COPPER PEPTIDE OVERNIGHT TECHNOLOGY
GHK-Cu is the copper tripeptide your skin recognises as a repair signal. This overnight resurfacing mask pairs 1.2% Copper Tripeptide-1 with Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Alpha-Arbutin, four forms of hyaluronic acid and Ceramide NP, so the formula does more than hydrate — it supports renewal, firmness, brightness and barrier recovery while you sleep.
ADD TO BAGSTAR INGREDIENT SPOTLIGHTS
The GHK-Cu mask is built around copper peptide repair, signal peptides, tone refinement, layered hydration and barrier support — each active earns its place.
01 · Signature Active
The blue peptide everyone is talking about — at a serious 1% concentration, built for overnight renewal, bounce and visibly smoother skin by morning.
02 · Firmness Peptide
The bounce-back peptide. Helps skin look firmer, smoother and more supported — exactly what you want in a regenerative overnight mask.
03 · Calming Peptide
The comfort peptide. Supports a calmer, more resilient-looking finish so renewal feels plush — not stripped.
04 · Tone Refinement
The glow-up active. Added for uneven tone, post-blemish marks and that clearer, fresher look customers actually notice.
05 · Hydration Matrix
Four hydration textures in one formula, so skin feels juicy, cushioned and visibly plumper when you rinse in the morning.
06 · Barrier Lipid
The barrier closer. Helps seal in comfort so this feels like a luxe recovery mask, not an aggressive treatment.

Generating overnight mask score
This is a very strong GHK-Cu leave-on mask formula. With the final INCI and confirmed 1.2% GHK-Cu, the saved formula review scores it 9.6/10. Potentially 9.8/10 if final pH, stability, colour stability, packaging, preservative challenge testing and long-term texture are all locked in.
The formula has a complete overnight comfort, hydration, peptide, barrier and glow-support structure. With 1.2% GHK-Cu, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, four types of hyaluronic acid, Polyglutamic Acid, Ceramide NP, Squalane, Niacinamide, Panthenol, Alpha-Arbutin, Ascorbyl Glucoside, Beta-Glucan, Madecassoside, Centella compounds and Adenosine, it reads like a premium overnight mask rather than a simple hydrating gel.
1.2% GHK-Cu / Copper Tripeptide-1 is the main reason the score is high. For a leave-on overnight mask, it is a strong positioning point and supports the firmer-looking, smoother-looking and refreshed-looking skin story.
Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 add a useful supporting peptide story. Because their exact levels are not declared here, the saved review treats them as strong supporting peptides rather than a total peptide percentage claim.
Four types of hyaluronic acid plus Polyglutamic Acid create the hydration architecture. This supports a cushiony, bouncy, dewy and more moisturised skin feel in an overnight mask format.
Ceramide NP, Squalane, Panthenol, Beta-Glucan, Madecassoside and Centella make the formula feel comforting and complete. This helps position the mask for skin that looks tired, dry or stressed.
Niacinamide, Alpha-Arbutin, Ascorbyl Glucoside, Tocopherol and Phytic Acid give the GHK-Cu mask a stronger glow and more even-looking tone story than a peptide-only overnight product.
Ingredient quality: 9.7/10. GHK-Cu strength: 9.8/10. Peptide support: 9.3/10. Hydration system: 9.7/10. Barrier support: 9.6/10. Comfort support: 9.6/10. Glow support: 9.4/10. Formula concept: 9.7/10. Premium positioning: 9.8/10. Final saved formula score: 9.6/10.

Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 support the GHK-Cu story with smoother-looking and firmer-looking skin benefits.
Four types of hyaluronic acid, Polyglutamic Acid, Ceramide NP and Squalane make the mask feel more complete than a basic gel mask.
Niacinamide, Alpha-Arbutin, Ascorbyl Glucoside, Tocopherol and Phytic Acid give the formula a broader glow and more even-looking tone story.

