6 Reasons Women 45+ Are Adding This Blue Peptide Cream to Their Skincare Routine
You didn’t fail your skincare routine. It was missing the one peptide your skin makes less of every year.

The premium serums. The regular facials. The beautiful jars that promised so much.
None of it was wasted. But GHK-Cu is a copper peptide your body makes on its own, and those levels tend to fall as skin ages. That is the gap. Here are six reasons women 45+ are closing it.
The collagen research gives you a reason to look closer.
Collagen is part of what gives skin its structure. In a small, one-month pilot study, 70% of participants treated with a copper-peptide cream showed increased procollagen synthesis—an early step in collagen production.‡

Researchers measured changes in wrinkles.
In an eight-week study involving 40 women aged 40–65, a specially formulated GHK-Cu serum delivered 55.8% greater reduction in wrinkle volume versus control serum.†
That study tested a different product using a specialized delivery system, not InfiniWell’s finished cream.

Wrinkle depth improved in that study, too.
The same GHK-Cu serum showed 32.8% greater reduction in wrinkle depth versus control serum after eight weeks.†
Together, these findings help explain the interest in copper peptides for smoother-looking skin.

† Badenhorst et al., Journal of Aging Science (2016; 4:166). Eight-week study involving 40 women aged 40–65, using a GHK-Cu serum with a lipid-based nano-carrier twice daily. Reported wrinkle-volume and wrinkle-depth comparisons are versus control serum, not absolute reductions from baseline. This was not a study of InfiniWell GHK-Cu cream.
‡ Abdulghani et al. (1998; pilot study, n=20 overall, one month), as summarized in this published research review. The 70% figure refers to the proportion of copper-peptide-treated participants showing increased procollagen synthesis—not a 70% increase in collagen.
