The invention relates to medicine. The method for producing a cosmetic remedy comprises stagewise dispersion of the components at room temperature, wherein the components are introduced into an apparatus having a powerful hydroacoustic action, in which the components are dispersed and the emulsion is subjected to cavitation homogenization and then packaged. An acoustic cavitation mode is formed by a dual resonance effect within a continuous-flow mechanical oscillation system/channel of rectangular cross section in the final length, on the opposite sides of which channel sonic oscillations are generated in the parallel mode, with a standing wave being formed at the fundamental harmonic frequency for the specific channel wall, said sonic oscillations in turn forming a quasi-flat standing wave in a moving multi-phase medium, consisting of the ingredients being mixed, in the gap between the channel walls. The width of the channel gap h is selected by a multiple of one fourth of the wavelength being excited in the specific multi-phase medium by the channel walls. The oscillation amplitude of the channel wall is selected to be optimum for the various stages of preparing the emulsion and exceeds the acoustic cavitation threshold for the specific moving multi-phase medium being processed.
