GHK-Cu Face Serum 1%, 99.6% Verified Copper Peptide Purity

300mg of GHK-Cu copper peptide in a 30ml bottle at 1% concentration. No weighing, no carrier base to formulate, no mixing. Clean skin, a few drops, done.

1% is a well-established concentration in copper peptide skincare. It gives you a meaningful amount of GHK-Cu in a skin-friendly base, without the guesswork of DIY formulations. Formulated and bottled in the UK with every batch HPLC tested before release.

Why 1% and Not Higher for Facial Use

Higher is not always better on facial skin. 1% GHK-Cu in a well-formulated base sits in the range that cosmetic chemists and skincare researchers use most consistently. It gives the copper peptide enough presence to be functional, while keeping the product comfortable for daily use on delicate facial skin.

The Base Formula

The base matters as much as the active. This serum uses sodium hyaluronate for hydration, aloe vera for soothing, and malachite extract as a natural copper mineral source to complement the peptide.

Lightweight blue gel. Absorbs quickly. Sits well under moisturisers or SPF. No fragrance, no silicones, no parabens, no unnecessary fillers. Suitable for all skin types.

How to Use GHK-Cu Face Serum

• Apply a few drops to clean dry skin, morning or evening
• Pat gently into face, neck and decolletage
• Follow with your usual moisturiser, SPF in the morning
• For enhanced absorption, some users apply after a short 0.5mm dermaroller session
• Consistent daily use works better than occasional application

Copper peptides work over weeks of consistent routine, not days. Patience matters more than perfection.

Commonly Asked Questions

How long does GHK-Cu face serum take to show results?
Most people notice skin feel and hydration changes within 2 to 4 weeks. Visible texture and firmness changes typically appear from 4 to 8 weeks of daily use. Consistency beats frequency.

Can I use GHK-Cu with retinol or Vitamin C?
Yes, but at different times. Apply GHK-Cu in the morning and retinol at night, or alternate days. Avoid layering GHK-Cu directly with L-ascorbic acid in the same application, as copper can affect ascorbic acid stability. Space them apart in your routine.

Is it suitable for sensitive skin?
The base is fragrance-free and gentle. Patch test before full face application if you have reactive skin or known copper allergies.

Why is the serum blue?
The blue colour is the copper peptide itself, not a dye. A natural visual signal that GHK-Cu is present in the formula. Slight fading over months is normal copper oxidation and does not affect quality.

Where is it made?
Formulated and bottled in the UK. Every batch lab tested at a UK laboratory with the COA published on this page.
