Either unscented moisturiser or face sunscreen/spf moisturiser.

But if I had to pick out of them all the answer is probably spf moisturiser tbh

From like age 18 to when it was reformulated to sting and then discontinued I just kept buying the same spf15 Nivea tube and used it every single day even if using nothing else.

For a while dry shampoo was popular too until scent was an issue and I found out about the benzene thing
