According to Benefit's webpage:
This dual-action power primer works 360° around the eyes to make concealers and eyeshadows stay put. Concealers don't crease, eyeshadows stay vibrant and true, you'll wonder how you ever lived without it!
Gently pump a small amount onto the back of your hand. Apply 3 tiny dots under your eyes with fingertips and blend. Let set, then apply concealers & eyeshadows as usual.
