Que signifie le SPF dans une crème solaire ?<end_of_turn>
<start_of_turn>model
SPF in sunscreen is an acronym for "Sun Protection Factor". A sunscreen's ability to shield skin against the damaging effects of ultraviolet (UV) B radiation from the sun is measured by its SPF. It displays the level of sunburn protection. The degree of sunburn protection offered by the sunscreen increases with the SPF number. 
It's crucial to remember that SPF does not accurately reflect protection against UVA rays, which also cause skin damage, and instead measures protection against UVB rays, which are the main cause of sunburn. Therefore, for complete sun protection, broad-spectrum sunscreens that block UVA and UVB rays are advised.
