2 studies found

Research context

GHK-Cu in experimental rat wounds

Rats in several experimental groups; no human participants

What did they want to find out?

Did experimental wound tissue change?

What did researchers observe?

Treated wound chambers accumulated more tissue matrix, including collagen.

What does this mean for you?

More collagen in a rat chamber does not demonstrate better skin in a person.

What we still do not know

A rat-wound measurement does not demonstrate a human cosmetic benefit; GLOW was not tested.

Research context

Topical GHK-Cu after laser resurfacing

13 patients completed the trial after CO2 laser treatment

What did they want to find out?

Did adding GHK-Cu improve skin after laser treatment?

What did researchers observe?

No clear between-group difference was detected on objective measures; satisfaction was higher with the GHK-Cu product.

What does this mean for you?

Greater satisfaction and better objective measurements are different outcomes.

What we still do not know

Small sample and abstract-only access. Neither injections nor GLOW were tested.
