Field of the Invention The present invention relates to an intensive care device for skin which is used for intensive care of the skin easily and cleanly. 2. Description of the Related Art Conventionally, various cosmetics such as lotion, milky lotion, cream, and serum have been applied to the skin in order to impart various effects to the skin, such as beautiful skin, anti-aging, and whitening. Have been done. However, when intensively taking care of local problems such as acne and spots, it is difficult to apply a large amount of low-viscosity, highly fluid cosmetics to the skin,
Some long-term continuous use is required. [0003] In order to apply the cosmetic intensively to a local site where acne, stains, etc. have occurred, gauze or absorbent cotton impregnated with the cosmetic is applied to the site such as the face, and the like. Trying to get the effect is done. [0004] However, the above-mentioned method must be kept stationary during the application so that gauze and cotton wool do not fall off, and cannot be performed during a busy time. It had the following. Also,
In the case of using gauze or absorbent cotton, there is a problem that the entire amount of the cosmetic to be impregnated is not retained by the gauze or absorbent cotton and flows outside to stain clothes and the like. Furthermore, simply impregnating gauze or absorbent cotton with cosmetics causes water to evaporate immediately from the surface, which is not always satisfactory in moisturizing action on the skin. In addition, fiber waste of gauze and absorbent cotton tends to remain on the surface of the face and the like, and after care is completed, it is necessary to check the residual fiber waste on the face and the like with a mirror. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has an excellent skin care effect with moderate retention and breathability of cosmetics, and adheres fiber debris and the like to the skin.
