Copper Peptide Rejuvenation Serum

$270.00



Cosmetic-Grade | USA Finished | Fragrance-Light Formula




A lightweight copper peptide serum built around GHK-Cu, the copper tripeptide with more published skin research behind it than almost any peptide in cosmetics. Paired with niacinamide, sodium hyaluronate, and panthenol, it absorbs in seconds, leaves no sticky film, and leaves skin looking firmer, smoother, and more resilient with consistent use.

Copper Peptide Rejuvenation Serum

Visibly Firmer-Looking Skin
GHK-Cu is a naturally occurring copper tripeptide that declines in the skin as we age. In cosmetic use, formulations built around it are associated with a firmer, smoother-looking complexion and a reduction in the appearance of fine lines over consistent use. Results are cosmetic and appearance-related.
A Lightweight Finish That Actually Disappears
Most “firming” serums buy their slip with heavy silicones or tacky film-formers. This one is built on a sodium hyaluronate and botanical water base that sinks in fast and leaves nothing behind — no grab, no pilling under sunscreen, no shine.
Barrier Support, Not Barrier Stress
Niacinamide (a well-studied vitamin B3 derivative) and panthenol work on the skin’s surface to support a comfortable, resilient barrier — which is why this serum layers well and suits people whose skin protests at retinol.
Hydration That Holds
Sodium hyaluronate is the low-molecular-weight, more spreadable form of hyaluronic acid. It draws water into the upper layers of the skin, giving immediate plumpness and a bouncier look before the peptide work even begins.
Calming Botanical Base
Aloe, rose water, cucumber, and chamomile extracts round out a base chosen to feel calm on application — no sting, no flush, no fragrance load.

EXPLORE Copper Peptide Rejuvenation Serum

What Is a Copper Peptide Serum?

A copper peptide serum is a leave-on skincare product built around GHK-Cu, a tripeptide (glycyl-L-histidyl-L-lysine) bound to a copper ion. GHK occurs naturally in human plasma and skin, and its concentration declines substantially with age — one of the reasons skin loses its bounce and density over time.
Our Copper Peptide Rejuvenation Serum delivers GHK-Cu in a lightweight aqueous base alongside niacinamide, sodium hyaluronate, and panthenol. Where a single-ingredient serum asks one molecule to do everything, this formula pairs the peptide with humectants and barrier-supporting actives so the skin both looks better immediately and is supported over the weeks the peptide work takes.
It is a cosmetic product. It works on the appearance of your skin. It is not a drug, not an injectable, and not a substitute for one.

Who This Peptide Serum Is For

You’ll get the most out of this if:

  • You’re starting to see loss of firmness— the jawline softening, the cheeks a little less lifted — before you’re seeing deep lines.
  • Retinol doesn’t agree with you.Peeling, redness, that tight raw feeling. Copper peptides are a different mechanism and are generally far better tolerated.
  • You hate the feel of most serums.If you’ve abandoned products because they pilled under SPF or left your face feeling shrink-wrapped, the finish here is the entire point.
  • You want one step, not seven.This does hydration, barrier, and peptide in a single layer.
  • You’re already deep into activesand want something that plays well with the rest of your shelf (see the layering FAQ — vitamin C is the one to time carefully).

This probably isn’t your product if:

  • You’re looking for a needle-free version of an injectable.It isn’t one. Different mechanism, different magnitude, different results.
  • You want overnight results.Hydration shows up day one. The firmness story is a 6–12 week one.
  • You have a copper sensitivity or Wilson’s disease— talk to your doctor first.
  • You’re pregnant or nursing— talk to your doctor first.

Why GHK-Cu Works

  1. The peptide.GHK-Cu is a copper-carrying tripeptide. In cosmetic research it’s studied for its role in supporting the skin’s own renewal processes at the surface. It’s one of the few peptides in skincare with a genuine body of peer-reviewed literature behind it rather than a single supplier-funded study.
  2. The delivery.Peptides are large, water-loving molecules. A greasy occlusive base fights them. The sodium hyaluronate and botanical-water base here is built to carry the peptide into the upper layers of the stratum corneum and then get out of the way — which is also why it feels like nothing.
  3. The support cast.Niacinamide supports the skin barrier and helps with the look of tone and texture. Panthenol softens. Hyaluronate plumps. These aren’t filler ingredients; they’re what make the peptide’s slow work visible while you wait for it.

Copper Peptide Rejuvenation Serum FAQs

What is a copper peptide serum?
A copper peptide serum is a leave-on skincare product formulated around GHK-Cu, a copper-bound tripeptide that occurs naturally in human skin and declines with age. It’s used cosmetically to support a firmer, smoother-looking complexion.
What does GHK-Cu do for skin?
GHK-Cu is used in cosmetics to improve the appearance of firmness, fine lines, and skin texture. It’s among the most-researched peptides in skincare, with published literature stretching back decades.
Is a copper peptide serum a Botox alternative?
No. Botox is a prescription injectable that temporarily reduces muscle movement; a copper peptide serum is a topical cosmetic that works on the surface appearance of the skin. They do different things by different mechanisms, and no serum — ours included — replicates an injectable. Anyone selling you “Botox in a bottle” is selling you a phrase, not a result.
Can you use copper peptides with vitamin C?
Best practice is to separate them — use vitamin C in the morning and your copper peptide serum at night. Direct L-ascorbic acid is a strong reducing agent and can destabilize the copper complex when the two are layered together in the same routine.
Can you use copper peptides with niacinamide?
Yes — in fact, they’re formulated together in this serum. The old warnings about the pairing were based on a misreading of high-heat lab conditions that don’t apply to finished cosmetic formulas.
Can you use copper peptides with retinol?
Generally yes, though not layered wet-on-wet. Many people alternate nights, or apply one, wait ten minutes, then apply the other. If your skin is reactive, alternate.
Copper peptides vs retinol — which is better?
They’re different tools. Retinol has the deeper evidence base for photoaging but is poorly tolerated by many people, causing peeling and irritation. Copper peptides are far gentler and work by a different mechanism, which makes them a strong choice for sensitive skin or for anyone who has tried and abandoned retinol.
How long does it take to see results from a copper peptide serum?
Hydration and plumpness are visible the first day. Texture and tone typically shift around weeks 2–4. Changes in the appearance of firmness generally take 6–12 weeks of consistent nightly use.
Is copper peptide serum safe for sensitive skin?
Copper peptides are generally very well tolerated, and this formula is fragrance-light with a calming botanical base. As with any new product, patch test on the inner forearm for 24 hours first. If you have a known copper sensitivity or Wilson’s disease, speak with your doctor before use.
Should I use it in the morning or at night?
Night is ideal, particularly if you use vitamin C in the morning. If you use it in the AM, always follow with SPF 30+.
Will it feel sticky or pill under makeup?
No. The base was formulated specifically to avoid the tackiness common to peptide serums — it absorbs in seconds and layers cleanly under moisturizer, SPF, and makeup.
How should I store it?
Store in a cool, dark place with the cap sealed. Avoid leaving it in direct sunlight or in a hot car.
