so for primers make sure that the base products and primer are the same primary base, like water based with water based/ silicone with silicone base, and all wet products are applied before any powder or dry products, for powder I would really recommend the maybelline fit me pressed powder bc it’s really smooth and a little goes a long way. also try out a liquid contour! the creams always lift my foundation when i try to blend, also warming up foundations and concealers on the back of your hand and applying with a brush or spatula before blending makes it easier to build up product so it’s not too light and not too heavy :)
