Our Efficacy Testing
We commissioned independent laboratory testing on human skin to measure how our formulations protect against UV-A damage and urban pollution. Here's what the science revealed, visualised through microscopy imagery.
Beneath the Surface
These are photographs of real human skin samples, taken under the microscope in the lab. Nothing has been generated or retouched. We publish them alongside the method, so you can see exactly what we measured.
How to read them:
- Red shows oxidative damage to the skin’s proteins. Less red means less damage.
- Yellow shows Collagen I, the protein behind firmness. More yellow means more collagen protected.
- Turquoise marks the cell nuclei, so you can see the layers of the skin.
- In each pair, untreated skin is on the left and treated skin on the right.
Peptide Longevity Serum, applied after UV-A stress
Carbonylation (red staining)
BEFORE: Shows the visible effects of UVA stress on the skin’s protein network.
AFTER: Treatment reduced protein damage up to 95%
Collagen I (yellow staining)
BEFORE: Collagen levels before UVA stress.
AFTER: Treatment reduced oxidative damage to collagen I by 91%, helping preserve the skin’s structural protein network.
Tripeptide Antioxidant Day Cream, applied before pollution and UV-A stress
Carbonylation (red staining)
BEFORE: Skin exposed to UV-A and pollution shows increased oxidative protein.
AFTER: 100% efficacy represents restoration of protein levels.
Collagen I (yellow staining)
BEFORE: Collagen I damage from UV-A and pollution.
AFTER: Collagen I preservation increased by 64% compared with untreated stressed skin.
Presented at ESDR 2026
In September 2026 we presented our research at the 55th Annual Meeting of the European Society for Dermatological Research in Heidelberg, where dermatologists and skin scientists share new findings. The abstract is published in the Journal of Investigative Dermatology.
The poster sets out the full study, carried out with OxiProteomics on donated human skin. It shows how the Tripeptide Antioxidant Day Cream protected the skin’s proteins before UV-A and pollution stress, and how the Peptide Longevity Serum helped repair them afterwards. The images, methods and results are all there to read.
