Paraiba Reserve™ — GHK-Cu 2% Multi-Peptide Serum
The Ultimate Daily Copper Peptide Serum by ROK Medical
 
Paraiba Reserve™ — GHK-Cu 2% Multi-Peptide Serum is ROK Medical’s most advanced copper peptide skincare formula: a high-strength 2% GHK-Cu serum built into a clean, fragrance-free, multi-peptide hydration matrix for daily use across the face, neck and décolletage.
 
This is our most complete expression of what a premium topical GHK-Cu copper peptide serum can be. Rather than creating another single-active copper peptide product, Paraiba Reserve™ combines an exceptional 2% GHK-Cu concentration with a supporting system of multi-weight hyaluronic acid, cosmetic peptides, ectoin, panthenol, beta-glucan, silk protein, zinc PCA and betaine.
 
The result is a deeply considered, high-performance daily serum designed for customers who want more than hydration, more than a standard peptide serum, and more than a basic blue copper peptide formula.
 
Paraiba Reserve™ is created to deliver a complete cosmetic skin-conditioning experience: visible hydration, improved skin smoothness, a more refined skin feel, enhanced comfort, and a firmer, healthier-looking complexion.
 
A 2% GHK-Cu Serum Designed to Stand Apart
At the centre of Paraiba Reserve™ is 2% GHK-Cu, also known as Copper Tripeptide-1. 
 
Many copper peptide serums on the market use lower concentrations, simpler bases, or formulas built primarily around water, glycerine and a small amount of peptide. Paraiba Reserve™ has been developed differently. The 2% GHK-Cu is supported by a sophisticated hydration and peptide-support matrix designed to make the product feel complete, luxurious and suitable as a true daily serum step.
 
Why Paraiba Reserve™ Is Different
Paraiba Reserve™ was created for customers who want the strongest and most complete expression of the Paraiba range. It takes the signature blue to purple colour of our Paraiba 2% GHK-Cu products and elevates it into a more luxurious, multi-functional daily serum.
 
The formula includes:
2% GHK-Cu / Copper Tripeptide-1 for premium copper peptide skincare positioning.
5% Multi-Weight Hyaluronic Acid Complex for multi-level hydration and a visibly plumper skin appearance.
SNAP-8 / Acetyl Octapeptide-3 to support the appearance of smoother, more relaxed-looking skin.
Palmitoyl Tripeptide-1 to complement the peptide profile and support the look of firmer, more conditioned skin.
Ectoin to help support skin comfort and environmental resilience.
Panthenol to condition, soothe and support a healthy-looking skin barrier.
Hydrolysed Silk Protein for a smooth, soft, elegant skin finish.
Zinc PCA to support a balanced, refined skin feel.
Beta-Glucan to cushion, calm and hydrate the skin.
Betaine to improve moisturisation, comfort and overall skin feel.
 
The formula is fragrance-free, colourant-free and minimalist in structure, allowing the natural blue/purple colour of GHK-Cu to remain the visual signature of the product.
 
Hero Active: 2% GHK-Cu / Copper Tripeptide-1
GHK-Cu is the defining active in Paraiba Reserve™. It is a copper-bound tripeptide used in advanced cosmetic skincare for its association with skin conditioning, visible age-support and improved skin appearance.
 
For customers searching for a 2% GHK-Cu serum, copper peptide serum, Copper Tripeptide-1 skincare, or a peptide serum for daily skin support, Paraiba Reserve™ has been formulated to be the ultimate expression of what is scientifically possible with topical Copper peptides.
 
5% Multi-Weight Hyaluronic Acid Complex
Hydration is essential to how skin looks and feels. Paraiba Reserve™ uses a 5% Multi-Weight Hyaluronic Acid Complex to provide a more complete hydration profile than a standard single-weight hyaluronic acid serum.
Different molecular weights of hyaluronic acid can contribute to different aspects of cosmetic hydration and skin feel. Higher-weight hyaluronic acid helps create a smooth hydrated film on the skin surface, while lower-weight forms support a more cushioned, plump and refreshed appearance.
 
This makes Paraiba Reserve™ more than a copper peptide serum. It also functions as a premium daily hyaluronic acid peptide serum, helping skin look fresher, smoother and more hydrated after application.
 
Paraiba Reserve™ is clean and elegant: No unnecessary perfume. No decorative colour. No overcomplicated filler story or "active dusting", found in many other products.
 
Paraiba Reserve™ is available exclusively in a 100ml amber glass bottle with a compact white lotion pump and clear protective cap.
 
How to Use Paraiba Reserve™
Apply Paraiba Reserve™ after cleansing to clean, dry skin.
Use 1–2 pumps across the face and neck. Apply once daily to begin, then increase to twice daily if desired and well tolerated.
Paraiba Reserve™ can be used as your dedicated copper peptide serum step. Due to its high level of hyaluronic acid, glycerin, panthenol, betaine and other humectants, many users may find that they do not require a separate moisturiser.
Drier skin types may still choose to follow with a moisturiser or cream.
 
For best results, use consistently as part of your daily skincare routine.
