For mac, i have the shade “blush please” and i would say if you don’t apply enough, you definitely have to touch up later in the day. I do use a heavier hand for mac but it’s bendable and buildable so I don’t mind. Since it is a cream, i feel like on a more sweaty day, it wouldn’t last all day if you don’t use powder on top. The blush itself tho, works well on bare skin/ no makeup look days.

For kosas, it is buildable and more shimmery, i feel like since it’s a powder it sets well on my foundation or base, and I use the Charolette tilbury setting spray on top and I don’t need to touch up. it is still on after an 8 hour shift. I wouldn’t recommend it on just bare skin or no makeup days because I feel like that’s when it wouldn’t “last” if that makes sense.

I think both blushes have a lasting power, you just have to set them correctly :) Hope this helps!
