Description

Technical Field

[0001] The invention belongs to the technical field of rare earth material application, and in particular relates to an antioxidant and anti-ultraviolet care composition and a preparation method thereof. Background Art

[0002] As people pay more and more attention to skin health, the demand for antioxidant and UV protection care products is also growing, and they are gradually becoming an important part of the skin care field. However, although existing care products have antioxidant and UV protection effects to a certain extent, they still have many shortcomings. Specifically, these products generally have problems such as insufficient antioxidant performance, poor UV protection effect, and poor use experience. These problems not only affect consumers' experience, but also limit the potential of care products in protecting skin health.

[0003] In terms of anti-oxidation, many existing products cannot effectively neutralize free radicals and cannot meet the high standards of skin's anti-oxidation needs in daily life. In terms of UV protection, some products have limited UV protection capabilities and cannot provide comprehensive and lasting protection for the skin. In addition, the texture and formula design of some care products are not reasonable, resulting in poor skin feel during use, which may appear greasy, heavy or difficult to absorb, thus affecting consumers' willingness to use.

[0004] Therefore, it is particularly important to develop a high-quality skin care product with good antioxidant and UV protection effects. This product not only needs to perform well in antioxidant and UV protection, but also has a comfortable feel to use to meet consumers' diverse needs for skin care. Summary of the invention
