Disclosed is a device including a skin microscope for acquiring images at different wavelengths of one or more areas of a person's skin. The device includes one or more pH sensors, one or more temperature sensors, a bioimpedance sensor and a pulse oximeter included in the device so that, together with the acquisition of a skin image, it is possible to co-register the temperature, the bioimpedance and saturation of hemoglobin in the field of view of the microscope, and the pH in the immediate vicinity of that field of view. The device can be connected to an electronic device, such as a “smartphone”, for the transmission of the acquired data to the latter, possibly after they have undergone initial processing using specific algorithms.
