Bobbi Brown Face Base

[YaYaSweet]

I’m not sure when to use the face base. Do I use in after my serums as a moisturizer or do I use it after my sunscreen as a primer? 
Can I use it as a moisturizer and use something else as a primer?

Do I use it as a moisturizer then sunscreen then use it again as a primer?  This product has me so confused!

@YaYaSweet @I use it like a moisturizer, so after my serums but before my sunscreen. Then I use a different primer.
