Observations in research suggest that significant changes in skin density, texture, and scar appearance can take 8-12 weeks or longer, consistent with the natural skin remodeling cycle
The copper uglies happen because GHK-Cu actively signals skin regeneration, which can temporarily surface underlying issues like clogged pores, low-grade inflammation, or trapped sebum
However, caution should be taken when extrapolating these results to the clinic
This is why its effects compound over time and why the before and after results tend to be broader and deeper than single-mechanism peptides
