Contains naturally anti-inflammatory compounds that help calm irritation and support skin recovery.
Adeps Bovis (Beef Tallow), Raw Honey (Mel), Butyrospermum Parkii (Shea) Butter, Cera Alba (Beeswax), Simmondsia Chinensis (Jojoba) Seed Oil, Tocopherol (Vitamin E), Copper Tripeptide-1 (GHK-Cu), Aqua (Filtered Water), Butylene Glycol, Calendula Officinalis Extract, Centella Asiatica Extract, Cetraria Islandica Extract (Iceland Moss), Hydrolyzed Collagen.
GHK-Cu was discovered in 1973 by Dr. Loren Pickart.
It naturally occurs in human blood plasma at around 200 ng/ml by the age of 20, but declines to below 80 ng/ml by the age of 60.
More than 100 scientific studies have shown its effects on over 4,000 human genes involved in collagen synthesis, tissue repair, and inflammation control.
Our concentration: 1% (600 mg per 60 ml).
That is 5 to 50 times higher than most peptide products commonly found in drugstores.
Not the highest concentration on the market — but one of the most transparent.
Apply morning and evening after cleansing.
Take a small amount (a thin layer) from the jar and apply to the face, neck, and décolleté. Gently massage into the skin.
The tallow-based formula supports the natural skin barrier and absorbs fully without leaving a greasy residue.
Tip
During the day, combine with a separate sunscreen if needed.
In the evening, use as the final step in your routine.
Important Notice
Do not use at the same time as high-dose Vitamin C (L-Ascorbic Acid) or strong acids (AHA/BHA).
These may reduce the effectiveness of copper peptides.
Recommended: acids in the morning, copper peptides in the evening.
When will results become visible?
Initial skin barrier improvements may appear after 4–6 weeks.
For visible collagen support: 8–12 weeks with consistent use.
Copper peptides work on a cellular level — consistency is key.
How long does one jar last?
One jar (60 ml) lasts approximately 6–8 weeks with daily use.

Grass-fed tallow + raw honey + shea butter. Your skin's fatty acid profile, mirrored. No synthetic fillers.
Not acne suppression. Repair from within. No dryness, no stripping. Barrier repair, collagen synthesis, anti-inflammation — by week four, you'll see the difference.
Most moisturizers sit on the surface. CU Tallow speaks your skin's own lipid language — and signals it to rebuild from within.
GHK-Cu stimulates production of collagen I, III, and V — the proteins responsible for skin firmness and elasticity.
Tallow's fatty acid profile mirrors human sebum. It absorbs where synthetic emollients just sit on top. Your barrier rebuilds.
GHK-Cu reduces inflammatory cytokines. Calms redness, acne, rosacea, and irritation at the cellular level.
Raw honey and shea butter lock in moisture. Jojoba oil balances sebum production. No synthetic humectants needed.
Soothes post-shave irritation on contact. GHK-Cu accelerates micro-wound healing while tallow restores the skin barrier daily shaving strips away.
GHK-Cu accelerates tissue remodeling. Supports healing of acne scars, post-inflammatory marks, and sun-damaged skin over 8–12 weeks.
Every ingredient has a function. No fillers. No synthetic fragrance. The concentration is on the label.

Our concentration vs. mass market
GHK-Cu — 10–100x above drugstore average
GHK-Cu was discovered in 1973 by Dr. Loren Pickart. Over 100 studies confirm its effects on collagen, wound healing, and gene expression.
Pickart et al. (2012): GHK-Cu activates over 4,000 human genes involved in tissue remodeling, collagen synthesis, and anti-inflammatory response.
Abdulghani et al. (1998): Topical GHK-Cu improved skin thickness, firmness, and reduced fine lines in a 12-week clinical trial.
Leyden et al. (2003): Copper peptide cream outperformed vitamin C and retinol in increasing collagen production over 12 weeks.
"Men's skin is 20% thicker than women's, produces more sebum, and takes daily micro-damage from shaving. Yet most men use nothing — or the wrong products. GHK-Cu is a signaling peptide that tells skin to produce collagen, calm inflammation, and repair barrier damage. In a tallow carrier that mirrors the skin's own lipid profile, you get bioavailability that water-based serums can't match. For acne scarring, razor irritation, and early aging — this is the formulation I'd recommend."
No 10-step routine. Just one product that does three things at once.
Start with clean, slightly damp skin
1–2 pumps on face, neck, and jawline
Gently massage until fully absorbed
Morning and/or evening. 8–12 weeks for collagen results
"Had cystic acne scars since I was 19. Nothing worked — not microneedling, not retinol. 10 weeks of CU Tallow and my skin is visibly smoother. My barber noticed before I did."
"Razor burn every single day for 15 years. Tried every aftershave, every balm. CU Tallow after shaving — no more redness, no more bumps. Genuinely wish I found this sooner."
"I'm 42 and never had a skincare routine. My wife bought this for me. 6 weeks in — the lines on my forehead are less deep, skin feels thicker. I look less tired. Now I actually use it daily."
"Good product. Takes patience — first 3 weeks I didn't see much. But week 6+ my acne scarring is fading and skin texture is way better. 4 stars for now, will update at week 12."
"Post-Accutane my skin was destroyed. Burning, peeling, everything made it worse. CU Tallow was the only thing that didn't sting. 8 weeks later my barrier is back. Skin actually feels normal again."
"Eczema on my jawline and neck for years. Cortisone made it thinner. This is the first thing that actually rebuilt the skin instead of just suppressing symptoms. Calm, thick, healthy skin."
"The 1% concentration sold me. Every other brand hides behind 'contains peptides' with 0.01%. This one puts it on the label. My skin at 44 looks better than at 38. Third jar ordered."
"Construction worker. My skin takes a beating — sun, wind, dust. Started using this at night. Rough patches gone in 3 weeks. Skin heals faster from cuts too. No-nonsense product."
