When most people walk into a department store, drugstore, or go online to purchase skin care products, they're overwhelmed by the sheer number of choices and outlandish claims attached to them. The skin care market is a multi-billion-dollar industry where fantastic statements are made, often with little scientific rationale. In fact, it's estimated that as many as eighty percent of the over-the-counter products have no scientific data to support their assertions. In Skin Deep, author Dr. Nancy Lee Silverberg helps you make that search much easier. It discusses the ingredients that have scientific evidence-data published in peer-reviewed medical journals. She lets you know, in the simplest way possible, which products, and specifically which ingredients, are backed by data and science and which are not. Offering valuable and practical information, Silverberg, a board-certified dermatologist with more than thirty-five years of experience, helps consumers navigate the maze of skin care products available in retail stores and online. She understands you want products that do what they say and make your skin look and feel better.
