HDRS (Hybrid Diffuse Reflectance Spectroscopy)

A new in-vivo method for sun protection testing finally on the threshold of ISO introduction

Right from the beginning of the first ideas, Institut Dr. Schrader Hautphysiologie is part of the ALT-SPF Consortium for developing alternative methods regarding SPF determination, including the Hybrid Diffuse Reflectance Spectroscopy (HDRS) method which is currently an ISO draft standard.

Digital Measurement
Volume, Smoothness, Anti-Frizz

Digital volume measurement is used to determine hair volume following the application of hairstyling or hair care products. For this test, hair strands are treated differently depending on the type of product.

A light source is used to cast a shadow of the hair strands, which is measured digitally before and after treatment (possibly several treatments). The exact volume of the hair strand is determined by rotating the strand and further image analysis.

ICL-S (Proof of Antioxidant Efficacy)

Modern cosmetics with efficacy claims like “Anti-Ageing” or “Oxidative Protection” are among others complex mixtures of UV filters and antioxidants.

Proof of efficacy must be obtained with sound scientific methods for such claims. Sunlight (UV radiation) is the main cause of premature skin aging (photo-ageing), primarily due to generation of free radicals and the oxidative stress associated with them. The biggest challenge in claim support is non-invasive yet sensitive measurement of oxidative stress on subjects.
