寻常痤疮(acne vulgaris)是常见慢性炎症性皮肤病,广泛影响青少年及部分成年人群。咖啡作为全球消费量巨大的饮品,其对皮肤健康,尤其是痤疮的影响,正日益受到关注。研究表明, 咖啡内含的咖啡因、绿原酸等成分具有抗氧化、抗炎和调节脂质代谢等作用,可能有益于抑制痤疮的发生。此外,咖啡可能通过肠-皮肤轴调节肠道菌群,间接影响皮肤健康。然而,咖啡的摄入效果受个体差异影响显著,同时咖啡中的糖和乳制品等添加成分可能加重炎症,抵消其潜在益处。本文综述了咖啡及其主要成分对寻常痤疮的影响及可能机制,为揭示咖啡摄入及其与皮肤健康的潜在联系提供理论依据和科学指导。

Acne vulgaris is a common chronic inflammatory skin disease that affects a wide range of adolescents and some adults. As a globally consumed beverage, coffee's effects on skin health, particularly on acne vulgaris, have attracted increasing attention. Research suggests that coffee constituents, such as caffeine and chlorogenic acid, may exert beneficial effects on acne suppression through their antioxidant, anti-inflammatory, and lipid-regulatory properties. Additionally, coffee may indirectly influence skin health by modulating the gut microbiota through the gut-skin axis. However, the effects of coffee consumption are significantly influenced by individual variability, and additives such as sugar and dairy products in coffee may exacerbate inflammation, potentially counteracting its benefits. This review summarizes current evidence regarding the effects and potential mechanisms of coffee and its major components on acne vulgaris, aiming to provide a theoretical basis and scientific guidance for understanding the potential link between coffee consumption and skin health.
