GHK-Cu is a naturally occurring tripeptide that declines with age — from around 200 ng/mL at age 20 to below 80 ng/mL by age 60. The result:
• Collagen Production — GHK-Cu supports the synthesis of Type I and III collagen, essential for skin firmness and elasticity
• Wrinkle Support — Hydrolyzed Collagen helps improve skin elasticity and visibly smooth fine lines
• Deep Hydration — Hyaluronic Acid binds up to 1,000 times its weight in water, drawing moisture deep into the skin
• Skin Barrier Support — GHK-Cu helps strengthen the natural skin barrier and reduce transepidermal water loss
• Antioxidant Protection — Copper peptides help neutralize free radicals and support healthy skin aging against oxidative stress
GHK-Cu was first isolated by Loren Pickart in 1973. Since then, numerous studies have explored its role in cellular communication and tissue repair.
Relevant for the scalp:
• Pickart et al. (2012): GHK-Cu was shown to influence a wide range of genes linked to regeneration and hair follicle function
• Pyo et al. (2007): Copper peptides promoted the proliferation of dermal papilla cells — the cells that play a central role in hair growth
• Uno & Kurata (1993): Topically applied copper peptides showed increased hair follicle size and a prolonged anagen (growth) phase in research
Our 0.3% concentration is significantly higher than many conventional formulations (0.01–0.1%), where copper peptides are often used only in minimal amounts.
• GHK-Cu (Copper Peptide): Supports collagen production, skin regeneration, and improved firmness and skin texture.
• Hyaluronic Acid: Provides deep hydration, helps plump the skin, and supports the effectiveness of the peptides.

GHK-Cu + Collagen + Hyaluronic Acid. Three active ingredients, one goal: visibly firmer, plumper skin after every use.
Crystal Sheet Technology. The mask melts on your skin and continuously releases active ingredients — 30 minutes of concentrated care.
5 masks per box. No parabens. No sulfates. For all skin types — including sensitive skin.
No empty promises. Three clinically researched active ingredients that target the root cause — not just the surface.
GHK-Cu and collagen visibly firm the skin. After 30 minutes you feel the difference — firmer contours, plumper skin.
Hyaluronic acid binds 1,000 times its own weight in water. Your skin is plumped from within — full and radiant.
GHK-Cu stimulates the body's own collagen production and reduces fine lines. Not concealing — regenerating.
Copper peptides strengthen the skin barrier and reduce inflammation. Less redness, less irritation.
The combination of niacinamide and allantoin brightens the complexion and soothes irritated skin — for an even skin tone.
Formulated for normal, dry, oily, combination and sensitive skin. Paraben-free, sulfate-free, vegan.
Every ingredient has a function. No fillers.
Stimulates collagen I, III and V. Reduces inflammation markers by up to 70%. Repairs the skin barrier.
Low-molecular collagen penetrates the skin and supports skin density from within — not just the surface.
Binds 1,000 times its own weight in water. Plumps the skin and instantly reduces dryness lines.
No hidden dosages. Everything on the label. Vegan and paraben-free.
Copper peptides — stimulates collagen, repairs skin barrier

Three active ingredients with clinical evidence. Together they create a synergy that isn't possible individually.
Pickart et al. (2012): GHK-Cu suppresses the NFkB signaling cascade and reduces IL-6 and TNF-alpha — the inflammation markers that accelerate skin aging.
Finkley et al. (2005): 67 women, 12 weeks — GHK-Cu improved skin density and significantly reduced fine lines.
Maquart et al. (1988): GHK-Cu stimulates the synthesis of collagen I, III and V in fibroblasts — the building blocks for firm, elastic skin.
Broad Institute (CMAP): GHK-Cu resets approximately 4,000 genes (~32% of the human genome) toward a younger expression pattern.
"Sheet masks have one major advantage over serums: contact time. When GHK-Cu sits on the skin for 15–30 minutes under occlusion, the peptide penetration is significantly higher than a rinse-off or even a leave-on product. Combined with hydrolyzed collagen and hyaluronic acid, you're getting an intensive treatment that addresses firmness, hydration, and barrier function in a single session."
1–2x per week for optimal results. Perfect as a weekly ritual or before special occasions.
Thoroughly cleanse face and pat dry
Unfold mask and place evenly on the face
Leave on for 15–30 minutes. Optional: overnight
Gently massage remaining serum in. Do not rinse off.
"Used it before my wedding. The morning after, my skin looked visibly lifted and glowing. My photographer asked if I'd had a facial. No — just the CU Facial Mask the night before."
"At 61, I've tried every luxury mask on the market. La Mer, SK-II, you name it. This one gives a tighter, plumper result than any of them — and it has actual science behind it, not just fragrance."
"The serum left on my skin after removing the mask lasted all night. Woke up with my skin feeling like it had been to a spa. I use it every Sunday — it's become my ritual."
"Nice mask, feels premium. The lifting effect was subtle after first use but definitely there. After 4 weekly uses it's more pronounced. The price per mask is fair for the ingredients."
"I wore it overnight as suggested. The difference in the morning was dramatic — my nasolabial folds looked significantly softer and my cheeks were visibly plumper. Ordering my third box."
"Combined with CU Tallow afterwards, this is the best anti-aging routine I've found. The mask does the heavy lifting, the tallow seals everything in. My skin at 48 looks better than at 40."
"Bought this for my mom's birthday. She's 65 and never uses skincare. After one mask she called me to say her skin felt 'different — tighter but not dry.' She's now on her second box."
"I'm a dermatology nurse. The ingredient list on this mask is genuinely impressive — GHK-Cu, hydrolyzed collagen, HA, niacinamide, allantoin. No filler ingredients. This is clinical-grade in a consumer format."
CU Facial Mask — GHK-Cu copper peptides with collagen and hyaluronic acid. 5 masks per box. Paraben-free. For all skin types. With a 30-day money-back guarantee.
