La-Roche-Posay Color Correcting Pen is a liquid concealer in a small pencil like tube.  You twist the knob at the base of the tube and concealer comes out onto an applicator brush.

I used about 3 twist of product to correct imperfect colors on my face from age spots to redness.  I also applied this product under my eyes, as it is marketed to cover dark circles.  While I don't have a pronounced problem with under-eye dark circles, I do have imperfect skin from age (53).

The product came tightly wrapped in plastic, which was hard to remove.  I had to use scissors.  While it's good to have a seal on makeup products, this was a little overboard.  It took me several minutes to get a grip on the plastic and cut away the seal.

I have fair skin and would have chosen a lighter shade than the shade I received, but the dark beige actually did cover age spots and red areas on my face.  I applied the product with the applicator brush then blended it in with my fingertips.

The coverage capabilities with this product are good.  My face looks great after application and I haven't even applied foundation yet.

The concealer works great, but the tube is very small.  With the amount of product I used, I can't see this tube lasting more than a few weeks.  I prefer concealer to come in a creme form, preferably in a jar so I can monitor the amount and not run out. This applicator tube is solid white and you won't know you're out until you are out.  Therefore  I am not a fan of the delivery system.
