Zusammenfassung:	The present disclosure is directed to a system and device capable of predicting the in vivo SPF for a given sunscreen product without inducing sunburn on an individual. The system utilizes LEDs to measure the UVA absorbance spectrum on the skin using diffuse reflectance spectroscopy and attaches in vitro UVB aborbance spectrum to the UVA absorbance spectrum to predict the in vivo SPF of the sunscreen. La présente invention concerne un système et un dispositif capables de prédire le SPF in vivo pour un produit d'écran solaire donné sans induire de coup de soleil sur un individu. Le système utilise des DEL pour mesurer le spectre d'absorbance UVA sur la peau à l'aide d'une spectroscopie par réflectance diffuse et fixe le spectre d'absorbance UVB in vitro au spectre d'absorbance UVA pour prédire le SPF in vivo de l'écran solaire.
