The invention provides a pharmaceutical and/or cosmetic product comprising first and second active ingredient-containing formulations for topical administration to a patient, wherein said product includes storage means whereby said formulations are maintained separately prior to dispense, together with dispense means which permit said formulations to be dispensed from said storage means, characterised in that (i) an active ingredient in at least one of said formulations is contained within a polymeric delivery system (e.g. a Microsponge delivery system) and (ii) both of said formulations comprise water-based (e.g. aqueous) carrier bases having substantially the same lipophilicity. Also provided is a dual or multi-chamber dispense system suitable for dispensing said formulations which is provided with a removable closure, e.g. a cap. This closure prevents the formulations from being accidentally dispensed from a dispensing orifice(s) and can also reduce exposure of these orifice(s) to the air. The products of the invention are particularly suitable for dispensing formulations for treating dermatological conditions such as acne, in particular formulations in which the active components have stability limitations when combined, e.g. those comprising oxidising antibacterials (e.g. benzoyl peroxide) and antibiotics.
