The SPF Crisis: Rebuilding Trust through Science and Transparency
Interview with Chelcie Mejia, Photobiology Manager and Anna Ludwikowska, Solar Unit Manager
Eurofins
Why is there increasing discussion about an “SPF crisis” in the sunscreen industry?
Despite the well-established role of sunscreens in protecting against skin cancer, the industry is facing a growing crisis of consumer confidence. This stems from several factors, including discrepancies between labelled and actual SPF performance identified through independent testing, as well as high-profile cases involving falsified laboratory data. Together, these issues have raised concerns about the reliability of SPF claims and the credibility of existing certification systems.
What are the main factors contributing to this erosion of trust?
Consumer concerns extend beyond SPF performance alone. The discovery of contaminants such as benzene in some products, ongoing discussions about the systemic absorption of certain UV filters, and increasing environmental concerns have all fueled skepticism. In addition, social media misinformation often amplifies these issues and can encourage consumers to seek alternatives that may offer less effective sun protection.
Why is SPF claim substantiation more important than ever?
Today, substantiating SPF claims is not only a regulatory requirement but also a critical component of brand credibility. Consumers expect transparency and accuracy, and brands must be able to demonstrate that their products deliver the level of protection stated on the label. While SPF testing methods are highly standardized, variability between laboratories remains a challenge, making robust and reproducible testing strategies essential.
What challenges do brands face in ensuring reliable SPF performance?
The challenge extends across the entire value chain. Reliable SPF performance depends on factors such as raw material quality, supplier transparency, formulation consistency, and compliance with different regulatory requirements around the world. Any weakness in these areas can impact the final product and undermine consumer trust.
How can the industry rebuild consumer confidence in sunscreen products?
Rebuilding trust requires greater scientific rigor and transparency throughout the product development process. Best practices increasingly include batch-to-batch verification, early-stage in silico formulation screening, and validation through multiple independent laboratories. These approaches help improve consistency, reliability, and confidence in SPF claims.
What role do modern testing strategies play in strengthening SPF claim reliability?
Advanced testing strategies provide a more comprehensive understanding of sunscreen performance. In particular, combining in vivo and in vitro methods through hybrid testing approaches allows brands to generate more robust data and strengthen claim substantiation. This integrated approach helps ensure that SPF values are both scientifically sound and reproducible.
How does Eurofins Cosmetics & Personal Care support brands in addressing these challenges?
Eurofins Cosmetics & Personal Care offers a fully integrated approach to SPF evaluation, combining advanced testing capabilities, analytical expertise, regulatory support, and multi-site validation strategies. By leveraging a global network of laboratories and harmonized methodologies, Eurofins helps brands improve the accuracy, transparency, and reliability of their SPF claims.
Looking ahead, what will be essential for restoring consumer trust in sunscreens?
Restoring confidence will require more than simply demonstrating product efficacy. Consumers increasingly expect transparency, traceability, and integrity throughout the entire testing and development process. From formulation design and raw material selection to final claim substantiation, brands must be able to show that their products are supported by rigorous science and trustworthy data. This commitment to transparency will be key to rebuilding long-term consumer trust in the sunscreen category.
