example 1

[0059] The anisotropic magnetic element according to Example 1 was prepared from a neodymium rubber magnet. The anisotropic magnetic element has a thickness of 0.5mm. The anisotropic magnetic element is magnetized to exhibit a honeycomb magnetization pattern comprising an array of a plurality of regular hexagonal magnetization regions.

example 1

[0062] Table 1 below shows detailed parameters of Example 1 (honeycomb magnetization pattern) and Comparative Example 1 (linear magnetization pattern).

[0063] Table 1: Magnetic Pattern Comparison

[0064] Example 1 Comparative example 1 Sample product area (mm 2 )

[0065] As shown in Table 1, the actual magnetized area of ​​Example 1 is 3.75 times that of Comparative Example 1. Since diamagnetic repulsion is substantially proportional to magnetic field strength, Example 1 is believed to improve percutaneous penetration.

Abstract

The present invention describes systems, devices and methods for providing cosmetic devices configured to deliver active ingredients into the skin, and methods for making such cosmetic devices. In one embodiment, the cosmetic device includes an anisotropic magnetic element positioned in or on the head portion of the body and configured to generate a magnetic field that induces diamagnetism in the active component. In one embodiment, the anisotropic magnetic element has a honeycomb magnetization pattern.

Description

technical field [0001] The present disclosure relates to a cosmetic device for improved transdermal penetration and a method of manufacturing such a cosmetic device. Background technique [0002] Some kinds of cosmetic or pharmaceutical compositions, such as skin care compositions, are intended to be applied to the skin by hand (more precisely fingers or palm) or using an applicator. The polar and hydrophilic active ingredients in the composition are designed to penetrate deep into the skin transdermally. [0003] However, transdermal penetration of polar and hydrophilic active ingredients is limited by the barrier properties of the stratum corneum (SC). Several chemical and physical penetration enhancement techniques have been explored to improve transdermal delivery of poorly permeable molecules. [0004] One candidate for active percutaneous penetration is diamagnetic. Diamagnetism usually occurs in most substances, such as water, most small organic molecules. Diamagn...
