Why is the air cushion effect like this

As a humble office worker who has been troubled by acne and oily skin for many years, I have had enough of fighting against makeup every morning! Either you can't cover up the red blood streaks on your acne scars, like a tabby cat, or your makeup is thick enough to look like a mask, and in the afternoon, you'll have mottled and new pimples coming out. It wasn't until I tried my best friend's Fancy Muse refined air cushion, which really could be the perfect base makeup for oily acne skin!
