A liquid antimicrobial composition is provided for use in the disinfection of the skin of a human or an animal, in particular where disinfection of a drug resistant organism is required. The composition comprises a cationic, cell membrane-disrupting biocide and a cationic dendrimer capable of inhibiting an efflux pump mechanism of said cell membrane. The cationic, cell membrane-disrupting biocide is preferably any or a combination of chlorhexidine, a polymeric biguanide, octenidine dihydrochloride and a quaternary ammonium compound. The dendrimer is provided to bind and disrupt the cell membranes of microorganisms in order to inhibit or destroy the cell's efflux pump mechanism thereby preventing microorganism strains resistant to the cationic membrane-disrupting biocide from becoming prevalent, particularly if the biocide comprises chlorhexidine. The dendrimer is preferably a G-0 to G-3 dendrimer comprising any or a combination of quaternary ammonium functionalised poly(propylene imine), polylysine, dendrimers with surface groups based on a sugar and polyamide amine (PAMAM) dendrimers. The composition is preferably in the form of an aqueous or aqueous alcohol solution, dispersion or emulsion that may have been adsorbed by a wipe.

The invention relates to the use of a polylysine dendrimer or a salt thereof for the management of blemish- or acne-prone skin or for treating or preventing acne vulgaris. The polylysine dendrimer is used as an active for restoring or rebalancing skin microbiota. The polylysine dendrimer is also used as an active for improving or restoring the aspect and the feel of the skin to be treated.
