Harper's Textbook of Pediatric Dermatology, Volume 1, 4th Edition

Children´s skin is different. Maturation affects the epidermal barrier, the cutaneous microbiome, adnexal structures, vasculature, and transcutaneous absorption of drugs. The immature skin is more susceptible to pathogens and environmental disruption. Many genetic disorders are either present at birth or manifest early in childhood. Skin diseases thus present differently in children than in adults. Pediatric dermatology has seen significant advances over the last decade, particularly in the field of molecular genetics research, which has furthered our understanding of the pathogenesis of many skin diseases and the development of new approaches to treatment.
