The present invention relates to a device (10) for the topical application of cosmetic substances. An apparatus (10) for topical application of a cosmetic substance comprises a measuring device configured to measure the skin properties of a human or animal subject, and a human or animal test depending on the measured skin properties. And an actuating device configured to change the permeability of the skin of the body. The device (10) for topical application of a cosmetic substance is such that substantially no iontophoretic current flows through the skin and the cosmetic substance is applied to the skin after the skin permeability has changed. The coating apparatus further comprised is further provided. [Selection] Figure 1本発明は、美容用物質の局所適用のための装置(10)に関する。美容用物質の局所適用のための装置(10)は、ヒト又は動物被験体の皮膚の特性を測定するように構成された測定装置と、測定された皮膚の特性に応じて、ヒト又は動物被験体の皮膚の浸透性を変化させるように構成された作動装置とを備える。美容用物質の局所適用のための装置(10)は、実質的に、イオントフォレシス電流が皮膚を通って流れず、皮膚の浸透性が変化した後に、皮膚に美容用物質を塗布するように構成された塗布装置を、さらに備える。【選択図】図1
