Collagen Peptide Serum

A peptide studied for its effect on expression lines, the ones that form where the face moves most. In a study against placebo on the other half of the face, it reduced the look of the fine lines at the outer corners of the eyes, the ones that come from movement rather than from time.

A peptide that prompts the skin to produce collagen, hyaluronic acid and the proteins that hold its structure together, and it reinforces the connections between the skin's layers. In a study against placebo on the other half of the face, deep lines at the corners of the eyes looked measurably shallower after two months.

A tripeptide that mimics the body's own signal to make collagen. In a placebo-controlled study on the ingredient, collagen density rose by 22% in four weeks, measured by ultrasound.

A collagen peptide identical to a section of the type III collagen the skin makes itself, produced by fermentation rather than taken from animals. In a randomised, double-blind study against the same formula without the peptide, the skin became denser and skin spots looked less visible.

A dipeptide the body makes itself. It works as an antioxidant and helps the skin build and strengthen the collagen that firmness and elasticity depend on.

Vegan exosomes from a green microalga, built to work like the real thing rather than harvested from animal or human cells. Exosomes are how cells talk to each other, and in a laboratory test these carried almost three times as much active ingredient into the deeper skin as conventional carriers. In a published placebo-controlled study, wrinkle depth fell by 12% and radiance rose by 20% over 56 days.

A blend of skin-identical ceramides and barrier fats. Ceramides sit in the outermost layer of the skin, where they work as the mortar between the cells: they lock moisture in and keep external stress out.

Replacing them improves hydration and supports elasticity.

Something the skin already produces. Hyaluronic acid attracts water and holds on to it, so skin feels hydrated.
