Frequently asked questions
How does PeptideClear pick the top GHK-Cu serums?
We rank UK-stocked GHK-Cu serums on six signals: INCI position of GHK-Cu (top 8 means meaningful, bottom third means trace), declared concentration where the brand publishes one, UK availability (Cult Beauty, LookFantastic, Boots, Space NK, Beauty Pie, Holland and Barrett, Amazon UK), compatible base (no low-pH conflicts in the same step), air-tight or pump packaging (peptides oxidise quickly in jars), and price per effective gram of declared peptide.
What should I look for when buying a GHK-Cu serum in the UK?
GHK-Cu should appear in the top 8 of the INCI list to be meaningful; lower than that and it is trace only. A declared concentration figure (1%, 2%) is stronger evidence than an undisclosed proprietary blend. Pump or air-tight packaging matters because copper peptides oxidise quickly when exposed to air. Avoid layering with low-pH acids in the same step because that breaks the peptide bond. The blue tint visible in some serums is the copper.
Are these brands verified?
We verify UK availability and INCI position before listing. We do not independently lab-test product. Concentration figures are as declared by each brand. Where a brand publishes nothing, we say so and rank on INCI position alone.
Do you take affiliate commissions?
Yes. Some links to retailers and brands are affiliate-tracked at no extra cost to you. Editorial selection and ranking are independent of commercial arrangements. A brand with no affiliate relationship will sit above one that pays us if the editorial criteria put them there. Full disclosure at /how-we-are-funded/.
Are GHK-Cu serums legal in the UK?
Cosmetic GHK-Cu serums are sold legally in the UK as cosmetic products under the Cosmetic Products Enforcement Regulations 2013. They are not classified as medicines. Safety profile at cosmetic concentrations is well established. Patch-test on the inner arm if you have sensitive skin.
