Every year, nearly 80 million Americans will consult their doctors about their skin. In fact, skin disorders beat out anxiety, depression, back pain, and diabetes as the number one reason Americans see their doctors. Unfortunately, however, the vast majority will receive only a surface-level treatment, leaving the underlying conditions at the root of their skin issues unresolved. Skin doesn't lie; it reflects overall health in unimaginable ways. Dirty Looks, internationally renowned dermatologist and scientist Dr. Whitney Bowe shows readers that skin health is much more than skin deep. As a pioneering researcher on the cutting edge of the gut-brain-skin axis, she explains how the spectrum of skin disorders -- from stubborn acne and rosacea to psoriasis, eczema, and premature wrinkling -- are manifestations of irregularities rooted in the gut. Lasers, scalpels, creams, and prescription pads alone will not guarantee the consistently healthy, glowing skin we all seek. Instead, Dr. Bowe focuses on the microbiome -- where trillions of microbes "speak" to your skin via the brain -- and highlights the connection between sleep, stress, diet, gastrointestinal health, and the health of your skin. With simple explanations of the science, do-it-yourself practical skincare strategies, and a life-changing 3-week program, Dirty Looks is your roadmap to great skin from the inside out and the outside in.
