Problems solved by technology

However, the single macromolecular component in these products can only make the product have film-forming properties, but cannot achieve the effect of slow-release small molecule moisturizers
Small molecule moisturizers such as trehalose and sodium pyrrolidone carboxylate quickly penetrate the stratum corneum and are absorbed by the skin. They cannot exert their moisturizing effect in the stratum corneum for a long time, and the skin cannot be continuously supplemented by small molecule moisturizers, so it cannot achieve long-term maintenance. effective moisturizing effect

Description

technical field [0001] The invention relates to the field of skin care products, in particular to a cream with moisturizing effect and a preparation method thereof. Background technique [0002] Creams are an important part of people's daily skin care products, and moisturizing has always been an important claim in cream products. Most moisturizing creams achieve moisturizing effect by maintaining moisture in the stratum corneum, maintaining skin elasticity, and promoting the repair of skin barrier function. Whether the moisturizing effect of moisturizing cream is long-lasting and long-lasting has always been an important issue that people pay attention to. [0003] The moisturizing function of the moisturizing creams currently on the market is mainly reflected in two aspects: first, the water phase of the cream provides water-soluble moisturizing ingredients, such as glycerin, urea, etc.; A moisturizing film is formed on the surface to reduce water loss in the epidermis o...
