Abstract:
During usual daily activities, an appropriate protection against solar UV exposure should prevent clinical, cellular and molecular changes potentially leading to photoaging. In skin areas regularly exposed to sun, UV-damage is superimposed to tissue degeneration resulting from chronological aging. It is, therefore, important to know if moisturizers and daily-care products containing UVA absorbers combined with UVB ones are able to prevent these skin damages. This review will summarize clinical studies evaluating this topic. These studies demonstrate that broad-spectrum protection in moisturizers or daily-care products can prevent the "silent" sub-erythemal cumulative effects of UVR from inadvertent sun exposure.

Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