OVERNIGHT COPPER PEPTIDE FORMULA
1.2% pure GHK-Cu, two signal peptides, Alpha-Arbutin, four forms of hyaluronic acid and Ceramide NP in one overnight mask.
The signature copper peptide at the heart of the formula. Supports skin repair signalling, firmness and post-stress recovery while the overnight mask keeps it in contact with skin for hours.
A matrikine signal peptide used to support collagen production, firmness and smoother-looking texture. It pairs with GHK-Cu without competing for the same pathway.
Helps calm visible stress and supports the look of firmer, more resilient skin. Together with PT-1, it rounds out the multi-peptide resurfacing story.
Supporting Actives
A targeted tone-evening active that helps reduce the look of uneven pigmentation and post-blemish marks while the mask supports overnight renewal.
Sodium Hyaluronate, Hydrolyzed Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer and Sodium Acetylated Hyaluronate hydrate across multiple layers overnight.
A skin-identical lipid that helps reinforce the barrier, reduce overnight moisture loss and keep resurfacing actives feeling comfortable.
Plant-derived emollient that mimics skin's natural sebum. Locks in the mask formula without congesting pores.
Soothes, repairs the barrier and locks in moisture — essential when the mask is working on cellular renewal overnight.
A calming recovery complex that supports visible redness, stressed skin and barrier resilience alongside the copper peptide pathway.
A soothing polysaccharide that supports hydration, comfort and barrier recovery, especially useful in an overnight resurfacing formula.
Supports barrier strength, brightness and oil balance, complementing Alpha-Arbutin and the peptide complex for a more even-looking finish.

YOUR NIGHT RITUAL
Double cleanse in the PM. Start with an oil cleanser to remove SPF and makeup, then your Helloskin cleanser. Apply the mask to clean, dry skin.
Optional: apply your GHK-Cu serum first, allow 1 minute to absorb. Apply the mask generously over the face and neck — do not rub, press gently.
Leave on overnight — 6 to 8 hours. Rinse with lukewarm water in the morning. Follow with moisturiser and SPF 30+.
EXPECTED RESULTS
Skin calmer and softer on waking. GHK-Cu's anti-inflammatory effect reduces overnight redness and sensitivity. Barrier begins to repair.
Texture visibly smoother. The GHK-Cu and signal peptide complex supports renewal while the hyaluronic acid network keeps skin looking plump.
Visible firmness, glow and more even-looking tone. Alpha-Arbutin and Ascorbyl Glucoside support brightness while Ceramide NP keeps the barrier resilient.
💡 Pro Tips
Use 3–4 nights per week — copper peptides need recovery time between applications
Do not use on the same night as exfoliating acids — alternate nights for best results
Pairs perfectly with the GHK-Cu serum underneath for amplified overnight copper peptide delivery
⚠️ The natural blue tint from Copper Tripeptide-1 does not stain pillows or skin when rinsed properly in the morning
REAL RESULTS
“I've spent a fortune on overnight masks over the years. This is the first one that has actually made a measurable difference to my skin's firmness. By week three, the lines around my eyes had visibly softened. I won't be without it.”
“I use this after microneedling and the recovery is dramatically faster. Redness gone in 24 hours instead of three days. The GHK-Cu is doing exactly what it says on the label.”
“I layer this over the GHK-Cu serum three nights a week. My skin has never looked more even or felt more resilient. My dermatologist asked what I'd added to my routine.”
“I wake up glowing every morning I use this. My skin looks like I've had 10 hours of sleep even when I've had six. The subtle blue tint rinses off completely — no staining.”
CURATED ROUTINE
Cleanse, layer, sleep. Three steps — wake up with your best skin every morning.
pH-balanced, glycerin + aloe base. Double cleanse at night to maximise overnight mask absorption without residue blocking peptide delivery.
1.2% Copper Tripeptide-1, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Alpha-Arbutin, four forms of hyaluronic acid and Ceramide NP.
Layer underneath the mask at night for amplified copper peptide delivery — or use alone in your AM routine to keep skin in continuous repair.
EIGHT HOURS. WHILE YOU SLEEP.
1.2% pure GHK-Cu with signal peptides, Alpha-Arbutin, four forms of hyaluronic acid and Ceramide NP. Overnight resurfacing support without starting from scratch every morning.
