Abstract
A method, device and system for determining skin type. The method includes a step of applying at least one drop of substance onto a zone of the skin or on a collector member previously in contact with the zone of the skin. The substance can modify at least one physicochemical property of the surface of the zone or of the collector member exposed to the substance. After the drop has disappeared or been removed, the extent of the surface is evaluated and the skin type is determined as a function of this evaluation.
