New SPF-meter HDRS


The number and quality of topical applied SPF products has improved considerably over the past three decades. Our skin is the best substrate for SPF-measurement but measuring transmission in vivo is not possible. C+K´s new approach: SPF determination via hybrid diffuse reflectance spectroscopy (HDRS). Advantages: • Non-invasive technology – more ethical • Low effective UV-dose < 1/5 MED with UVB • Extremely low UV-Dose for HDRS < 1/50 MED without UVB • Compact, easy-to handle • Adjustable LED spectrum • Simple and safe application with convenient user software • SPF determination using additional in vitro spectrum (Hybrid) • Extremely time saving: about 1 hour (compared to 24h for ISO 24444) • Cost-saving
