For me this VICHY Protective Sun-Cream with SPF 25 is ideal. You also need to take special care of your eye area, which is more gentle. For that I used the VICHY stick for sensible zones with SPF 50.
It has a very convenient stick form and can be applied really easily.
With all that protection you can enjoy a carefree sledging. YUHUUUUUUUUUUUUUUUUUUU!!!!
