The present invention relates to a topical skin-care preparation in the form of an ointment containing mupirocin and betamethasone dipropionate as active principles and a carrier formulated with all or some of the following components: hydrogenated castor oil, polyethylene glycols and preservatives. The inventive preparation is advantageous over prior art compositions in that it has a specific therapeutic effect on primary and secondary skin infections, such as relief of pruritic inflammatory manifestations of dermatosis, a wide range of activity against the majority of bacterial species involved in skin infections, and a high level of activity against Staphylococcus and Streptococcus, including multi-resistant strains. In addition, the therapeutic effect of the preparation is not affected by the size of the inoculum and the preparation has no sensitization potential, thereby providing the product with an excellent safety profile for use by the patient. Moreover, the preparation can counteract the possible secondary effects of one of the components with the effect of another.
