Navigating ISO 23675, HDRS, in vivo results and method-specific differences

Sunscreen efficacy testing is entering a period of significant methodological change. This session examines ISO 23675, ISO 23698/HDRS and established in vivo approaches — with particular attention to situations where methodologies may produce different results. Rather than simply explaining the methods, we'll address a practical question: How should R&D, testing and regulatory teams interpret conflicting evidence?

You’ll leave knowing: what method differences may mean for development, claims and interpretation of SPF data in 2027.

Erythema, pigmentation, UVA, photoaging and broader definitions of protection

Traditional SPF remains centered heavily around erythema, yet the science of photoprotection extends much further. This session explores pigmentation, UVA exposure, photoaging, darker skin tones and other biological endpoints — and asks whether the industry needs a broader framework for measuring meaningful protection.

You’ll leave knowing: which emerging endpoints may become increasingly relevant to efficacy testing and product-development decisions.

From coral testing to meaningful evidence for environmental safety

Environmental claims around sunscreen remain scientifically and commercially sensitive. This session examines what acute and chronic ecotoxicity studies, coral testing, ingredient-level data and finished-product testing can genuinely demonstrate — and where the evidence may not support the claims brands want to make.

You’ll leave knowing: what evidence teams should look for before relying on or communicating environmental safety claims.

Exposure, toxicology, endocrine concerns and the difference between hazard and risk

UV-filter safety is frequently debated in scientific, regulatory and consumer environments. This session examines systemic exposure, margins of safety, endocrine concerns, sensitisation and other toxicological evidence through a weight-of-evidence lens. The goal is not simply to ask whether an ingredient is “safe,” but to understand what the available evidence actually supports and what safety teams should be prepared to explain in 2027.

You’ll leave knowing: how to better interpret and communicate complex UV-filter safety evidence.

Heat, wear, application and the gap between tested SPF and real-world protection

Consumers do not use sunscreen under controlled laboratory conditions. Heat, sweat, application thickness, wear, reapplication and film disruption can all affect real-world performance. This session examines what happens when sunscreen leaves the lab — and whether testing and formulation approaches adequately reflect how products are actually used.

You’ll leave knowing: which real-world variables may deserve greater consideration in formulation, testing and product claims.

AI, predictive modelling, NAMs and next-generation sun-care science

AI, computational modelling and New Approach Methodologies are rapidly entering scientific discussions around cosmetic product development and safety assessment. But which tools are ready to influence decisions today? This session separates practical applications from promise — examining predictive modelling, molecular discovery, computational toxicology and animal-free approaches that could reduce development time orgenerate better evidence.

You’ll leave knowing: where these technologies can realistically support work in 2027 and whereconventional science is still essential.
