The perceived visual appearance of skin such as axilla skin, as indicated by tone, radiance and/or smoothness, is improved significantly by topical application of an antiperspirant composition that is a roll-on emulsion that comprises a dihydric or trihydric humectant and/or a glyceride oil. and a mica pigment, The visual appearance can be further enhanced by incorporating into the composition a particulate microfine aluminium oxide and/or a silicone elastomer. The mica-containing compositions are advantageously applied from a roll-ball dispenser in which the depth of film of fluid on the rolling ball is controlled, such as by a spider spaced inward of the ball and/or the flow of fluid within the ball housing is perturbed such as by a castellated sealing ring and/or a shallow bead outward of the sealing ring within the ball housing.
