Setting powder and baking

Hi,

If you’re trying to do a full glam for longer lasting hours, should u set your undereye first (I have charlotte tillbury airbrush powder) and then bake on top of it? (Huda beauty poundcake) or I should just use only one of it? i have combination skintone. I always used to do both but I just learnt the difference between the two and realized I may have been going wrong somewhere. I like to get that brightening effect.
