Coffee and skin: What do we know about it?

Abstract

Coffee is one of the world's most popular drinks. It is only an inspirational morning refreshment for some, but for others it has become a lifestyle beverage with a global consumption of billions cups per day. Because of its popularity, coffee has often been proposed to be able to prevent health problems and has attracted a great deal of research over the years. Although there has been limited research evaluating the effectiveness of coffee in ameliorating certain health conditions, there is a compelling evidence that coffee consumption has potential benefits for a variety of chronic diseases. Recent studies have confirmed that moderate amount of coffee consumption might have a role in protection against type 2 diabetes, metabolic syndrome, Parkinson's disease, Alzheimer's disease, depression, cognitive impairment, chronic liver disease, chronic kidney disease, prostate cancer, endometrial cancer, liver cancer, leukemia and cardiovascular diseases, including hypertension, coronary heart disease and venous thromboembolism. In dermatological point of view, currently there is a growing body of evidence suggesting that caffeine and other nutrients contained in coffee may protect against melanoma and non-melanoma skin cancer. Moreover, as the new data on coffee and health continues to get emerged, it is getting clear that coffee is also effective in inflammatory disease prevention, including inflammatory skin diseases. In this review, we focused on recent evidence about coffee and dermatological diseases and aimed to explore the link between coffee and melanoma/ non-melanoma skin cancers, psoriasis and rosacea.
