MECHANICAL SKIN RESURFACING
An article useful for mechanical skin resurfacing techniques is suitable for transferring mechanical energy from a handheld device to skin placed in contact with the article. The article may be characterized by its Durable Abrasiveness, Compressibility, Displacement, and/or surface roughness. The article may be formed of a fibrous structure having a first major surface having associated therewith an adhesive system and a second major surface, generally opposite the first major surface. The second major surface is arranged and configured to reversibly engage a fastener of a motion-generating unit. The invention also relates to a coupling device for coupling a motorized apparatus to a disposable skin-contactable element. The coupling device includes a water-resistant first attachment and a second attachment for releasably affixing said article to a surface of the motion generation unit.
