PLU Face Tonic and Hair Tonic - Complete copper peptide system

The Complete Copper Peptide System for Skin and Hair

Research published in the International Journal of Molecular Sciences examines GHK-Cu (copper tripeptide-1), describing its role in collagen production pathways and tissue remodeling processes that support the appearance of both skin and hair when applied topically.

PLU Laboratories formulated our complete system to combine GHK-Cu with complementary peptide complexes. Face Tonic pairs GHK-Cu with Matrixyl 3000 for skin firmness appearance, while Hair Tonic combines GHK-Cu with Acetyl Tetrapeptide-3 for hair density support. Our dual-peptide approach delivers clinically studied concentrations without dilution from hyaluronic acid or other fillers that reduce peptide efficacy.

PLU complete copper peptide system for skin and hair

GHK-Cu Copper Tripeptide-1

The foundation of both copper peptide products. Research describes GHK-Cu as a naturally occurring copper peptide complex studied for its role in collagen production and wound healing processes. Active ingredient in both Face Tonic and Hair Tonic at clinically studied concentrations.

Matrixyl 3000 for Skin

Featured in Face Tonic, this complementary peptide complex has been studied for its role in supporting skin texture appearance. Research suggests these amino acids may help improve how skin firmness appears with consistent topical application.

Acetyl Tetrapeptide-3 for Hair

Featured in Hair Tonic, this biomimetic peptide complex has been studied in research examining hair follicle activity. Combined with GHK-Cu, it creates a dual copper peptide system that addresses hair growth appearance through multiple amino acid signaling pathways.

No Hyaluronic Acid Dilution

Many copper peptide serums dilute active ingredients with hyaluronic acid and botanical extracts. Our formulations exclude these fillers to maintain the peptide concentrations studied in clinical research. Layer additional products separately if desired.

Clinically Studied Concentrations

Both products use GHK-Cu and complementary peptides at concentrations consistent with published research. This ensures the copper peptide complex can work through the pathways examined in clinical literature on skin care and hair appearance.

Complete System Benefits

Using both copper peptide products creates comprehensive support where Face Tonic addresses skin firmness appearance and Hair Tonic supports hair density. Total application time under one minute daily for complete peptide coverage.

Why Our Copper Peptide Products Exclude Common Additives

Many copper peptide serums dilute their active ingredients with hyaluronic acid, botanical extracts, and other fillers. While these aren't harmful, they reduce the concentration of what clinical research actually studied: copper peptides and complementary amino acids at specific concentrations.

The IJMS research examined GHK-Cu as a copper peptide complex, not as part of a blend with hyaluronic acid or other additives. PLU Laboratories keeps our formulations focused on clinically studied concentrations. If you want additional hydration or other benefits, you can layer those products over our copper peptide products, maintaining the integrity of the peptide concentrations while customizing your routine.

Why We Started PLU Laboratories

In 2021, one of our founders decided something had to change. He'd tried minoxidil but dealt with scalp irritation. After diving into published research on GHK-Cu and copper peptides, he knew he'd found something different.

But sourcing quality copper peptides meant ordering from overseas suppliers - some delivered poor quality product, others took months to arrive. Finding reliable sources meant navigating 6-8 week shipments, clearing customs, and hoping concentrations matched what he ordered.

He committed to consistent daily use. Four years later, the transformation speaks for itself.

We started PLU Laboratories because everyone deserves access to research-backed copper peptide formulations without the frustration of trial and error - and without settling for poor quality or diluted products. Once we perfected our Hair Tonic formulation, we developed Face Tonic using the same dual-peptide approach - combining GHK-Cu with Matrixyl 3000 to support skin firmness appearance.

Common Questions About Our Copper Peptide Products

What are copper peptide products and how do they work? +

Copper peptide products contain GHK-Cu (copper tripeptide-1), a naturally occurring complex of three amino acids (glycine, histidine, and lysine) bound to copper. Research published in the International Journal of Molecular Sciences describes how GHK-Cu works through amino acid signaling pathways that support collagen production and tissue remodeling processes when applied topically to skin and scalp.

Our copper peptide products use a dual-peptide approach: Face Tonic pairs GHK-Cu with Matrixyl 3000 for skin firmness appearance, while Hair Tonic combines GHK-Cu with Acetyl Tetrapeptide-3 for hair density support. The peptides work gradually through biological pathways studied in clinical research, not through immediate cosmetic effects.

