Sun exposure is today well recognized as having an adverse effect on human skin. Part of sun radiation, ultraviolet radiation A (UVA) and B (UVB), can modify skin structures and induce short-term skin changes (sunburn, tanning, hyperkeratinization, brown spots) and long-term skin damages (accelerated skin aging and skin cancers). Protection against both UVA and UVB is very important, therefore ...

In fact, a sun exposure model predi...
