Disclosed is a device for penetrating a skin active agent to the human body via the skin by the use of an ultrasoundapplying apparatus which applies ultrasound to the human body via the skin, comprising: (1) composition comprising: (a) safe and effective amount of the skin active agent; (b) a viscosifying agent that provides the composition of a viscosity of from about 1,000mPas to about 1,000,000mPas; (c) from about 0.1% to about 30% of a water- soluble humectant; and (d) an aqueous carrier; wherein the composition is substantially free of surfactants; and (2) the ultrasound applying apparatus comprising: (e) an application element for applying to the skin ultrasound at a frequency of from about 3MHz to about 10MHz and intensity of from about 0.1 W/cm2 to about 2W/cm2; and (f) a control element for controlling application conditions of the application element.

L'invention concerne un dispositif permettant de faire pénétrer un agent actif pour la peau dans l'organisme de l'homme, par le biais de la peau, à l'aide d'un dispositif d'applications d'ultrasons, qui applique des ultrasons à l'organisme de l'homme, par le biais de la peau. Ledit dispositif comprend : (1) une composition contenant (a) une quantité sûre et efficace d'agent actif pour la peau ; (b) un agent améliorant la viscosité, qui confère à la composition une viscosité comprise entre approximativement 1.000 mPas et approximativement 1.000.000 mPas ; (c) entre approximativement 0,1 et approximativement 30 % de substance humectante soluble dans l'eau ; et (d) un véhicule aqueux ; la composition étant sensiblement exempte de tensioactifs ; et (2) le dispositif d'application d'ultrasons comprend : (e) un élément d'application pour appliquer des ultrasons à la peau, à une fréquence comprise entre approximativement 3 MHz et approximativement 10 MHz et à une intensité comprise entre approximativement 0,1 W/cm?2¿ et approximativement 2 W/cm?2 ¿; et (f) un élément de commande pour réguler les conditions d'application de l'élément d'application.
