Ultraviolet (UV) radiation is the invisible killer that you can't see or smell. UV radiation can be high even in cool, overcast weather. This means that you can't rely on clear skies or high temperatures to determine when you need to protect yourself from the sun. You need to start protecting yourself from a UV index of 3 (on a scale of 12).

The UV index is communicated daily by Météo France. We also share it on our Instagram page when this is greater than 5.

We share with you a table based on a scientific study, to specify the time it takes to get a sunburn according to the UV index. Of course it also depends on your phototype (skin type).

How long does it take to get sunburned?
