Apparatus comprising an array of individually controlled skin treatment units to be applied to a skin segment with each of the units comprising: a housing defining a cavity that fluidly communicates with a source of vacuum pressure, having an inner side terminated by a rim facilitating sealing of the cavity when the unit is applied to the skin, dimensions of the cavity being sufficient to accommodate a volume of a skin segment drawn into the cavity by the source of vacuum pressure to create a skin protrusion wherein application and release of vacuum pressure to the unit generates a back and forth massaging movement of at least a portion of a volume of skin against the rim, and wherein each of the units of the array has at least two degrees of rotational movement with respect to an adjacent unit so that the array can conform to skin segment topography.
