The Complete System
The Complete CKYN Protocol
All three GHK-Cu formulas in one system. Morning prepares, daytime defends, nighttime renews, for skin that looks hydrated, smoother, and visibly firmer over time.
- GHK-Cu Perfecting Lotion — morning hydration and priming (30 ml)
- GHK-Cu Tallow Balm — daytime nourishment and defense (56 g)
- GHK-Cu Firming Serum — overnight recovery and firming (59 ml)
- GHK-Cu delivered three times a day, where a single product delivers once
Three formulas. One protocol.
Each product works on its own. Together, they cover every phase of your skin's daily cycle.
GHK-Cu Perfecting Lotion
Protect and hydrate. The everyday foundation that primes your skin.
GHK-Cu Tallow Balm
Nourish and defend. Ancestral wisdom meets clinical science.
GHK-Cu Firming Serum
Recover and renew. Overnight firming with methylene blue.
Compound results a single product can't match.
Absorption has a ceiling
Your skin absorbs a finite level of actives per application. One product, at any concentration, can only deliver so much at once.
Three doses compound
Applying GHK-Cu and its complementary bioactives morning, daytime, and night delivers actives three times across the day, compounding what a single product cannot.
Every phase is covered
Morning prepares. Daytime defends. Nighttime renews. Together the three cover every phase of your skin's daily cycle.
Your skin runs on science.
GHK-Cu is a copper tripeptide found naturally in human plasma. Levels peak in your 20s and decline from there. Over forty years of published research make it one of the most studied compounds in cosmetic peptide science.

Before you decide.
Do I need all three products?
Each product works on its own. The protocol works better. The Morning Perfecting Lotion handles hydration and protection. The Daytime Tallow Balm addresses barrier nourishment whenever skin feels dry or stressed. The Evening Firming Serum supports overnight renewal and visible firming. Your skin absorbs what it can in each application, so three doses a day compounds what a single product cannot.
Is the system cheaper than buying the products separately?
The system is $399, the combined price of all three products. It is designed as the complete protocol in one purchase and one shipment, and Subscribe & Save takes 15% off the whole system.
When will I see results?
Most people notice a hydration and texture difference within the first two weeks. Visible improvements in firmness and fine lines typically appear between weeks four and eight with consistent use. The full protocol accelerates this timeline compared to using a single product.
Can I subscribe?
Yes. Subscribe & Save applies to the complete system at 15% off, so your protocol replenishes automatically and you never interrupt your results by running out.
Is this for men and women?
Yes. Skin biology works the same way regardless of gender. There are no gendered fragrance profiles or unnecessary additives.
