A dispenser (1) suitable for delivery of a cream, gel or soft solid composition comprising: (vi) a convex applicator surface (6) at an upper end; (vii) a replaceable cartridge (12) containing a composition to be dispensed; (viii) a passageway between the cartridge and the applicator surface; (ix) a drive mechanism for forcing the composition from the cartridge through the passageway and onto the applicator surface; and (x) an outer body (3) containing features (ii) to (iv); the drive mechanism comprising a dial unit (4) and a plunger (47), rotation of the dial unit (4) in a first direction advancing the plunger (47) axially upwards, the plunger (47) acting upon a piston seal (8) at the base of the replaceable cartridge (12), thereby forcing the contained composition upwards and outwards through the passageway and onto the applicator surface (6); rotation of the dial unit (4) in a second direction, counter to the first, rotationally re-setting the dial unit (4) relative to the plunger (47) in readiness for a further advancement of the plunger (47), rotation in the second direction not causing significant axial movement of the plunger (47).
