Skin functionality

Skin Functionality: A Cosmetology Perspective presents a comprehensive examination of the skin as a multifunctional biological organ from the viewpoint of cosmetic science. Moving beyond a purely anatomical approach, the book explores the skin’s major physiological functions, including barrier protection, immune defense, thermoregulation, sensory perception, exocrine activity, water and electrolyte balance, and social signaling. By integrating dermatological knowledge with cosmetological applications, the book provides a practical framework for understanding how skin functionality influences cosmetic formulation, product development, ingredient selection, and skincare strategies. Designed for cosmetologists, cosmetic scientists, formulators, skincare professionals, students, and researchers, this work aims to bridge the gap between skin biology and cosmetic practice. The book promotes a function-centered understanding of the skin and highlights the importance of physiological literacy in the development and evaluation of modern cosmetic products.
