HDRS300 In Vivo Spectral Characterization of Sunscreen (SPF)

New in vivo sunscreen efficacy test method developed by Bentham. 

Sunscreen manufacturers and testing laboratories can now characterize the Sun Protection Factor (SPF) of their products, in vivo, without the risk of causing erythema in test subjects. 

Based on the new HDRS (Hybrid Diffuse Reflectance Spectroscopy) technique, which combines in vitro measurements on a PMMA substrate with in vivo measurements by diffuse reflectance spectroscopy, the HDRS300 test bench has been developed to comply with the ISO 23698 standard, which will shortly replace ISO24444. 

The HDRS300 test bench, developed by Bentham in collaboration with a team of university experts specializing in SPF testing, aims to set a new standard in the measurement of in vivo spectral data. 

With high-level measurement capabilities and full hardware automation for ease of use, the HDRS300 is set to revolutionize SPF testing. 

Benefits of the HDRS300 sunscreen tester: 

• In vivo testing with excellent correlation to ISO 24444 

• Safer, no risk of erythema 

• Fully automated measurement 

• Characterization of products up to SPF 100 

• Get ahead of ISO 23698 for in vivo SPF labeling
