System for analysing the physico-chemical properties of a skin surface

A system for analyzing physico-chemical properties of a skin surface, the system comprising:

• at least one contact sensor configured to be applied to said skin surface to be analyzed in order to determine a dielectric constant by measuring capacitance variation between the air and the skin surface, once or twice a day, relating to a particular area of the skin surface,
• at least one environment sensor designed to accompany a user throughout the day and to measure, throughout the day, at least one external parameter acting on said skin surface,
• a processing unit interfaced with the contact and environment sensors, said processing unit comprising a module that, responsive to receiving control signals, analyzes physico-chemical properties of the skin surface, the control signals including signals that cause:
• (i) the at least one contact sensor to take one-off measurements, wherein the one-off measurements are carried out in response to an indication from the user with non-predictable and variable time intervals,
• (ii) the at least one environment sensor to take over time measurements,
• (iii) the processing unit to receive and analyze a first signal representative of the one-off measurements and a second signal representative of the over time measurements to generate an analysis of the physico-chemical properties of the skin surface,
• (iv) the processing unit to diagnose, based on the analysis of the physico-chemical properties of the skin surface, a skin condition of the skin surface, wherein the skin condition includes at least a hydration level of the skin surface, the hydration level representative of a proportion of water on the skin surface and determined according to the dielectric constant, and
• (v) the processing unit to determine, based on the diagnosis of the skin condition of the skin surface, a suitable treatment.
