A two-product daily ritual, built around one hero peptide.
The foundation of every Loop routine. One ingredient, two delivery curves, one continuous system — designed to support firmer, denser, more resilient-looking skin.
The serum delivers. The cream holds it there.
GHK-Cu is one of the most-studied copper peptides in dermatology — a tripeptide your skin produces in your twenties and quietly stops making with age. In research and in practice, it's known for signaling repair, supporting collagen, and restoring the look skin loses over time.
2× 2% GHK-Cu Signal Serum · 30 ml · the messenger.
A lightweight, fast-absorbing cobalt-blue serum that delivers clinical-strength copper peptide into the skin — where structural support begins.
2× 2% GHK-Cu Renewal Cream · 30 g · the anchor.
A sustained-release cream that seals the signal, delivers a second daily dose of GHK-Cu, and reinforces the barrier with Ceramide NP, Panthenol, and Vitamin E.
Fine lines & wrinkles. Smoothing the appearance of expression lines and surface texture over time.
Collagen. Activating fibroblasts — the cells responsible for natural collagen production.
Scar healing. Supporting the skin's natural repair process and the look of textured or uneven areas.
Hydration. Reinforcing the barrier to lock in moisture and reduce water loss.
Copper glow. The luminous, dewy finish copper peptides are famous for.

Morning and evening. Every day.
Consistency is what changes skin. Use the kit twice a day for eight weeks — the serum signals, the cream seals.
- Cleanse. Pat skin slightly damp — leave it that way.
- Signal Serum · 1–3 pumps. Press and tap into face, neck, and décolletége.
- Renewal Cream · pea-sized. Smooth on top to lock the signal in.
- AM: finish with SPF 30+. Every morning, no exceptions.
Cleanse first, always. Wash your face before applying the serum and cream so the products absorb cleanly without buildup.
Sensing irritation? Pull back on the cream — switch to once daily or every other day until your skin settles.
GHK-Cu plays well with most of your shelf — with one exception. Copper peptides and vitamin C cancel each other out.
