
One bottle gets you started. Three bottles gets you to the point where the results are undeniable. Six bottles keeps you there at the lowest cost per bottle we offer - $0.48 per day - so you're not paying full price every time you re-order mid-progress.
Most people who start with one bottle re-order anyway. The bundle just means you never run out, you never break the streak, and you pay less for it.
