Depending on who you listen to, the secret to beautiful skin is microbiomes. Or Korean rice water. Or maybe a dermaplaning tool. It feels like you need a degree in chemistry to even understand what these products are, and if they live up to the hype. Luckily, Victoria Fu and Gloria Lu, professional skincare chemists have done that work so you don’t have to. The science may seem complicated, but this book will show you how simple it can be, giving you what you need to make informed decisions about your skin (and your wallet). Skincare Actives? Technically, cat sneezes could count. SPF? Yep, super important. Caffeine serums? The science is still out. CBD additives? Not enough studies yet, so the jury’s still out. The authors are the creators behind the popular Chemist Confessions Instagram, and this book brings the sass, humor, and solid inLayoution they’re known for. Additional chapters address the best ingredients for every skin type, and reveal the only four products you really need.
