1. A skincare device, comprising:
a brushhead including a marking disposed on a surface of the brushhead, the marking including a shape, a color, and a height, the height defined by a difference between a surface of the marking and the surface of the brushhead upon which the marking is disposed, the surface of the marking being parallel to the surface of the brushhead;
a body including a motor assembly configured to oscillate the brushhead; and
a first optical encoder configured to
detect the marking shape and color and determine the height of the marking based on a focal distance between the first optical encoder and the surface of the marking, and
determine an identity of the brushhead based on (i) the detected marking shape, (ii) the detected marking color, and (iii) the determined marking height.
