Applications of Tea (Camellia sinensis) and its Active Constituents in Cosmetics

The 2019 document "Applications of Tea (Camellia sinensis) and its Active Constituents in Cosmetics" discussed the potential benefits of tea, particularly green tea, in cosmetic applications. The paper highlighted that tea contains bioactive compounds like polyphenols, catechins, and flavonoids, which have antioxidant, anti-inflammatory, and antimicrobial properties. These properties make tea a promising ingredient in skincare products, as they can help protect the skin from damage, reduce inflammation, and fight against harmful microorganisms. The document also noted the effectiveness of caffeine and green tea extract in reducing cellulite, sebum production, and improving skin and hair conditions. In terms of hair growth, external application of caffeine significantly stimulated hair follicle growth. However, the document also pointed out the lack of information on the extract preparation, its concentration, and other active ingredient content in these products. The document concluded that more research is needed to fully understand the potential of tea in cosmetics and to develop effective formulations.
