Let me introduce a cushion I recommend for summer hehe.

My makeup breaks down quickly in the summer due to sweat and oil.

Since I started using the Leaders Glamour Cushion, that has definitely decreased, so it is a cushion I make sure to use every summer. The SPF is also high, so I don't even need to use a separate sunscreen haha. The price isn't too burdensome either, so it is a real gem that I use often. You should give it a try too; I highly recommend it.
