Summary This book explores various topics relevant to understanding the complexities of biological effects generated by solar radiation. Solar-energy-absorbing substances are evaluated, including sunscreen agents, and their influence on cancers and diseases. One assumption is the use of sunscreen agents cannot prevent the photoinitiation of biological system malfunction, such as immunosuppression. On the contrary, sunscreens can help enhance the negative solar-energy-induced effects, such as by skin penetration. This collection offers critical appraisals of clinical studies involving vitamins and nons
