what GHK-Cu is
GHK-Cu is a copper tripeptide: three amino acids (glycine, histidine, lysine) bound to a copper ion. It occurs naturally in human plasma and has been used in cosmetic formulation for decades as a skin-conditioning agent.
In an eye patch, GHK-Cu is suspended in a water-rich gel alongside humectants. The patch holds that gel against the thinnest skin on the face for fifteen minutes — long enough for the ingredients to sit on the skin without evaporating the way a serum does.
why a patch instead of a serum
A serum around the eye evaporates in under a minute. A patch is occlusive: it creates a seal that keeps water in contact with skin, so the under-eye area finishes the wear visibly plumper and smoother-looking.
- Occlusion. Moisture stays on the skin instead of into the air.
- Cooling. A chilled patch makes the area look tighter and calmer immediately.
- Dose control. Each single-use pair carries the same amount of serum every time.
- No mess. Nothing migrates into the eye or under makeup.
who copper peptide eye patches suit
GHK-Cu eye patches are a cosmetic step, not a medical one. They suit anyone whose under-eyes look tired, dehydrated, or puffy in the morning — after short sleep, a salty dinner, a flight, or a long screen day.
pep patch™ is fragrance-free and single-use, which makes it a reasonable choice for reactive skin. As with any new product on thin skin, patch test first.
