FREQUENTLY ASKED

Which peptides are studied for the skin barrier?

GHK-Cu leads barrier research, studied for repairing the dermal matrix and supporting the structures that keep moisture in and irritants out. KPV is of research interest for the inflammatory, reactive component of a compromised barrier. Supplied for research purposes only.

How does barrier research differ from dry-skin research?

Barrier research centres on the skin’s protective function — sensitivity, redness and reactivity from a damaged barrier — while dry-skin research focuses on hydration and moisture loss. A weakened barrier often underlies both. Evidence is preliminary.

Are these CoA-certified?

Yes — every batch is HPLC-verified with a Certificate of Analysis, in discreet tracked packaging nationwide.
