Help! Makeup is separating

I used to wear foundation all the time and after years of struggling with it and dealing with acne I gave up. I find makeup extremely overwhelming, but yesterday I decided to try again. I went to Sephora and the saleswoman walked me through a very lightweight routine that she said was good for acne-prone skin. It's not even technically foundation, just tinted sunscreen, so I hoped there wouldn't be an issue. I talked through every step with her and followed her instructions exactly.

I had such high hopes and was devestated today to realize how cakey it looked after four hours of wearing it. The routine is as follows:

-First wash my face and moisterize with Cerave night cream

-Ciele SPF 50 tint and protect tinted sunscreen (the lady said I didn't need primer with this routine)

-Tower 28 concealer on undereyes (this is the only thing I picked myself)

-Makeup by Mario bronzer

-Saie slip tint setting powder

In the evening I use differen for my acne and cerave night cream again.

Does anyone have advice for me? The lady at Sephora also suggested setting spray but I am worried that the more products I put on the worse it will get. I also have naturally big pores and everything settles in them.
