The answer is no.
The problem with relying on the SPF in your makeup
is that you’re just not getting enough of it. You should
wear at least an SPF of 15, but an SPF of 30 is ideal.
The easiest solution is to use a moisturiser or primer
(or both!) that also contain sunscreen. It’s fine to have
sunscreen in your makeup, but consider it an added
bonus, not your main safeguard.
