Complete the system with the Duo
The serum needs something over it to stop it evaporating. The Booster Cream is formulated to layer on top without pilling — and it carries a second dose of GHK-Cu. Buying both as the Duo saves you $10.

What It Does
Where the serum earns its place.
Surface results first, structural results later. That order is worth knowing before you start.
TEXTURE
The first thing you'll notice
Rough patches and the grainy feel across the cheeks. It's a surface-level change, which is why it shows up early — usually in how your makeup sits before you see it in the mirror.
HYDRATION
Three weights of HA
Low, mid and high molecular weights hydrate at different depths of the surface. Apply on damp skin so there's water available for them to hold onto.
FIRMNESS
The long game
Anything to do with the appearance of firmness and fine lines takes eight to twelve weeks of consistent use. That's why the guarantee runs sixty days rather than fourteen.
How to Use
Three to four drops, twice a day.
01
On damp skin
Straight after cleansing, before skin dries down. The hyaluronic acid needs water to work with.
02
Press, don't rub
Three to four drops across face, under the eyes and down the neck. Pressing wastes less than dragging.
03
Seal it in
Wait thirty seconds, then moisturiser. SPF over the top in the morning.
Layering: run vitamin C in the AM and this in the PM. Retinol is fine on alternate nights while you settle in. Full layering guide →

Questions
About the serum.
Do I need a moisturiser over it?
Yes. A water-based serum evaporates off the surface without something over it, and you lose most of what you just applied. Any moisturiser works — the Booster Cream is simply formulated to layer over this one without pilling, and adds a second dose of GHK-Cu.
How many drops, and how long will it last?
Three to four drops per application. At twice daily, a 30 ml bottle runs about eight weeks — which lines up neatly with the point where firmness results become fair to judge.
Will it pill under makeup?
It shouldn't — there are no silicones or film-formers in it. If you get pilling, it's almost always a product further up the stack, or not waiting the thirty seconds before the next layer.
Can I use it around my eyes?
Yes. Press it along the orbital bone rather than right up to the lash line. Avoid getting it in the eye itself.
Why is it blue?
That's the copper-peptide complex, not dye. A copper peptide serum that's completely clear is worth asking questions about. It won't stain skin or bedding.
Is it pregnancy-friendly?
There's no retinoid, no salicylic acid and no fragrance in it, which is why people often move to peptides during pregnancy. That said, we're a skincare brand, not your clinician — run it past your OB or midwife first.
Better together
Both steps, $10 less.
The serum delivers the peptide. The cream keeps it there. The Duo is the same two products, priced as one.
