This text investigates the complex physiological and chemical mechanisms governing the percutaneous absorption of pharmaceutical and cosmetic agents. The authors, Howard I. Maibach and Robert L. Bronaugh, synthesize decades of clinical research and laboratory data to establish a comprehensive framework for understanding how substances penetrate the skin barrier. The work provides a rigorous analysis of the variables—ranging from molecular weight to vehicle composition—that dictate the efficacy and safety of topically applied products.

Experts in the field of pharmacology and dermatology recognize this volume as a foundational reference for understanding the kinetics of skin absorption. Researchers frequently cite the text for its technical depth and its systematic approach to evaluating complex dermatological delivery systems.
