That's where we come in. As you begin your skin-care quest, we hope to answer here in this skin-care many guides book as many of your questions as we can-with the help of research and experts rather than hype. Open this book to learn more about the actual elements in a skin-care routine and an overview of active ingredients that work best for certain skin conditions. We also have specific sections for skin of color, what to do if you're pregnant, and what to keep in mind if you have a diagnosed condition that affects your skin.
