[0004] For people with dry, sensitive skin, applying cosmetics to the entire body after bathing may not be effective. It is difficult to maintain or improve the condition sufficiently, and dry and rough skin will occur repeatedly all over the body. For example, after applying cosmetics, if you sweat or get wet, the cosmetics will wash away. In some cases, the moisturizing effect was lost when the skin was wet after bathing. If you try to apply cosmetics to your whole body after wiping your skin with a towel, the time it takes to dry your skin with a towel will be When you apply the cosmetics to your skin after wiping it dry, it becomes difficult to spread the cosmetics. It takes time to spread the lotion evenly across the skin. This takes time, combined with the time it takes to spread the cosmetics on the skin, and during that time the skin begins to dry out. There was also the issue of Additionally, cosmetics with high moisturizing effects tended to feel sticky or slimy. Furthermore, even if the stickiness after application of the cosmetic product was suppressed, the cosmetic product still had a tendency to stick to the skin. People who are concerned about this want to wash off the cosmetics in the shower after applying them, but when they do, the cosmetics get on their skin. There was also the issue that the product ran off easily and did not provide the desired moisturizing effect or glossy finish after application. . [Means for solving the problem]
