GHK-Cu 2% Peptide Gel Serum – Paraiba Edition
Ultra-High Strength Copper Peptide Dermal Regeneration Gel.
 
The new GHK-Cu 2% Peptide Gel Serum – Paraiba Edition is a high-performance copper peptide formulation designed to support skin regeneration, dermal recovery and extracellular matrix renewal.
 
Formulated with 2% w/v GHK-Cu, this advanced gel delivers one of the highest strength copper peptide concentrations available in a cosmetic formulation.
 
The Paraiba Edition range is named for the distinctive deep blue copper complex, which, in gel form, interacts beautifully with light to produce subtle shifts in tone reminiscent of the rare Paraiba tourmaline gemstone.
 
This refined gel format provides controlled skin contact and enhanced peptide stability, allowing the copper tripeptide complex to remain active in the dermis and subcutaneous layers of your skin for extended periods. The gel melts beautifully into the skin with no "tack", or residue detectable on the skins surface due to the mixed molecular weight of the gel formulation.  
 
The Biology of Copper Peptides
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper Complex) is a naturally occurring signalling peptide found in human plasma and tissues. It plays an important role in cellular repair pathways, collagen synthesis and tissue remodelling.
 
Research has shown copper peptides may support:
• stimulation of collagen and elastin production
• improved skin elasticity and firmness
• dermal repair signalling and tissue regeneration
• reduction of visible fine lines and skin damage
• antioxidant and anti-inflammatory activity
• restoration of healthy extracellular matrix structure
 
Delivering 2% GHK-Cu creates a powerful signalling environment designed to support the skin’s natural regenerative mechanisms.
 
Advanced Hydrating Gel Matrix
The Paraiba Edition Gel Serum uses a carefully balanced base designed to hydrate, stabilise and distribute the copper peptide complex efficiently.
 
Aloe Vera
Provides soothing botanical hydration while supporting skin comfort and barrier function.
Sodium Hyaluronate
A powerful moisture-binding molecule that improves skin hydration and supports dermal structure.
Vegetable Glycerin
Acts as a humectant, drawing water into the skin to maintain optimal hydration and improve peptide diffusion.
Carboxymethylcellulose
Forms the gel structure, allowing the peptide complex to remain evenly distributed and maintain consistent skin contact.
Alcohol Denat.
Enhances absorption and ensures the formulation spreads smoothly across the skin.
Ethylhexylglycerin & Phenoxyethanol
Provide a balanced preservation system ensuring long-term product stability.
 
Why a Gel Format?
While the Paraiba Edition mist provides rapid peptide distribution, the gel formulation offers prolonged skin contact, making it ideal for targeted dermal treatment areas such as the periorbital skin under the eyes.
 
Benefits of the gel delivery system include:
• extended peptide contact time
• controlled dermal absorption
• targeted application to specific areas
• enhanced hydration and skin conditionin
 
Supplied in coated Aluminium tins in 2 sizes:
 
15gm Mini Tin
60gm Full Size Tin
 
Paraiba Edition
The Paraiba Edition represents the highest strength copper peptide formulations within the ROK skincare range.
 
The distinctive blue colour arises from the copper-peptide complex itself, not artificial dyes — a visual indicator of the active compound responsible for the product’s regenerative signalling properties.
