Supporting research and innovation
Nevisense is increasingly used in academic studies focused on skin health, barrier function and the effects of dermatological treatments. Research groups value its repeatability, non-invasiveness and quantitative data output.
Used by leading institutions
Hospitals, dermatology clinics and research centers in Germany, the US and other countries have integrated Nevisense into their workflows – citing improved diagnostic decision-making and streamlined patient care.
Validated in the largest study of its kind
The clinical performance of Nevisense was validated in a pivotal prospective study involving 1,951 patients and 265 melanomas—the largest study of its kind conducted in melanoma detection. The study demonstrated 97% sensitivity and a 99% negative predictive value, providing robust evidence for the use of Nevisense as an adjunct to clinical and dermoscopic evaluation.
