[0002] With the development of society, people's demands for skin care products, especially facial masks, are becoming more and more diversified. They must provide immediate hydration and soothing, as well as long-term skin improvement effects. The ways of use are also becoming more and more diverse, with masks made of different materials and shapes, as well as many facial masks with different textures.

[0003] However, cream masks that can soothe and repair, intensively moisturize, and deeply cleanse the skin are relatively rare; water-based and oil-based agents lock in the freshness of water-soluble active ingredients and oil-soluble active ingredients respectively, and at the same time enhance the user's sense of ritual and participation in the skin care process. It is an innovative dosage form that combines various needs. Summary of the invention

[0004] In order to overcome the above problems, the present invention aims to propose a two-in-one skin care mask and a preparation method thereof, with the aim of solving the problem in the prior art that it is impossible to achieve a cream mask that can both soothe and repair, intensively moisturize, and deeply cleanse the skin.
