En , el periodista y especialista en medicina preventiva, James Hamblin, pone sobre la mesa soluciones duraderas y científicas. Para llegar a ellas conversó con dermatólogos, microbiólogos, alergólogos, inmunólogos, esteticistas, entusiastas de los jabones de barra y hasta con estafadores, tratando de averiguar qué significa realmente estar limpio. Y descubrió que nuestras normas de limpieza están menos relacionadas con la salud de lo que la mayoría creemos. Se ha omitido una parte importante del panorama, un ecosistema poco conocido como el microbioma de la piel: los miles de millones de microbios que viven en nuestros poros y que influyen desde el acné, el eczema y la piel seca, hasta la forma en que olemos. Este genial libro nos introduce a las bases de la nueva ciencia de la piel: cultivar un bioma saludable y adoptar el significado de «limpio» en el sentido natural. Ahora podrás hacer menos, ahorrar tiempo, dinero, energía y botellas de plástico. Keeping skin healthy is a booming industry, and yet it seems like almost no one agrees on what actually works. Confusing messages from health authorities and ineffective treatments have left many people desperate for reliable solutions. An enormous alternative industry is filling the void, selling products that are often of questionable safety and totally unknown effectiveness. In , doctor and journalist James Hamblin explores how we got here, examining the science and culture of how we care for our skin today. He talks to dermatologists, microbiologists, allergists, immunologists, aestheticians, bar-soap enthusiasts, venture capitalists, Amish people, theologians, and straight-up scam artists, trying to figure out what it really means to be clean. He even experiments with giving up showers entirely and discovers that he is not alone. Along the way, he realizes that most of our standards of cleanliness are less related to health than most people think. A major part of the picture has been missing: a little-known ecosystem known as the skin microbiome—the trillions of microbes that live on our skin and in our pores. These microbes are not dangerous; they’re more like an outer layer of skin that no one knew we had, and they influence everything from acne, eczema, and dry skin, to how we smell. The new goal of skin care will be to cultivate a healthy biome—and to embrace the meaning of “clean” in the natural sense. This can mean doing much less, saving time, money, energy, water, and plastic bottles in the process. Lucid, accessible, and deeply researched, Clean explores the ongoing, radical change in the way we think about our skin, introducing readers to the emerging science that will be at the forefront of health and wellness conversations in coming years.
