the thing is when you go to a higher altitude the sun's rays are more intense and oftentimes you don't feel that hot burning and there is wind associated with it as well and then the sun reflecting off the snow. so there are so many reasons why you are more likely to burn on any exposed areas when you are out there skiing. so use a higher spf product and then every time you get down to the bottom and you are waiting to go up on that lift again reapply that sunscreen. you may have to reapply it as often as every hour. i recommend using a spf 30 or higher and then also adding a mineral powder sunscreen on top of that that you can brush on and add to your protection in that way.
i love to ski and snowboard but my face gets sunburned even with sunscreen. how high of an spf do i need to wear?
