DEVICE FOR DERMATOLOGICAL USE WITH A FAILSAFE CONTROL

摘要

A device and method for dermatological use with one or a plurality of active components and a failsafe control. The device includes a light source configured to be toggled between an activated state and an inactivated state, a photosensitive detector configured to detect incoming light and a processing unit for the failsafe control. The processing unit is configured to concurrently determine whether light detected by the photosensitive detector is indicative of a safe operating proximity and is indicative of a safe operating skin tonal range; and activate the active components only when the processing unit determines that the device is within the safe operating proximity, and that the light reflected from the surface is indicative of the safe operating proximity and safe operating skin tonal range.
