Background
With the development of society, the pace of life of people is faster and faster, and the negative reactions of people to fast paced life and heavy working pressure are reflected on the health of people along with the accumulation of time, wherein the most intuitive and obvious is the skin surface, which is mainly reflected in that the skin surface becomes dry due to the loss of moisture, the skin becomes aged, wrinkles, color spots and the like appear.
In order to alleviate the negative effects of life and work pressure on the body, facial masks have become a common method of skin care for most women. The mask products on the market are various, however, most of the existing masks utilize direct absorption of the skin to nutrient solution in the mask, but the absorption effect is generally low, so that the maintenance effect of the mask is not ideal.
Research results indicate that the regeneration and repair of skin tissues can be promoted by providing an external magnetic field through an external magnetic therapy apparatus. Related products such as corresponding magnetic therapeutic apparatuses also appear in the market, but the products are relatively high in price and are not beneficial to popularization.
Research results also indicate that the magnetic nanoparticles in the facial mask can be utilized to promote the absorption of the skin on the nutrient components in the facial mask slurry by directly adding the magnetic nanoparticles into the facial mask. However, the effect is not ideal because the magnetic field generated by directly adding the magnetic nanoparticles is unstable due to disorder of the magnetic pole direction.
Therefore, the invention aims to provide the moisturizing mask which can effectively promote the skin to absorb various nutrient components and moisture in the mask.
