An overview of our standard studies
Controlled application and home-in-use studies of all kinds are conducted in our Institute.. Non-invasive measurements and experts confirm your product claims for various skin parameters from tolerability and efficacy to cosmetic acceptance.
Measurements in connection with expert assessment
Digital photo documentation / Visia-CR
Studies under specialist medical supervision (dermatological, ophthalmological, dental, gynaecological)
Sensory assessments(visual, olfactory, haptic)
Perspiration odour, mouth odour, skin evenness, skin impurities,cosmetic acceptance, etc.
Application studies with users/consumers
Cosmetic acceptability and efficacy, sensory misperception (stinging test)
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.
Alternative test methods in sun protection
The internationally recognized methodology for determining the sun protection factor according to ISO 24444 is considered the "gold standard". The testing is invasive, time consuming and complex. The "Alt-SPF" project is currently the largest interlaboratory test in the field of sun protection testing and evaluates non-invasive and resource-saving alternative methods. We are participating in the review of the non-invasive in vivo methodology – HDRS (Hybrid Diffuse Reflectance Spectroscopy). The method was developed in-house, describing for the first time a reliable alternative test method for SPF and UVA-PF determination that takes into account the interaction of the sunscreen with the skin.
