New SPF-meter HDRS
Technology & Engineering
Information
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
