Is 3% GHK-Cu better than a lower strength?

No. Copper peptides work at low concentrations and the research suggests a ceiling past which more gives you nothing. We make 3% for people who have been using it for a long time and want a more concentrated option to use less often. Most people do very well on 0.5% or 1% and never need to move.

Can I start with the 3% serum?

We'd rather you didn't. Start on the 0.5% and give it three months of consistent use. If your skin is comfortable there, move to the 1%. The 3% is for people who have already done that.

How often should I use a 3% copper peptide serum?

Twice a week to begin with, and stay there for a month. Two or three times a week is where most people settle at this strength. A higher concentration is a reason to use it less often.

Copper Tripeptide-1, a small peptide bound to copper that occurs naturally in the body. Levels are highest in early adulthood and fall away with each decade, which is part of why it became interesting to skincare. It has been studied since the 1970s and the blue colour of any copper peptide serum comes from the copper itself.

Why does this serum only have eleven ingredients?

Because that's all it needs. Every ingredient is either the peptide, something that keeps the peptide stable, or something that makes it comfortable to wear. There's no fragrance, no silicone, no PEGs and no colour. The blue comes from the copper.

What does it feel like on the skin?

Cold and thin straight from the fridge. It goes on like water and settles into a light cushion of hydration that stays for hours. There's no oil or silicone in it, so it doesn't sit heavily or congest, and it layers under an oil or moisturiser without pilling.

Can I use copper peptides with vitamin C, niacinamide or retinol?

Niacinamide is fine alongside it. Traditional ascorbic acid needs a low pH that pulls copper peptides apart, so those two don't belong in the same step — our vitamin C uses THD ascorbate, which is stable at skin pH and can go straight over the top. Retinoids can follow the copper peptide, or run on alternate nights.

Why is the serum blue, and will it stain?

The blue is the copper in the peptide itself. We don't add colour. It won't stain skin at normal use levels, though keep it off pale fabric while it dries. If it shifts to brown or green the peptide has degraded and the bottle needs replacing.

Do I need to worry about copper building up in my skin?

Topical copper peptides used as directed aren't associated with copper accumulating in healthy skin. Anyone with Wilson's disease or a known copper sensitivity should avoid copper peptide products altogether. If you have a diagnosed condition, check with your healthcare provider.

How long before I notice anything?

Copper peptides are slow. Three months of consistent use before you judge it, at any strength. Going stronger doesn't shorten that.

Does it need to be refrigerated?

Yes. Fridge after opening, and use it within three months. We make in small batches without synthetic stabilisers, so cold storage is what keeps the peptide intact.

3% GHK-Cu in eleven ingredients. The strongest we make.

I'm a naturopath. I made this because I wanted a high-strength copper peptide I was happy putting on my own face, and I couldn't find one.

I'm a naturopath and nutritionist and I still run a private practice alongside making skincare.

The range started because I wanted to use high-strength actives and kept putting bottles back on the shelf. Strong formulas came with long ingredient lists. Clean formulas came at strengths that weren't worth the money. I couldn't find both in one bottle, so I started making them.

This is the strongest thing we make. Three percent GHK-Cu in a soothing & hydrating water based gel.

If you've been on our 0.5% or 1% for a while and wondered what's past it, this is what's past it.

If you haven't, start there. Beginners do better on less and I'd rather sell you the right bottle.

Cold from the fridge it goes on feeling deliciously soothing and light, settling into a soft cocoon of hydration that stays for hours. That part happens the first night. The peptide is slower. Give it three months before you decide anything.

Key ingredients

Copper Tripeptide-1 (GHK-Cu) 3% - The same peptide your skin already makes, and makes less of every decade

Sodium Hyaluronate - Hyaluronic acid that holds water on the surface of your skin to create a silky cocoon of hydration

Trehalose - The hydrating and skin barrier protecting sugar molecule that lets resurrection plants dry to a husk in the desert and come back after rain. It holds water, and it keeps the peptide company in the bottle

Allantoin - A hundred-year-old soothing ingredient originally from the Comfrey plant that has never needed rebranding. It's here so the serum stays comfortable at this strength.

Full INCI: Aqua, Glycerin, Copper Tripeptide-1, Methylpropanediol, Caprylyl Glycol, Trehalose, Phenylpropanol, Sodium Hyaluronate, Sclerotium Gum, Sodium Lactate, Allantoin

Eleven ingredients. No added fragrance, no silicones, no PEGs, no colour - the blue is the copper.

How to use

Onto clean, still-damp skin at night. Follow with an oil. Our vitamin C in olive squalane sits over it well and helps carry the peptide down.

Start at twice a week and stay there a month before increasing the frequency.

If your skin feels tight or looks slack, back off. Go down to the 1% for a while. Nothing has gone wrong.

Shake before use. Keep out of direct sunlight. The blue tells you it's still good - brown or green means it's gone.

Who it's for

You've been consistent on our 0.5% or 1% for three months or more.

Not for you if you're new to copper peptides, if your skin is reactive or already unhappy, or if you're hoping a bigger number gets you there faster. It doesn't.
