Research Summary: We are honored to present to the readers the book entitled *Carrier-Mediated Dermal Delivery: Applications in the Prevention and Treatment of Skin Disorders*, which is based on the systematic revision of the most recent findings. This book contains several contributions on new approaches for the management of skin aging and photocarcinogenesis, as well as topical formulations based on nanocarrier systems for skin disorders. These chapters discuss the structure and skin morphology in detail. Cosmeceuticals, laser and photodynamic therapy, and melatonin-based treatments are presented as important strategies for photoaging management. Photodynamic therapy and melatonin can also be used in...

Research Summary: It has been recognized that the vehicle in which a permeant is applied to the skin has a distinctive effect on the dermal and transdermal delivery of active ingredients. The cutaneous and percutaneous absorptions can be enhanced, for example, by an increase in thermodynamic activity, supersaturation, and penetration modifiers. Furthermore, dermal and transdermal delivery can be influenced by the interactions that may occur between the vehicle and the skin on the one hand, and interactions between the active ingredient and the skin on the other hand.Emulsions are widely used as cosmetic and pharmaceutical formulations because of their excellent...
