Abstract: Tea, as a natural beverage, is highly favored due to its clear health benefits. With in-depth research on the active ingredients of tea in recent years, it has been confirmed that natural components can have positive effects on various disease models. Acne is an inflammatory skin disease with a high prevalence and recurrence rate. In addition to traditional clinical diagnosis and treatment, complementary and alternative therapies represented by patches, skin care, and dietary improvement are also popular. In the market, more and more acne control products claim to add tea active ingredients to the raw materials. Natural components such as tea polyphenols, caffeine, theanine and tea saponins have shown great potential in alleviating acne. In this paper, the effects and molecular mechanisms of different functional components of tea on inhibiting sebum secretion, alleviating acne, improving skin microbial imbalance, and alleviating skin focal inflammation were reviewed, in order to provide reference for the research and development of tea natural products.
