LOOP PEPTIDE BEAUTY
Introducing the Loop GHK-Cu Glow Set
Powered by 2% pure GHK-Cu—formulated to support collagen synthesis, cellular repair, and skin that appears firmer, clearer, and more resilient over time.
OUR MISSION
We set out to harness the power of the beauty peptide and formulate it at levels that matter. 2% pure GHK-Cu. Two products designed to work together. Clinical grade, at home.
Working with leading peptide experts, dermatologists, and skincare chemists, we spent months testing, refining, and perfecting. Every texture, every concentration, every detail — formulated with intention and held to the highest standards.
Prep. Signal. Renew.
01 — GHK-Cu Signal Serum
The foundation of the system. 2% pure GHK-Cu in a lightweight, fast-absorbing serum that preps skin to receive what comes next. Supported by Sodium Hyaluronate for deep hydration, Panthenol to soothe, and a multi-peptide complex including Argireline and Matrixyl for visible smoothing.
Lock in. Restore. Strengthen.
02 — GHK-Cu Renewal Cream
Rich but never heavy. 2% GHK-Cu in a barrier-supporting base designed to seal in your serum and support overnight recovery. Formulated with Ceramide NP to reinforce skin's natural barrier, Panthenol for lasting hydration, and Vitamin E for antioxidant protection.
the science
Glycyl-L-Histidyl-L-Lysine Copper (aka GHK-Cu)
GHK-Cu is a copper tripeptide your body already makes — abundant when you're young, and quietly declining as you age (because of course it does).
It works by activating fibroblasts — the cells responsible for producing collagen, elastin, and glycosaminoglycans, the key building blocks of healthy, resilient skin. It also supports antioxidant activity, helping reduce oxidative stress while improving micro-circulation.
But here's what makes it different: GHK-Cu functions as a cellular signaling molecule. It doesn't just add something to your skin — it communicates repair instructions at the cellular level. In scientific literature, GHK-Cu is widely studied for its role in tissue remodeling, collagen synthesis, inflammation modulation, and aesthetic regeneration pathways.
From a biological standpoint, this creates an environment that favors repair, renewal, and structural integrity.
