Scientific evidence for skincare claims
Today's consumers expect more than cosmetic promises they expect products that are safe, pleasant to use and scientifically proven to deliver results. Whether your claims focus on anti-ageing, wellness, hydration, skin barrier support, sun protection or skin compatibility, robust scientific evidence is essential to demonstrate product performance and build confidence among consumers, retailers and regulatory stakeholders.
Normec helps cosmetic brands and manufacturers objectively substantiate efficacy, tolerability and cosmetic acceptability claims through comprehensive skin physiology testing. Combining 5 decades of scientific expertise with innovative measurement technologies and consumer-focused research, we generate reliable data that supports successful product launches and strong market positioning.
Testing of skincare products
Through a combination of instrumental measurements, expert clinical evaluations and consumer studies, we assess both the physiological effects of cosmetic products and the user experience they deliver. Our studies are tailored to support product development, regulatory requirements and marketing claims across skincare, sun care, personal care and related cosmetic categories.
