Sun protection is more than just a cosmetic promise. It plays a vital role in preventing skin cancer and premature skin ageing. As awareness of daily UV protection grows, brands and manufacturers face the increasing need to substantiate SPF claims with reliable and internationally recognised testing methods.
Dermatest has positioned itself at the forefront of this shift, offering state-of-the-art sunscreen testing aligned with the latest ISO standards without compromising on ethical responsibility.
Key features of Dermatest’s sunscreen testing
Ethical and responsible
Dermatest no longer performs SPF tests that intentionally cause skin damage to test persons. By moving away from ISO 24444 since 2022, the company sets a clear signal: product verification should never come at the expense of a test persons safety.
Advanced ISO methods
- ISO 23675:2024: Purely in vitro SPF determination on PMMA plates; fast, cost-efficient, and highly reproducible.
- ISO 23698:2024: A hybrid HDRS method (in vitro + in vivo) that measures SPF, UVA-PF, and Critical Wavelength – non-invasive and ideal for premium and comprehensive product claims.
- ISO 24443:2021: Established in vitro test for UVA protection, complementing SPF assessments for a complete UV spectrum analysis and can be combined with ISO 23675:2024.
Flexible screening options
For products still in development, Dermatest offers preliminary screenings that provide an early SPF estimate. These can be extended into full tests to support official product labelling.
Why this matters for brands, manufacturers and consumers
Reliable SPF testing ensures that sunscreens and daily-use skincare products deliver the UV protection they promise across both the UVB and UVA spectrum. This is essential for long-term skin health and strengthens consumer trust in brands.
By adopting methods that are precise, non-invasive, and ethical, Dermatest provides manufacturers with robust data for regulatory compliance while also reinforcing a shared responsibility for skin health.
