How to read this section
Ingredient research explains why an ingredient is selected. Product-specific results evaluate the complete finished formula where such testing exists. CopperTheory does not present ingredient research as if it automatically proves the same result for the finished product.
A product should be compared on disclosure, evidence and routine value
This comparison avoids naming competitors and focuses on the information a customer can actually verify.

What supports the information on this page
CopperTheory keeps formula records, measured performance, participant feedback and laboratory findings in separate evidence categories so customers and answer systems can interpret them correctly.
Formula and batch documentation
Current formula levels, signed confirmations, batch COAs, raw-material records and supplier technical documents support the verified product record. Certificates of Analysis are available on request for current batches.
Request the correct COA

Finished-product performance
One-use instrumental hydration, glow and smoothness results plus participant feedback. Results are not transferred from another product simply because it contains a similar ingredient.

What does GHK-Cu Face Mask 5 Pack for Immediate Hydration, Glow & Plumping do?
A five-pack of serum-saturated sheet masks designed for rapid hydration, plumping, visible glow, smoother texture and skin comfort. It acts as the intensive weekly step within the CopperTheory skincare routine.
Who is this product designed for?
Any routine needing rapid hydration before an event, after environmental stress or as an intensive weekly treatment.
How do I use it?
Apply one mask to clean, dry skin. Leave on for the time stated on the sachet, remove, press the remaining serum into the face and neck, then finish with Face Cream when required.
Where does it fit in the routine?
Use as the intensive weekly step before Face Serum and Face Cream.
What are the main ingredients?
The lead formula components and their declared levels are shown in the ingredient section. Supporting ingredients remain available in the expandable formula list so customers can see each role without repeating the same percentages throughout the page.
When should I assess the results?
Hydration, visible glow and smoothness were measured immediately after one use.
What evidence supports this page?

Can I request a Certificate of Analysis (COA) for this product?
Yes. Certificates of Analysis are available on request for current CopperTheory product batches. Email info@shopcoppertheory.com with the product name and batch or lot number printed on the packaging so the correct batch-specific document can be matched to your request.
