COPPER PEPTIDE OVERNIGHT TECHNOLOGY
GHK-Cu is the copper tripeptide your skin recognises as a repair signal. This overnight resurfacing mask pairs 1% 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.

Overnight copper peptide system
The GHK-Cu mask takes the copper peptide story and makes it overnight-specific: 1% Copper Tripeptide-1, two supporting peptides, Alpha-Arbutin, four hyaluronic acid forms, Ceramide NP and squalane in a richer formula made for one to four nights per week.
Copper peptide gets the attention, but a leave-on overnight mask also needs hydration, comfort and a support system that makes people want to use it consistently.
This mask uses 1% Copper Tripeptide-1 with Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Alpha-Arbutin, four hyaluronic acid forms, Ceramide NP and squalane for a more complete overnight copper peptide ritual.
Built as a copper peptide sleep step with support peptides, hydration and comfort ingredients.
A product can look like a copper peptide mask and still rely mostly on colour and a surface-level story.
OVERNIGHT COPPER PEPTIDE FORMULA
1% 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.

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.”
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
Overnight ingredient notes
The mask takes the approved GHK-Cu story and makes it sleep-specific: 1% Copper Tripeptide-1, two support peptides, Alpha-Arbutin, four hyaluronic acid forms, Ceramide NP and squalane in a richer overnight format.
The GHK-Cu serum is the daily copper peptide step. The mask is the overnight ritual: richer, more cushiony, and made for the nights you want your routine to feel a little more serious without adding ten steps.
It is tailored to sleep, not copied from the serum page. Think of it as copper peptide care with extra hydration, comfort and a soft morning finish.
This mask uses 1% Copper Tripeptide-1. That is the blue copper peptide ingredient people recognise, and it is the reason the formula has such a distinctive look.
We keep the language grounded: copper peptide skincare for skin that you want to look firmer, smoother, fresher and more polished. No wild claims, no pretending a mask is a clinic service.
Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 support the copper peptide story for visible bounce, softness and smoother-looking texture. They make the mask feel more complete than a single-hero product.
That matters because overnight formulas need to be both active-feeling and wearable. If it feels like too much, it will sit in the drawer. This is made to be used.
Alpha-Arbutin is included for tone support and a more even-looking, luminous finish. It gives the mask another reason to exist beyond “blue peptide product”, especially for people who want overnight care that helps the skin look more polished.
It is not the loudest ingredient in the room. It is the quiet detail that makes the formula feel smarter.
The mask includes Sodium Hyaluronate, Hydrolyzed Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer and Sodium Acetylated Hyaluronate. That gives the hydration story more dimension than a basic single-HA formula.
This is the plush part of the mask: the part that helps skin feel bouncy, cushioned and not tight when you wake up.
Copper peptide formulas can sound intense, but the supporting base matters. Ceramide NP and squalane help the mask feel soft, comforting and more barrier-minded.
That is important for a product you leave on while you sleep. It needs to feel like a treat, not homework.
Use the GHK-Cu Overnight Mask one to four nights per week. That rhythm keeps it special, realistic and easier to commit to.
On non-mask nights, keep your routine simple. The point is consistency over time, not using more product than your skin needs.
If you have the GHK-Cu Serum, apply it first and give it a minute to settle. Then apply the mask as your final step.
If you are using strong vitamin C, retinol or exfoliating acids, keep those in a separate routine at first. The mask is already an active-feeling overnight step, so let it have the night.
GHK-Cu mask questions
The practical questions people ask before adding the GHK-Cu mask to one to four nights per week.
It is a leave-on overnight mask built around 1% Copper Tripeptide-1, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, Alpha-Arbutin, four hyaluronic acid forms, Ceramide NP and squalane.
The serum is the lighter daily peptide step. The mask is richer and more cushiony, made for one to four nights per week when you want extra overnight comfort and hydration.
Use it one to four nights per week. That cadence keeps the mask realistic and special without making people feel like they need to use it every night.
Yes. Apply the GHK-Cu Serum first, let it settle for about a minute, then apply the mask as your final step.
The blue tone comes from Copper Tripeptide-1. It is a normal visual cue of a copper peptide formula.
Alpha-Arbutin is included for tone support and a more even-looking, luminous finish. It gives the overnight formula another cosmetic role beside the copper peptide story.
The mask includes Sodium Hyaluronate, Hydrolyzed Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer and Sodium Acetylated Hyaluronate for a bouncy, hydrated-feeling finish.
They help the mask feel comfortable, soft and more barrier-minded, which matters in a leave-on overnight formula.
Keep strong vitamin C, retinol and exfoliating acids in a separate routine at first. Use the mask on quieter nights so the copper peptide system has space.
If you are pregnant, breastfeeding, trying to conceive or under medical care, check with your healthcare professional before introducing active skincare.
