This device may include two parallel rollers which work the skin and which are mounted in a casing so as to rotate about their respective axis. To reliably and effectively treat skin by aspiration, without using excessive vacuum levels, at least one of the rollers may be hollow and delimit transverse aspiration passages. These passages may have an outer end, which opens out on the periphery of the roller, and an inner end which, when the outer end is directed towards the skin, is connected to a vacuum source via a control means inside the roller. These passages may be distributed about the periphery of the roller such that, for each position of the roller, at least one passage has its outer end directed towards the skin and its inner end in fluidic communication, via the control means, with the inner end of at least one other of the passages.
