Twist and Cover Concealer

This product is weird, most of the time it comes out liquidy and doesn't cover absolutely anything (I have medium dark circles under my eyes) but a week ago I decided to give it one last try before...

<b>What is it?</b><br> Concealer with a similar idea to YSL Touch Eclat and others like it. Pen format with brush on top where the liquid concealer inside is pumped up with the push of a button....
