N1 - Funding Information:
Ana Maria de Lauro Castrucci graduated in Biology and got her Master and PhD degrees in Physiology at the University of Sao Paulo. Her post doctorate was made under the supervision of Prof Mac Eugene Hadley, at the University of Arizona, during the 80’s. In 1999, she took a sabbatical leave of one year as a visiting scholar at the Uniformed Services University of the Health Sciences, Maryland. Since 2005 she has collaborated with the University of Virginia. She retired in 2001 from the University of São Paulo as Full Professor of Physiology, but kept her laboratory as Senior Professor, since then. She is a member of the Brazilian Academy of Sciences and of The Academy of Sciences of the State of São Paulo and received the National Order of Scientific Merit awarded by the President of Brazil. She presently holds research grants from the São Paulo Research Foundation, FAPESP, focusing the following subjects: clock genes, opsins, light, temperature, endocrines and signaling mechanisms in crustaceans, fish, amphibians, birds and mammals.

N2 - The consensus on the effects of excessive sun exposure on human health has long emphasized the negative effects of solar UV radiation. Nevertheless, although UV radiation has been demonized, less is known about the consequences of sun exposure while using sunscreen, which can lead to high visible light exposure. UV and visible light play key roles in vitamin D synthesis, reduction of blood pressure, among other beneficial effects. In this review, we aim to provide a comprehensive view of the wide range of responses of the human skin to sunlight by revisiting data on the beneficial and harmful effects of UV and visible light. We start by exploring the interaction of photons in the skin at several levels including physical (depth of photon penetration), chemical (light absorption and subsequent photochemical events), and biological (how cells and tissues respond). Skin responses to sun exposure can only be comprehensively understood through a consideration of the light-absorbing molecules present in the skin, especially the light-sensing proteins called opsins. Indeed, many of the cellular responses to sun exposure are modulated by opsins, which act as the “eyes of the skin”.
