This device (1) comprises two parallel rollers (20) which are used to work theskin (3) and which are mounted in a casing (10) so as to rotate about their respectiveaxis (X-X). To treat the skin by aspiration in a reliable and effective manner,without using excessive vacuum levels, at least one of the rollers is hollow anddelimits transverse aspiration passages (64). These passages each have an outerend (641), which opens out on the periphery (20A) of the roller, and an inner end(642) which, at least when the outer end is directed towards the skin, is designedto be connected to a vacuum source via a control means (22) inside the roller. Thesepassages are distributed about the periphery of the roller in such a way that,for each position of the roller about its axis, at least one of the passages hasits outer end directed towards the skin and has its inner end in fluidic communication,via the control means, with the inner end of at least one other of the passages,of which the outer end opens out in a free volume (18, 62) defined inside the casing.
