[0004] Moisturizing sprays mainly rely on moisturizing raw materials to achieve the effect of increasing skin moisture. The moisturizing ingredients are mainly water-soluble moisturizers, oily moisturizers and polymer moisturizers. Oily moisturizers are mainly used in emulsion or cream type because they are difficult to dissolve in water. In skin care products, such as vaseline, silicone oil, mineral oil, wax, etc., water-soluble moisturizers have a small molecular weight and are easily absorbed by water, but do not have long-lasting moisturizing effects, while polymer moisturizers, such as trehalose, dextran, Sodium hyaluronate, etc., have good instant moisturizing effect, but insufficient long-term moisturizing effect, and the cost of use is relatively high
