About
Ieso Skincare develops scientifically supported skincare aligned to community needs, not profit margins or passing trends.
Born from Research, Built for Everyone
Ieso Skincare was founded on a simple observation: dermatological research is fragmented, underfunded, and biased toward short-term commercial products rather than genuine skin health needs.
We set out to change that. By combining rigorous science with community-powered insights, we create formulations that address what your skin actually needs, backed by evidence, not hype.
Where Science Meets Community
Every Ieso formulation begins with research, not trends. We combine AI-driven skin analysis, community-validated testing, and peer-reviewed science to develop products that genuinely work.
Our decentralised community trials build one of the world’s largest open datasets of skincare interventions, ensuring our products are tested across diverse skin types, tones, and conditions.
Our Commitments
Evidence-Led
Every ingredient is selected based on clinical evidence and scientific research, never marketing trends.
Inclusive Research
We prioritise equity and diversity in our trials, building datasets that represent all skin types and tones.
Radical Transparency
Open trial data, honest ingredient lists, and no hidden fillers. We share what we know and what we don’t.
Cruelty-Free
Never tested on animals. Our community-powered approach means real-world validation from real people.
Clean Formulations
No parabens, sulphates, or unnecessary fillers. Only what your skin needs, nothing it doesn’t.
Community-Powered
Real-world data from our community trials sits alongside clinical research, so our formulations reflect how skin actually responds.
