Best primer for 40 year old skin?

Hi all. I have the skincare part down, but I do live in humid and hot weather. And my skincare journey is also about a 5 weeks in. I’m looking for something that will Keep my makeup in place for a special occasion that is going to last at least four hours.

What has been great for you? I have combination skin and will sweat like crazy right in my tzone. I use huda beauty powder and CT spray.

Thank you so much for any and all help.
