Copper Peptide Face Serum

PLU Laboratories sells cosmetic products, not FDA-approved drugs, so we cannot make claims about producing collagen or affecting the body's structure or function. However, the NIH research describes GHK-Cu as a copper tripeptide-1 studied for its role in tissue processes and collagen production pathways involving dermal fibroblasts and extracellular matrix remodeling. Our Face Tonic uses these peptide concentrations for cosmetic use to support the appearance of firmer-looking, smoother facial skin.

Yes, but apply them separately. The research studies examined copper peptides and Matrixyl 3000 as focused amino acid complexes, not mixed with hyaluronic acid or vitamin C in the same formulation. Apply our Face Tonic to clean facial skin first, then layer hyaluronic acid serum for hydration or vitamin C serum for antioxidant benefits after the peptides absorb. This maintains the peptide concentrations studied in research while allowing you to use other active ingredients in your routine.

Most peptide serums contain either copper peptides OR other peptides, rarely both. Our Face Tonic combines GHK-Cu copper tripeptide-1 with complete Matrixyl 3000 (Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7), creating a dual-peptide system. The NIH research on copper peptides and studies on Matrixyl 3000 examined these specific amino acid sequences. We also exclude hyaluronic acid, vitamin C, and other actives that dilute peptide concentrations, maintaining the concentrations studied in published literature.

Facial serums and tonics are lightweight, water-based formulations designed for deeper penetration and faster absorption of active ingredients like peptides. Facial creams are emulsions containing oils and emollients designed more for surface hydration and skin barrier occlusion. For peptide delivery, lighter serum formulations may allow better penetration of amino acid sequences like GHK-Cu and Matrixyl 3000 to reach dermal fibroblasts and skin cells. Our Face Tonic uses a serum-style formulation to optimize peptide absorption, allowing you to layer a cream or moisturizer over it if additional hydration is desired.

As a cosmetic product, our Face Tonic cannot make claims about wound healing or repairing damage, as those are medical/drug claims. The NIH literature describes copper peptides as compounds studied in research on tissue remodeling processes and extracellular matrix interactions, but our Face Tonic is designed to support the appearance of facial skin texture, skin elasticity, and firmness through cosmetic application of peptide complexes studied in published research.

GHK-Cu (copper tripeptide-1) consists of three specific amino acids (glycine, histidine, and lysine) bound to copper ions. The NIH research describes this copper peptide as a naturally occurring compound where the copper ions are chelated to the amino acid sequence. This conjugated copper form allows the peptide to work as studied in research on dermal fibroblasts and tissue processes. Our Face Tonic delivers GHK-Cu in this copper-bound form alongside Matrixyl 3000 peptides, creating a comprehensive amino acid delivery system for facial skin appearance.

Our Face Tonic focuses on peptide delivery rather than hydration. The dual-peptide system (GHK-Cu + Matrixyl 3000) is designed to support skin texture appearance, skin elasticity appearance, and firmness rather than providing moisture. If you have dry skin, layer a hyaluronic acid serum or facial cream over Face Tonic after the peptides absorb. This approach maintains peptide efficacy while addressing hydration needs separately. The lightweight serum formulation won't interfere with subsequent hydrating products.

Yes. Apply our Face Tonic to clean facial skin first, before any other active ingredients. The dual-peptide serum (GHK-Cu + Matrixyl 3000) absorbs quickly, allowing you to layer vitamin C, hyaluronic acid, ceramide complexes, or other actives afterward. This layering approach maintains the peptide concentrations studied in research while allowing you to use complementary ingredients. Wait a few moments for the peptides to absorb before applying subsequent products.

The NIH research describes GHK-Cu as a copper peptide studied for its role in extracellular matrix processes involving dermal fibroblasts and skin cells. Research on Matrixyl 3000 examined matrikine signaling peptides for facial skin appearance. As a cosmetic product, our Face Tonic supports the appearance of skin elasticity, texture, and firmness through these amino acid pathways studied in published literature. With consistent use, facial skin appears firmer, smoother, and more refined.

As a cosmetic brand, we focus on appearance benefits rather than anti-aging claims. However, copper peptides like GHK-Cu are amino acid complexes studied in research on tissue processes and dermal fibroblast activity, working through specific peptide signaling pathways. Other ingredients like vitamin C work as antioxidants, hyaluronic acid provides hydration, and ceramides support skin barrier function. Our Face Tonic focuses exclusively on peptide technology (GHK-Cu + Matrixyl 3000) studied for facial skin appearance, allowing you to layer other ingredients separately based on your individual needs.

Absolutely. Our Face Tonic with GHK-Cu and Matrixyl 3000 can be used alongside our Hair Tonic containing GHK-Cu and Acetyl Tetrapeptide-3. This creates a comprehensive peptide routine supporting both facial skin appearance and hair appearance. Apply Face Tonic to clean facial skin and Hair Tonic to clean scalp, each taking under 30 seconds daily. Learn more about combining peptide complexes on our copper peptide hair serum page.
