The formula, step by step

Your body makes its own collagen. It needs vitamin C to do it.

Here is what happens to a scoop after you swallow it, and the step in collagen formation that needs vitamin C.* That is why every scoop of ours carries 100 mg of it.

The collagen chain

Four steps from the scoop. One needs vitamin C.

Collagen isn't absorbed as collagen. Here is the sequence, and the step where vitamin C comes in.

  1. You swallow it

    Collagen is a protein, and protein is digested. The 4,500 mg of peptides in a scoop is broken down into shorter peptides and free amino acids, like any protein you eat. Nothing arrives in your skin as collagen.

  2. It circulates as raw material

    Those peptides and amino acids — glycine, proline, hydroxyproline — enter the bloodstream, like the amino acids from any protein you eat. At this point they are supply, not structure.

    Material in the blood, not collagen in the skin

  3. Your body forms its own collagen

    Collagen is made by the body's own cells, which assemble amino acids into new strands and then stabilise them. That stabilising step is enzymatic, and vitamin C is the cofactor for the enzymes that run it.*

  4. So the vitamin C is in the tub

    Every 10 g scoop carries 100 mg of vitamin C — 111% of the daily value — and 100 mg of acerola cherry, a natural source of the same. Collagen peptides and the vitamin C collagen formation needs, in one scoop.

In the tub

One scoop carries collagen and its cofactor

Ten grams once a day, stirred into coffee or whatever you drink first: 4,500 mg of marine collagen peptides, 100 mg of vitamin C and 100 mg of acerola cherry, with sodium hyaluronate, coenzyme Q10 and selenium alongside — every one at its printed dose.

Thirty scoops to a tub, which is a month, at $1.33 a day.

Every dose printed. No proprietary blend.

The ceramides

Ceramides are about half the lipids in skin's outer layer

They sit between the cells of the skin's outermost layer, alongside cholesterol and fatty acids.* Creams put them on the surface. Ours are plant ceramides you take: 840 mg a day, in two capsules.

  1. What you put onSerums, oils, moisturiser. They work at the surface and above it.
  2. The surface you seeThe outermost cells, already on their way off.
  3. The lipid layerCells set in a matrix of lipids, like brick and mortar.
  4. CeramidesAbout half of that mortar.*
Where ceramides sit in the skin.

The outer layer of skin is often described as brick and mortar: cells held in a matrix of lipids. Ceramides make up about half of those lipids.*

A cream puts ceramides on the surface, which is worth doing. A phytoceramide is a plant lipid from the same broad family, taken as a capsule as part of your diet. Ours is 840 mg of complex a day, from six plant sources, at $1.50 a day.

840 mg phytoceramide complex in two daily capsules, from oat hull fibre, spinach, sweet potato, apple, konjac root and oat straw. Vegan and gluten-free, with no wheat, soy or lactose.

Keep your serum

Neither of these replaces your serum

They're taken, not applied. Keep the routine you have — this adds to it.

Alongside, not instead

Your serum is applied. These are taken

A serum goes on the surface, and nothing here asks you to stop. A scoop or a capsule is different in kind: it's taken, like food, as part of your diet.

This is not a replacement for the routine you already have. It adds ten seconds to it.

Nothing here asks you to stop using the serum you already own.

The routine

One serving a day, no gaps

Collagen is a scoop a day, 30 to a tub. Ceramides are two capsules a day, 60 to a bottle. Both packs last a month, so the tub and the bottle run out together.

What arrives, when it runs out and how subscriptions work has a page of its own.

See what to expect

That's the mechanism. The rest is on the label.

If you'd rather just start, the Skin Duo is both: 4,500 mg of collagen peptides with 100 mg of vitamin C, and 840 mg of plant ceramides — $79.79 a month, against $84.98 bought separately.
