Performance of hybrid diffuse reflectance spectroscopy (<scp>HDRS</scp>‐<scp>ISO</scp> 23698) methodology for assessment of sunscreen protection in the <scp>ALT</scp>‐<scp>SPF</scp> Consortium validation study
The results showed marked improvement in the variability to a level equivalent to the reference methods while maintaining accuracy of the estimates of the protection values. Virtually all estimates were within the Prediction Intervals (PI) of the reference methods for the second study. HDRS offers the ability to accurately assess sunscreen performance for SPF, UVA-PF as well as CW without invasive damage to test subjects and offers in the future the opportunity to assess water resistance performance.
