Morning prepares your skin for everything after it.

Deep hydration

GHK-Cu and manuka honey work together for a visibly hydrated, supple-looking complexion that holds through the day.

Visibly firmer

GHK-Cu, the copper peptide found naturally in human plasma, is associated with a firmer, more youthful-looking appearance over time.

Primed and protected

A skin-compatible tallow base readies your skin to receive the rest of the protocol, then SPF finishes the morning.

Fewer ingredients. Higher concentration.

Other brands pad their labels with thirty ingredients. Not us. The Perfecting Lotion pairs GHK-Cu with manuka honey for barrier hydration. Every ingredient earns its place.

Cu GHK-Cu · Copper Peptide The peptide your body makes, delivered back at concentration

Glycyl-L-histidyl-L-lysine copper(II), molecular weight 340.38 Da, first identified in human plasma in 1973. Your body produces this peptide naturally and production declines with age. We deliver it back at concentrations designed to produce visibly firmer, smoother, more refined-looking skin.

Four decades of research. Published studies associate GHK-Cu with visibly firmer, more youthful-looking skin, and it outperformed vitamin C and retinoic acid comparators in published firmness trials.

MH Manuka Honey · Deep Hydration New Zealand-sourced humectant for lasting surface moisture

A natural humectant with unique methylglyoxal compounds that contributes to lasting moisture at the surface. The result is skin that looks hydrated and supple through a full day.

Human appearance study. A 2025 study of 40 women using a manuka-based serum for 8 weeks reported improvements in the appearance of fine lines, dark spots, and dryness.

B3 Niacinamide · Tone Support Vitamin B3 for a more even, refined-looking tone

One of the most clinically supported multi-function ingredients in the cosmeceutical literature. It supports a more even, refined-looking complexion in the morning.

Melanosome-transfer mechanism. Niacinamide was shown to reduce melanosome transfer, associated with a brighter, more even-looking tone.

TW Grass-Fed Tallow · Nourishment Base Structurally similar to your skin's own lipids

Rendered from grass-fed, pasture-raised cattle and rich in fat-soluble vitamins A, D, E, and K. Its fatty acid profile mirrors the skin's own lipid barrier, which is why it absorbs without residue and leaves skin looking nourished, not clogged.

Scoping review. A PRISMA-ScR review reported that tallow's fatty-acid composition is biocompatible with the human skin lipid matrix.

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.

Where it fits in your protocol

Your skin rewards consistency. This is one of three daily application windows.

01

Cleanse

Start with clean, dry skin. Pat gently.

02

Apply the lotion

Smooth a thin, even layer over face and neck. A little goes a long way.

03

Follow with SPF

Finish with a broad-spectrum sunscreen before the day begins.

What goes into every bottle. And what stays out.

40+ Years of Research

GHK-Cu has been studied in peer-reviewed cosmetic science since 1973. 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.

Made in the USA

Formulated and manufactured domestically.

Clinical-Grade Concentrations

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 brands?

Concentration matters more than ingredient count. Most brands dilute across 20 to 30 ingredients to build a longer label. We formulate around GHK-Cu at meaningful concentrations, then add one complementary bioactive chosen because it earns its place through published research.

Is GHK-Cu a synthetic chemical?

GHK-Cu is a copper peptide that occurs naturally in human blood plasma. Your body produces it on its own, but levels decline with age. The version used in skincare mirrors that naturally occurring peptide.

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.

Can I use it on its own?

Yes. It works as a standalone morning step, and it is also the foundation of the three-step protocol, engineered so each product amplifies the next.

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.

The Complete CKYN Protocol

Your skin absorbs what it can in each application. Three doses a day compounds what a single product cannot. Morning, daytime, and night in one system.
