MADE IN AU

Apply 1–2 drops directly to clean skin and gently rub in using circular motions. Suitable for AM or PM use. Follow with sunscreen in the morning.

For topical application only. For healthy adults 18+. Patch test before first use. Avoid contact with eyes; rinse thoroughly with water if contact occurs. Discontinue use if irritation occurs. Keep out of reach of children. Store below 25°C, away from direct sunlight. Use within 12 months of opening, or 24 months from the manufacture date — whichever comes first.

THE NUMBERS

A bigger number on the bottle usually means less peptide in it.

GHK-Cu is almost always sold to formulators as a pre-made 1% solution — the peptide is already diluted 100 to 1 before it reaches the lab. So a serum advertising “1% GHK-Cu” is usually telling you how much solution went in, not how much peptide.

1% of a 1% solution is 0.01% peptide. We start from pure GHK-Cu powder, so our 0.2% is 0.2% of the actual peptide — roughly 20 times what is in a “1%” serum. Not because the number matters more, but because you deserve to know which one you're actually buying.

EVERY INGREDIENT, EXPLAINED

All 14. No filler ingredient list, no vague Latin names left unexplained.

Listed in the order they actually appear on the bottle — which is the order of concentration, highest first. Tap any ingredient to see what it does.

What it is: Purified water, the base every ingredient dissolves into.

Solves: Nothing on its own — but it's the honest base weight of the formula, not padded out.

What it is: One of the most studied vitamins in skincare.

Solves: Uneven tone and visible pores — helps brighten and refine skin texture.

What it is: A humectant that pulls moisture in from the air.

Solves: Dry, tight-feeling skin — keeps the formula (and you) hydrated without feeling heavy.

What it is: A soothing, moisture-binding ingredient.

Solves: Irritation and a compromised-feeling barrier — calms and conditions skin.

What it is: Our headline active, at 0.2% pure — not a diluted solution.

Solves: Loss of firmness and fine lines — supports the look of firmer, more elastic skin.

What it is: A widely used, low-irritation preservative.

Solves: Keeps a water-based formula safe from bacteria and mould — unglamorous, but necessary and disclosed.

What it is: A mild conditioning agent that also boosts preservative performance.

Solves: Lets us use less preservative overall while keeping the formula stable.

What it is: A smaller, faster-absorbing form of hyaluronic acid.

Solves: Dehydration and dullness — draws moisture in so skin feels plumper.

What it is: A plant-derived thickener.

Solves: Nothing for your skin directly — it's why the serum has texture instead of running like water. Included because we'd rather explain a texture ingredient than hide it.

What it is: A gentle, naturally-derived skin-conditioning agent.

Solves: Sensitivity and rough texture — soothes and helps skin feel calmer.

What it is: A fat-soluble antioxidant.

Solves: Helps protect the formula — and your skin — from everyday oxidative stress.

What it is: A light fragrance blend.

Solves: Nothing skin-related — purely scent. If you're fragrance-sensitive, patch test first.

What it is: A naturally occurring antioxidant coenzyme.

Solves: Dullness from everyday environmental stress — helps defend skin against it.

What it is: A naturally occurring fragrance component, required to be declared as an allergen under cosmetic regulation.

Solves: Nothing directly — disclosed here because we list every allergen, not just the flattering ingredients.

WHAT'S ACTUALLY IN THE BOTTLE

30 mL. About 600 drops. Roughly 20c a day.

At two drops a day, one bottle lasts around ten months. That's the actual maths on a $59.99 bottle — not a guess, not a marketing rounding. You can check it yourself.

You'll know exactly what you bought, and exactly why.

Not a miracle claim. Not a percentage that only makes sense until you do the maths. Just a real concentration, a fully explained ingredient list, and the confidence of knowing you could defend every part of it if someone asked.

Questions, answered

GHK-Cu is naturally blue. It is also light sensitive, so the colour can gently fade over time. That is why it comes in amber glass — store it away from direct sunlight.

Many people use copper peptides and vitamin C or strong acids in separate routines — for example vitamin C in the morning and copper peptides at night. Introduce one new active at a time and patch test first.

After cleansing, apply 1–2 drops and gently rub in using circular motions, morning or night. Follow with sunscreen in the morning.

Yes. The formula is vegan, cruelty free and paraben free.

In Australia. It is distributed by Peptide Nerd from Caringbah, NSW.
