Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and in particular relates to a calming and repairing composition containing composite plant ingredients and a preparation method thereof. Background Art

[0002] In modern life, people face a variety of environmental pressures and unhealthy lifestyles, leading to increasingly prominent skin problems. For example, frequent UV exposure, air pollution, cosmetic residue, and irregular sleep patterns can all contribute to a range of skin problems, including redness, sensitivity, inflammation, and dryness and dehydration. These issues not only affect the skin's appearance but can also cause uncomfortable sensations such as heat and itching, potentially compromising its health. Therefore, to address these skin problems, consumers often seek out cosmetics with soothing and repairing properties. However, most products currently on the market address only a single skin concern. For example, some focus solely on alleviating redness, while others prioritize antibacterial and anti-inflammatory properties or hydration. However, skin problems are often interconnected and complex, and single-purpose products are unlikely to fundamentally address skin health issues. Therefore, the development of a comprehensive cosmetic composition that combines redness alleviation, antibacterial and anti-inflammatory properties, and hydration and moisture retention is of significant market demand and practical significance. Summary of the Invention

[0003] The purpose of the present invention is to provide a soothing and repairing composition containing composite plant ingredients and a preparation method thereof, which solves the problem that the soothing and repairing effects of existing compositions used for preparing cosmetics are poor.
