The skin functions as a complex organ that protects, senses, and regulates, making its structure and physiology vital to aesthetic practice. This book presents the microscopic and functional aspects of the skin, covering epidermal layers, dermal components, appendages, vasculature, and nerve supply. It explains cellular turnover, barrier function, pigmentation, and responses to injury. Histological changes associated with aging and common dermatologic conditions are explored. Diagrams, tissue slides, and clinical correlations help readers understand how structure impacts appearance and treatment response in cosmetic procedures.
Kgomotso Letsoalo brings deep insight into skin structure and function, grounded in her academic training in physiology and histology. She has taught at leading universities and mentored emerging researchers in the biomedical sciences. Her published work often centers on the microanatomy of the skin and its implications in aging and repair. She has served in editorial roles for journals and reference materials in skin science. Her scholarly interests extend to barrier integrity, wound healing mechanisms, and the cellular basis of dermal therapies.
