I've settled on a cushion I bought with my own money.

It's Espoir Pro Tailor Be Velvet Cover Cushion shade 20!

I actually thought it was a bit lighter than my skin tone, but it turned out to be a perfect match! However, I think you need to apply a base layer of skincare beforehand to prevent it from caking. I bought two more refills haha. I used to use a Clio cushion, but theirs didn't suit me at all. It broke down so unevenly, but this one seems to wear off nicely even after time passes, so I use it well even when wearing a mask!
