This double shot of makeup and anti-aging is a winner.  Aside from the fact the swirl of the two products looks really cool in the container, the concealer works very well under the eye.  While it does contain Olay Regenerist Serum, the pigment is just strong enough to cover up dark circles while still appearing luminous.  It is easy to apply because the consistency changes as you apply it to the skin.  While it looks cakey in the container, it turns to a smooth liquid on your skin.  Because of this, I recommend using your finger.  I try to use the ring finger because it offers the least pressure on the delicate eye area.  While you can’t really use this for blemishes because it is really creamy, I did use a little on my chin and nose instead of foundation and it works great!
