LORAC Double Feature ($24) is a multi-tasking complexion perfector with an interesting design. The product comes in two parts; the swivel-up concealer stick and the doe-foot wand style vial of highlighter.
The twist-up stick is a creamy and pigmented consistency and it covers well with minimal creasing as the day goes on. It sets well with powder and is easily blended out with a finger or sponge. Included in the packaging is a "blender ball," which is a roller-ball such as you might see on some lip glosses or eye shadows, but it is clean and is meant to be used to smooth the concealer out and blend the harsh lines. The ball is somewhat effective, but I found better results using both my fingers and a wedge sponge. The inherent flaw in the blender ball, in my opinion, is that I don't find it to be very sanitary. You can wipe the ball off with a disinfectant wipe which might degrade the ball in time, or use a wet cloth, but then the moisture will get in below the ball and that might cause blending problems with it later. I think that while the blender ball is fairly superfluous, the concealer is pretty light in feel with heavy-duty results.
