Skin brightening cosmetic material and cosmetic compositions containing a mixed extract as an active ingredient, and methods for their manufacture

Skin Brightening Cosmetic Technology Using a Mixed Extract of Poria cocos, Soybean, Licorice, and Citrus unshiu Peel

This technology relates to a skin brightening cosmetic material and cosmetic composition containing a mixed extract of Poria cocos, soybean, licorice, and citrus unshiu peel as an active ingredient. Specifically, it is a cosmetic composition and manufacturing technology that regulates melanin formation and skin tone changes using a plant-based mixed extract.

Existing skin brightening cosmetics often rely on specific ingredients or have limitations in sufficiently achieving desired effects such as overall skin tone improvement, hyperpigmentation relief, and reduction of yellow undertones. This technology proposes a method of applying an extract, obtained by mixing Poria cocos, soybean, licorice, and citrus unshiu peel in specific weight ratios, followed by ethanol extraction, concentration, and freeze-drying, to skin toner and cream compositions.

Accordingly, this technology is expected to inhibit melanocyte growth, melanin formation, tyrosinase activity, and related gene expression, making it valuable for use in functional cosmetics, skin tone improvement products, and the natural product-based beauty material industry.
