For me, 43m, white skin, not too fair, UK - I gradually tan without sunscreen (15 mins a day) deliberately in early summer (but not face or neck !) and then can use small amounts of sunscreen just on face, neck and forearms for the rest of the summer if I’m out for hours, or just nose, cheeks back of neck if it’s a short period, or maybe a wide brimmed hat with no sunscreen if possible. I like vitamin D and dislike using sunscreen and having wrinkles, so this is the compromise.

If you’re cycling a lot in strong sun, just slap the sunscreen on your face, neck and arms. Don’t get burnt.
