I'm in the UK. At the moment, I'm using a moisturiser with SPF 15 and my foundation has SPF 20 (I know that doesn't mean SPF 35 in total!)
No separate sunscreen product. Most days I'm outside for max 1-2 hours total. If I was outside for hours on a sunny day, I would use a separate factor 50 sunscreen.
I have very fair skin and am keen to protect it as much as necessary. What would you recommend? Many thanks
