Description

Technical Field

[0001] The invention relates to a roller microneedle kit. Background Art

[0002] With the change of the pace of life, more and more people pay attention to the maintenance of beauty and health. Among them, ladies pay more attention to it, especially in skin care, and skin care is nothing more than whitening, wrinkle removal, freckle removal and scar removal and other aspects.

[0003] At present, the skin care products available on the market generally apply beauty serum or apply facial mask. The beauty care effects of these two methods are not significant and the effects come slowly. Moreover, all kinds of nutrient solution skin care products only stay on the surface of the skin and are difficult for the skin to absorb. There are several technologies that can be directly absorbed by the skin. One of them is microneedle beauty technology, which infuses nutrients into the skin through the contact between microneedles and the skin. During the infusion process, it is difficult to control the nutrient solution on the microneedles. The thread beauty claimed on the market is just a decoration and does not play any role. Moreover, most of the threads are made of silk waste. Not only do they have no good effects, but they also have side effects and damage the skin when used on the skin. Another one is radar thread carving, which uses ultrasound to beautify the skin. Ultrasound can indeed act on the skin cells quickly and effectively to beautify the skin, but ultrasound is difficult to control. It will also kill good cells while using it, causing certain damage to the skin.

[0004] Meanwhile, traditional microneedles are made of metal materials and through traditional processes. In the past 10 years, most of the microneedle arrays and microneedle sheets that have appeared on the market are made of new technologies. The new technology uses ultra-micro technology, and the materials are single crystal silicon, medical alloys, polymer materials, etc. to make new microneedles with relatively small sizes. It is widely used in the beauty industry, and is combined with cosmetic liquid products or medical liquid products, achieving good social and economic benefits. Summary of the invention
