Research / Science

Peptide skincare, built from the research up.

Ieso Skincare designs products around specific skin concerns. Each product starts with a question about how skin looks and feels, and with published research on the ingredients we consider. This page shows where every product stands today, including the ones that are still early.

Evidence first

We read the studies before we choose an ingredient, and we write down where the evidence is thin.

Honest about stage

Every product below is marked with its real stage. Nothing here is on sale yet.

Cosmetics, not medicines

Our products care for the look and feel of healthy skin. They are not medicines.

The Skin Science Peptide Line

Five products, each aimed at one skin concern. The bars show how far each one has come.

Stage
01

MATRIXPeptide Serum

Fine lines and firmness
Focus and research basis

The look of fine lines and skin firmness.

A blend of well-known cosmetic peptides with a stabilised form of vitamin C. We chose each ingredient after reading the published studies, and we note where the evidence is limited.

Key ingredients

Stage 2 of 5: Formulation. Stability testing and packaging checks come next.

02

RESTORECream

Barrier comfort and moisture
Focus and research basis

The look and feel of soft, comfortable, well-moisturised skin.

A balanced blend of skin-barrier lipids with niacinamide, Centella asiatica and cosmetic peptides. Some of the evidence comes from studies of single ingredients, and the lipid ratio still needs bench testing.

03

REPAIRCream

Comfort and the look of redness
Focus and research basis

The look of visible redness and a comfortable, well-cared-for skin barrier.

Ingredients chosen for skin comfort. Some of the evidence comes from studies of combination products, and we note that. We removed one early candidate ingredient after our own review of the research.

04

LUMASerum

The look of even tone
Focus and research basis

The look of uneven skin tone and dullness.

Some of these ingredients have limited human data for skin, and we consider them supporting ingredients.

05

OCULUSEye Cream

The look of the eye area
Focus and research basis

The look of fine lines and darkness around the eyes.

Peptides, caffeine and plant-derived ingredients chosen for the delicate eye area. Under-eye darkness has more than one cause, so we are only working on the type that ingredients like these might help with the look of.

Stage

Stage 1 of 5: Concept. On hold until our earlier products are further along.

How a product moves forward

Every product follows the same five stages.

1. ConceptWe define the skin concern and review the research.
2. FormulationWe draft the recipe with a US-based manufacturer.
3. Stability and safetyWe check that the product stays stable in its packaging and passes standard safety tests.
4. LaunchThe product goes on sale.
5. Post-launch efficacyAfter launch, we study how the product performs, including through research such as our GAIA study. We use what we learn to improve or change the formulation.
