Is GHK-Cu cream worth it?
GHK-Cu has been studied in skin and wound research. That does not establish that a higher-percentage compounded facial cream produces better cosmetic results than a lower-percentage product.

The cited trial studied a topical GHK-Cu gel as part of care for diabetic neuropathic ulcers. That is a different condition and preparation from a facial cream used for wrinkles or texture. The result should not be presented as a trial of the creams offered here.

Is a stronger percentage automatically better?
No comparison cited here establishes that 4% outperforms 2%, or that either concentration is superior to other skin-care options. Concentration alone does not answer questions about the finished formula, tolerability or visible results.
Make the comparison useful
Choose the skin concern first. Ask which evidence supports the proposed cream for that concern, how it fits the rest of your routine and when to assess the result. Compare a full course and tolerability, not just a number on the label.
