My makeup is breaking down too much. What is the cause?

Maybe it's because the weather is getting hotter, but my makeup is wearing off so fast.

Even if I put a lot of effort into getting ready in the morning, by lunchtime my nose and forehead are shiny,
The foundation is clumping around my nasolabial folds and the sides of my nose, so it looks really messy !!!

I'm so, so stressed out these days...

I'm not sure if it's because I applied too much base makeup, or if it's actually due to a lack of moisture.

I've tried changing the cushion and using a setting spray, but I don't think there is as much of a difference as I expected.

The photo below shows my skin condition right after applying makeup, and

This photo was taken a little while after I went out 😂

For those of you who experienced severe makeup breakdown, have you found the cause?

Please let me know if you know of any methods that have worked for you, or if I should reduce my base makeup or use powder!
