Systems, devices, and methods are described for providing a cosmetic device configured to deliver an active component into a skin and a method for manufacturing such a cosmetic device. In an embodiment, the cosmetic device includes an anisotropic magnetic element located in or on the head part of the body and configured to generate a magnetic field which induces diamagnetism in the active component. In an embodiment, the anisotropic magnetic element has a honeycomb magnetization pattern.

Cosmetic device for improved transdermal permeation and manufacturing method thereof

The present invention provides an electroporation device and a method for controlling an electroporation device for facilitating delivering active substances into skin such as stratum corneum while minimizing discomfort of a user by modulating applied voltage pulses. The electroporation device according to the present invention comprises: a measurement unit being configured to provide multiple outputs of one or more resistance measurement voltage pulses for measuring a resistance of skin of a user at a predetermined interval; and an output unit being configured to provide an output of one or more electroporation voltage pulses to the skin of the user based on the resistance of the skin of the user per each output of the one or more resistance measurement voltage pulses.

Electroporation device and a method for controlling an electroporation device

The present invention is directed to an aqueous dispersion comprising: (a) at least one solid wax particle having a particle size ranging from equal to or greater than 1 micron to about 100 microns and comprising at least one wax having a melting point of greater than 35&#xb0; C.; (b) a surfactant mixture comprising at least one nonionic surfactant and at least one ionic surfactant; (c) at least one volatile solvent; and (d) water.
