Anti-Aging Hydrating Texture Brightening

Why Both

The cream isn't optional if you want the serum to work.

The single most common reason a copper peptide routine underdelivers.

Water leaves

A hyaluronic acid serum on bare skin loses most of its water to the air within minutes — and in a dry room it can pull moisture back out of your skin on the way. Something has to go over it.

Twice the peptide

GHK-Cu is in both formulas, not just the serum. Using the pair applies it twice per routine, which over eight to twelve weeks is the entire difference in exposure.

Built to layer

No silicones in either formula, and the cream's base is matched to the serum's, so it doesn't pill or ball up. That sounds minor until you've had it happen at 7am.

How to Use

Sixty seconds, twice a day.

Cleanse

Start on clean skin, still slightly damp. Damp skin gives the hyaluronic acid something to pull from.

Serum

Three to four drops. Press — don't rub — across face, under the eyes and down the neck. Wait thirty seconds.

Booster Cream

A pea-sized amount over the top, morning and night. Follow with SPF in the AM.

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 →

The Honest Timeline

What to expect, and when.

Averages, not promises. Individual results vary, and skipping nights moves everything to the right.

Night One

Comfort, not change

No sting, no tingle, nothing to build up to. If a product announces itself on application, that's usually irritation rather than efficacy.

Week 1–2

Hydration and smoothness

The first honest wins. Skin feels cushioned in the morning instead of tight, and makeup sits differently. This is surface-level and it's real.

Week 4–6

Tone starts evening out

Dullness lifts and the overall look becomes more even. Old marks fade slowly — this is the stage where people stop noticing one specific patch.

Week 8–12

Firmness, if it's coming

The appearance of firmness and fine lines is the slowest thing to shift, and the reason the guarantee runs sixty days rather than fourteen. Judge it here, not in week three.

The Guarantee

Use the whole thing. Then decide.

Copper peptides need eight to twelve weeks before you can fairly judge them, so a two-week return window would be pointless. Take sixty days. If it isn't for you, email us for a full refund — keep the empties, nothing to ship back.

Questions

About the Duo.

How long does the duo last?

Roughly ten weeks of twice-daily use. The 30 ml serum runs about eight weeks and the 50 ml cream about twelve, so most people end up reordering the serum slightly sooner.

Why buy the duo rather than the two separately?

It's the same two products for $49 instead of $59, and it clears the free-shipping threshold. Beyond price, the formulas are matched to layer — no silicones in either, so nothing pills.

Can I use just one of them at a time?

You can, but you'd be halving your GHK-Cu exposure and letting the serum evaporate. If budget is the constraint, start with the serum and use a moisturiser you already own over it.

Can I use this with retinol?

Yes, but ease into it. Alternate nights for the first few weeks — retinol one night, the duo the next. Once your skin is settled, plenty of people layer the copper peptide serum underneath their retinoid without issue.

What about vitamin C?

Keep them separated by time of day. Direct L-ascorbic acid and copper peptides don't play well in the same application, so run vitamin C in the morning and the duo at night.

Is it safe for sensitive skin?

It's formulated for it — fragrance-free, no essential oils, no denatured alcohol in either product. Patch test on the inner forearm for 24 hours first if you react easily.
