How strict should we be regarding the expiration dates of make-up?

Despite having what I consider to be a capsule makeup collection, I see that it’s damn near impossible to use something up because I only wear SPF and do my brows on a daily basis. However, I do need to have some eyeshadows, a couple of cheek products and some lipsticks on hand for when I need them.

I don’t want to put expired makeup on my skin but I have owned some of the things for a while. Should I strictly follow the months indicated on the packaging? Is it ok? Thoughts? What is your personal practice regarding this?
