Do the sensible thing and wear sunscreen with a broad spectrum UVA and UVB of 30+ SPF. Your future self will thank you for it.
Our favouite is Banana Boat - Sport SPF 30. It stays on, and if applied correctly it doesn't cause stinging to eyes with sweat. It's water proof and splash proof. We've never been burnt or had any signs of skin damage to the face when used in extreme heat and UV index of 10+.
