This book delves into the science behind skincare products, offering a technical breakdown of the ingredients and formulations we encounter daily. It highlights the chemical properties that make products effective or potentially harmful, dispelling myths and misinformation commonly found online. By focusing on the chemistry and formulation processes, I aim to provide readers with a deeper understanding of what goes into these products and how they affect our skin. This book is a resource for anyone interested in the science of skincare, enabling informed, scientifically-backed decisions in a beauty industry (especially DIY) often clouded by hyped & misleading claims.
