I recommend the Hera Black Cushion.

Although it is already a very famous product, I highly recommend the Hera Black Cushion Foundation, which I use frequently myself! First of all, the staying power and coverage are both excellent, and since it doesn't wear off easily, you can achieve a flawless complexion using just this cushion foundation alone. Haha. Including the refills, I have lost count of how many tubes I have gone through; it is a product I truly love.