Which product should I start with - Face Tonic or Hair Tonic? +

Start with whichever addresses your primary concern. If you're focused on skin firmness appearance and fine lines, Face Tonic is your priority. If hair density and scalp health are your main concerns, start with Hair Tonic.

Both products use GHK-Cu as the core active ingredient, just paired with different complementary peptides. Face Tonic combines GHK-Cu with Matrixyl 3000 for skin, while Hair Tonic pairs GHK-Cu with Acetyl Tetrapeptide-3 for hair. Most customers eventually use both as a complete system since they work through similar pathways studied in the same research.

Why don't your products contain hyaluronic acid? +

The research on copper peptides examined GHK-Cu at specific concentrations, not diluted with hyaluronic acid or other fillers. Adding hyaluronic acid reduces the peptide concentration that clinical studies actually tested.

Our approach keeps formulations focused on the active ingredients backed by published research. If you want hyaluronic acid's hydration benefits, you can layer it over our copper peptide products after they absorb. This gives you control over your routine while maintaining the peptide concentrations studied in clinical literature.

Can I use these with retinol or vitamin C? +

Yes. Apply your copper peptide product first to clean skin, wait 60 seconds for absorption, then layer other active ingredients like retinol or vitamin C. The focused formulations are designed to work alongside other skin care products without the compatibility concerns that come with pre-mixed multi-ingredient serums.

Some people use Face Tonic in the morning and retinol at night to avoid any potential interaction, though there's no documented conflict between copper peptides and other actives when applied separately.

How long until I see results? +

Most users report visible improvements within 6-12 weeks of consistent daily use. The research on copper peptides describes gradual processes where amino acid signaling pathways work over time to support tissue appearance.

Early changes like improved skin texture or healthier-looking hair may appear within 2-4 weeks. More significant improvements in skin firmness appearance or hair density typically develop between weeks 8-12. Results require consistent daily application because the peptides work through biological pathways that need ongoing support.

Will these work for sensitive skin, and do they cause side effects? +

Our copper peptide formulations exclude common irritants like propylene glycol (found in minoxidil) and unnecessary fragrances or botanical extracts that can trigger sensitivities. The focused ingredient lists typically work well for sensitive skin types.

However, if you have known skin sensitivities or a sensitive scalp, perform a patch test before full application. Apply a small amount to a discrete area and wait 24 hours. If irritation occurs, discontinue use. Unlike minoxidil which causes skin irritation in 13.8% of users, copper peptide products generally have better tolerability profiles when formulated without common irritants.

What makes your formulation different from other copper peptide brands? +

Most copper peptide serums dilute their active ingredients with hyaluronic acid, botanical extracts, or other fillers to create longer ingredient lists. We focus exclusively on the concentrations studied in clinical research.

Our dual-peptide approach pairs GHK-Cu with complementary peptides (Matrixyl 3000 for Face Tonic, Acetyl Tetrapeptide-3 for Hair Tonic) at concentrations consistent with published studies. This focused formulation strategy ensures the copper peptide complex can work through the mechanisms examined in research, without interference from unnecessary additives.

Can I use both products together in the same routine? +

Yes. Both products are designed to work as a complete system. Apply Face Tonic to clean facial skin and Hair Tonic to clean scalp. Total application time is under one minute for both products.

Many customers use Face Tonic in the morning as part of their skin care routine and Hair Tonic at night before bed. This creates consistent peptide delivery across 24 hours while fitting seamlessly into existing routines. Both use GHK-Cu as the core ingredient, so you're getting complementary peptide support for both skin and hair appearance.

Can copper peptides be injected? Are these products safe for injection? +

No. Our products are formulated exclusively for topical application and are NOT safe for injection. Do not attempt to inject these products under any circumstances.

While some medical practices use copper peptide injections, those are pharmaceutical-grade preparations specifically formulated and sterilized for injection. Our Face Tonic and Hair Tonic are topical formulations designed to be applied to skin and scalp surfaces only.

The research we reference examines topical copper peptide application, not injectable forms. Our products provide a topical approach to explore before considering invasive procedures, but they are fundamentally different from injectable preparations and must never be used for injection.
