They act as a natural booster by stimulating the production of collagen and elastin, the key proteins that provide skin support. Their role is to preserve your face’s youthful appearance by helping to prevent the first signs of wrinkles and reducing the appearance of existing wrinkles. They also help maintain optimal hydration throughout the day.

BIOCHEMICAL COMPOSITION
Copper Peptides are a tripeptide complex composed of amino acids and copper ions. Copper Peptides occur naturally in the body; they play a role in the human body’s metabolism and offer numerous benefits: they stimulate the production of collagen and elastin, help protect skin cells from damage caused by free radicals, maintain hydration and repair the skin, notably by reducing inflammatory factors.
Copper Peptides: What Effect Does It Have on the Skin?
Copper Peptides, and more specifically the GHK-Cu complex, are capable of transporting essential trace elements, such as copper, to skin cells. Naturally present in human plasma, this tripeptide acts as an early repair signal during skin discomfort, being released following the breakdown of collagen.
Its main action is to stimulate fibroblasts—the key cells responsible for the skin’s youthfulness—to increase the synthesis of major structural proteins such as collagen and elastin.
In addition to boosting production, Copper Peptides play a vital regulatory role in the enzymes responsible for the breakdown of the skin matrix, thereby helping to maintain firmer skin and prevent the accumulation of damaged proteins.
They also aid the synthesis of moisturising molecules such as glycosaminoglycans and decorin, a protein that organises collagen fibres to ensure their uniformity and cohesion.
Copper Peptides: Scientifically Proven Efficiency
The effectiveness of Copper Peptides is backed by several scientific studies.*
The in vivo results highlight a visible improvement in the quality of the skin. In particular, a measurable increase in skin density and thickness has been observed, alongside a reduction in the visibility of fine lines and the depth of wrinkles. A comparative clinical study has also highlighted that this complex reduces wrinkle volume by 31.6% compared with other recognised peptides on the market.
Furthermore, in vitro studies carried out on cell cultures demonstrate the potency of this active ingredient at the heart of the epidermis. Biological tests reveal that Copper Peptides act as powerful boosters, capable of stimulating the synthesis of collagen and elastin. This laboratory research also confirms a positive effect on the proliferation of keratinocytes, which play a vital role in maintaining a firm skin structure and a refined skin texture.

Skin tolerance
A Note from Adeline Nalin, Head Pharmacist and Toxicologist at Aroma-Zone
“Copper Peptides are molecules that combine amino acids and copper ions. They are widely used in skincare products and are generally very well tolerated, even by those with sensitive skin.”
Adeline Nalin - Head Pharmacist and Toxicologist
A Safe Ingredient for your Health
A Note from Our Aroma-Zone Toxicologist
“Copper Peptides are considered safe for use in cosmetic products, provided they are used within the recommended concentration limits.”
Adeline Nalin - Head Pharmacist and Toxicologist
A Note from the Dermatologist
“Copper Peptides are biotechnology-derived active ingredients that combine short peptides with copper ions to optimise their bioavailability. This combination enables targeted action at the skin level, particularly on the mechanisms involved in skin firmness and quality.
They are particularly beneficial in skincare routines aimed at improving elasticity and supporting the skin’s structure, whilst also providing protection against oxidative stress.
Tip: Use regularly, avoiding direct combination with powerful exfoliants or sensitising active ingredients to preserve the skin’s balance.”
Dr Agathe Aoun – Dermatologist
Formulation Focus with the Aroma-Zone R&D Laboratory
Copper Peptides are active ingredients with a small molecular size, which allows them to penetrate the superficial layers of the skin more easily. This makes them valuable ingredients for targeting the visible signs of ageing. In particular, they work by stimulating the synthesis of collagen and elastin, two components essential for skin firmness and elasticity. The skin is therefore visibly smoother, with reduced wrinkles and fine lines.
For Which Skin Types?
Copper Peptides are versatile and suitable for all skin types, including sensitive skin seeking a gentle yet effective solution. It is particularly recommended for mature skin showing signs of sagging or established wrinkles. However, it is equally suitable for young adults wishing to adopt a skincare routine to prevent skin ageing and smooth their skin texture.
Which Concerns Does This Address?
This active ingredient is ideal for those experiencing a loss of firmness and elasticity, two major age-related concerns.
It specifically addresses the issues of expression lines, particularly on the forehead and around the eyes, as well as deeper wrinkles on the face and neck.
What Copper Peptides Do for the Skin
Tissue firming: improves skin elasticity and restores tone to the face
Regeneration and structural support: promotes the production of elastin and collagen
Wrinkle correction: helps reduce the appearance of even deep wrinkles and smooths fine lines for a refined skin texture that feels softer to the touch
Cellular shield: protects skin cells from external aggressors
Radiant complexion: helps to clarify the skin by reducing the appearance of dark spots and imperfections
Skin Strengthening: supports the integrity of the skin’s protective barrier.
