Blue Copper Peptide Serum

HYDRATING PEPTIDE SERUM FOR DEHYDRATED, TIRED-LOOKING SKIN AND FINE LINES FROM DRYNESS

£34

PROUD TO BE

CONSULTATION-LED

Skincare is recommended after an in-clinic assessment of your skin, not in place of one.

PROFESSIONAL POSITIONING

Formulated for professional use alongside in-clinic treatments, with realistic expectations set.

EVIDENCE-LED ACTIVES

Every key active is chosen on published ingredient research, referenced on its product page.

An advanced hydrating peptide serum combining Copper Tripeptide-1 with Oligopeptide-1, beta-glucan, polyglutamic acid, Centella asiatica, trehalose and sodium hyaluronate. Designed to support hydrated, smoother, firmer and more resilient-looking skin.

Key Active Ingredients

Copper Tripeptide-1 (GHK-Cu)

A naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) that binds copper to form the GHK-Cu complex.

Supports smoother, firmer-looking skin and helps skin feel more resilient and comfortable.

Beta-Glucan

A polysaccharide used in skincare as a film-forming humectant and biological response modifier.

Helps form a moisture-supporting film on the skin and supports a comfortable, conditioned feel.

Polyglutamic Acid

A high-molecular-weight polymer of glutamic acid used as a humectant and film-former.

Helps hold moisture at the skin surface for a smoother, plumper feel.

Centella asiatica

A botanical extract with a long history of use in supportive skincare.

Helps calm and condition the skin; associated with antioxidant activity.

Trehalose & Sodium Hyaluronate

Trehalose is a naturally occurring disaccharide; sodium hyaluronate is the salt form of hyaluronic acid.

Helps retain moisture and support formulation stability and skin comfort.

Oligopeptide-1

A short peptide used in cosmetic formulations.

Supports a conditioned, smooth feel.

06 — THE EVIDENCE

THE EVIDENCE, NOT JUST THE CLAIM.

Skincare marketing can make almost anything sound impressive. We would rather show you the research.

Our Evidence Library connects key active ingredients with published research so you can understand what has been studied, how it was studied, and how relevant that evidence is to the product you're using. Research on an ingredient does not automatically mean the finished Beyond Skin formulation has been clinically tested. When the evidence applies to an ingredient rather than our finished formula, we tell you. No blurred lines. No invented percentages. Just better-informed skincare.

How to Use

01Apply to clean, dry skin morning and/or evening.
02Dispense a small amount and smooth over the face and neck.
03Follow with moisturiser to seal in hydration.
04Always use a broad-spectrum SPF during the day.

SCIENCE & CLINICAL REFERENCES

The research behind the actives in this product

These references relate to the individual active ingredients, as studied in published research. Unless an entry says otherwise, they are not clinical trials of the finished Beyond Skin formulation — ingredient-level evidence does not mean the finished product has been clinically tested.

01
INGREDIENT
Copper Tripeptide-1 (GHK-Cu)
AUTHOR / STUDY
Pickart et al. — The human tri-peptide GHK and tissue remodeling.
JOURNAL
Journal of Biomaterials Science, Polymer Edition
YEAR
2008
EVIDENCE TYPE
MECHANISTIC / REVIEW EVIDENCE
WHAT WAS STUDIED
Much of the supporting literature is mechanistic, laboratory and review evidence rather than controlled trials of a finished cosmetic serum. It should not be read as clinical proof that this serum increases collagen.
RELEVANCE TO THIS INGREDIENT
For its association with extracellular matrix biology, fibroblast activity and regenerative signalling.
Evidence relates to the peptide in research settings, not to the finished Beyond Skin serum. No product-specific clinical testing is implied.

02
INGREDIENT
Beta-Glucan
AUTHOR / STUDY
Pillai et al. — Anti-wrinkle therapy with beta-glucan (27 subjects, 8 weeks). See review: Exploring the Properties and Application Potential of β-Glucan in Skin Care.
JOURNAL
Food Science & Nutrition
YEAR
2025
EVIDENCE TYPE
CONTROLLED CLINICAL TRIAL
WHAT WAS STUDIED
A clinical study in 27 subjects reported reductions in the appearance of wrinkle height and depth after eight weeks of topical oat beta-glucan. This is ingredient/formulation evidence, not testing of this serum.
RELEVANCE TO THIS INGREDIENT
For hydration, soothing and barrier support.
Reported outcomes relate to a specific beta-glucan formulation and concentration. Results cannot be generalised to every beta-glucan product.

INGREDIENT
Polyglutamic Acid
AUTHOR / STUDY

JOURNAL
International Journal of Molecular Sciences
YEAR
2025
EVIDENCE TYPE
MECHANISTIC / REVIEW EVIDENCE
WHAT WAS STUDIED
Evidence is primarily mechanistic and formulation-based, focused on film-forming hydration.
RELEVANCE TO THIS INGREDIENT
To support surface hydration and a moisture-retaining film.
Effects depend on molecular weight and concentration in the specific formulation.

INGREDIENT
Centella asiatica
AUTHOR / STUDY

JOURNAL

EVIDENCE TYPE
REVIEW
WHAT WAS STUDIED
Evidence is largely mechanistic and review-based; it does not mean this serum heals wounds.
RELEVANCE TO THIS INGREDIENT
For soothing, skin conditioning and support for skin recovery.
Do not interpret soothing support as wound healing or medical treatment.

INGREDIENT
Trehalose & Sodium Hyaluronate
AUTHOR / STUDY
Humectant hydration — mechanistic literature.
JOURNAL
Dermatologic Therapy
YEAR
2022
EVIDENCE TYPE
MECHANISTIC / REVIEW EVIDENCE
WHAT WAS STUDIED
Mechanistic humectant evidence; no claim that sodium hyaluronate 'penetrates deeper' is made without known molecular weight data.
RELEVANCE TO THIS INGREDIENT
For humectant hydration and skin conditioning.
Hydration is surface-level; penetration depends on molecular weight, which is not specified here.

INGREDIENT
Oligopeptide-1
AUTHOR / STUDY
Oligopeptide-1 — identity verification pending.
EVIDENCE TYPE
IN-VITRO
WHAT WAS STUDIED
Raw-material identity must be verified before any specific biological claim is made.
RELEVANCE TO THIS INGREDIENT
As a skin-conditioning peptide.
REFERENCE PENDING RAW-MATERIAL IDENTITY VERIFICATION

We separate ingredient-level evidence from finished-product clinical evidence. Where research investigates an ingredient, we say so. Where it investigates a finished formulation, we say that too. We do not present one as the other.
