CKYN BY CYNRGEN
Your Skin Runs
on Science
A complete GHK-Cu protocol designed to help skin look hydrated, smoother, more radiant, and visibly firmer over time.
A three-step GHK-Cu protocol for skin that looks hydrated, smoother, and visibly firmer.
Morning lotion. Night-time serum. Daytime tallow balm.
Your body already knows this peptide. We concentrated it.
GHK-Cu is a copper peptide found naturally in human plasma. Your body produces it throughout your life, but levels decline with age. CKYN replenishes it topically, at concentrations designed to contribute to visible change in the appearance of skin firmness, smoothness, and quality.
Each formula pairs GHK-Cu with a complementary bioactive selected for a specific job: manuka honey for barrier hydration, grass-fed tallow for deep nourishment, hyaluronic acid for overnight renewal. Every ingredient earns its place.
The result is a system where fewer ingredients means higher concentration per milliliter, and higher concentration means the difference shows up in the mirror.
Meticulously chosen bioactives.
Other brands pad their labels with 30 ingredients. Not us. Every ingredient in CKYN earns its place, backed by published research, formulated at concentrations that produce visible change, and designed to amplify each other.
Morning prepares. Daytime defends. Nighttime renews.
Each product amplifies the next. The protocol creates compound results that no single product, at any price, can match.
Your body produced more of this peptide when you were younger.
GHK-Cu is a copper tripeptide found naturally in human plasma. Levels peak in your 20s and decline steadily from there. Published research associates it with visibly firmer, smoother, more youthful-looking skin. CKYN reintroduces it topically, at the concentrations that produce visible results.
What GHK-Cu Does
First identified in human plasma in 1973 by Dr. Loren Pickart, GHK-Cu is a tripeptide-copper complex your body produces naturally. Published studies associate it with visible improvements in the appearance of skin firmness, a more elastic-looking complexion, and overall complexion quality.
Extensive published research has made GHK-Cu one of the most studied compounds in cosmetic peptide science. It is the foundational active in every CKYN formula because the evidence base is deeper than any trending ingredient on the market.
Your Skin Runs on Science.
GHK-Cu is one of the most studied peptides in cosmetic science. Key findings from peer-reviewed research.
GHK-Cu has been studied in published, peer-reviewed cosmetic science. Individual results vary. These statements refer to the ingredient GHK-Cu as studied in published literature and are not claims about CKYN products specifically.
What goes into every bottle. And what stays out.
Backed by Research
GHK-Cu is one of the most studied peptides in peer-reviewed cosmetic science. This is not a trending ingredient.
Intentional Ingredients
No filler ingredients, no added fragrance, no label padding. Every ingredient earns its place, backed by published research.
Cruelty-Free
No animal testing at any stage of development or production.
Small-Batch Blended
Small-batch blended in our Florida facility.
Formulated at Concentration
GHK-Cu at levels designed to produce visible change. Not trace amounts added for label claims.
Biocompatible by Design
Grass-fed tallow mirrors your skin's own lipid structure. GHK-Cu is a peptide your body already recognizes.
Before you decide.
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 become apparent between weeks four and eight with consistent use. The full protocol accelerates this timeline compared to using a single product.
Why do you use fewer ingredients than most skincare brands?
Concentration matters more than ingredient count. Most skincare brands dilute across 20-30 ingredients to build a longer label. We formulate around GHK-Cu at meaningful concentrations, then select a small number of complementary bioactive ingredients chosen because they amplify each other and earn their place through published research. Nothing is there for marketing.
Do I need all three products?
Each product works on its own. The protocol works better. The Morning GHK-Cu Perfecting Lotion handles hydration and protection. The Daytime GHK-Cu Tallow Balm addresses barrier nourishment whenever skin feels dry or stressed. The Night-Time GHK-Cu Firming Serum supports overnight renewal and visible firming. Together they cover every phase of your skin's daily cycle, delivering GHK-Cu and our complementary bioactive ingredients three times a day. Your skin absorbs what it can in each application. Three applications compound what a single product cannot.
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. The formulations are designed to visibly improve the appearance of firmness, barrier health, and hydration. Those goals are universal.
What is GHK-Cu?
GHK-Cu is a copper peptide that naturally occurs in human plasma. Your body produces it on its own, but levels decline with age. In cosmetic science, it is one of the most studied peptides for visibly firmer, smoother, more youthful-looking skin. It is the foundation of every CKYN formula.
How does this compare to retinol or vitamin C?
Retinol and vitamin C are effective but come with trade-offs: irritation, sun sensitivity, oxidation. GHK-Cu works differently. It is naturally biocompatible, is not known to cause photosensitivity, and supports a visibly improved-looking complexion without the adjustment period many actives require. GHK-Cu has been studied alongside retinol and vitamin C in published appearance-of-firmness research.
Why is the tallow balm $144?
The grass-fed tallow is sourced from pasture-raised cattle and rendered specifically for cosmetic use. Combined with concentrated GHK-Cu at effective levels, the cost reflects what goes into the jar. A small amount goes a long way. Most people use one jar over 6-8 weeks.
