Herbal Principles in Cosmetics: Properties and Mechanisms of Action critically examines the botanical, ethnopharmacological, phytochemical, and molecular aspects of botanical active ingredients used in cosmetics. Along with dermatological and cosmetic uses, the book also explores the toxicological aspects of these natural ingredients, maintaining a balanced view that carefully dissects the hype from the solid science.

It provides monographs complete with therapeutic properties, specific action and dermatologic properties, toxicities, pictures, and references.
