This is almost the most perfect cosmetic item I've ever purchased. It's really 98-99% of the way there. It goes on smoothly and evenly and if you let it rest you can see a real, significant difference - it's pretty amazing. Immediate satisfaction! It seriously decreases any bags under your eyes, and even better, evens out the color of your skin: no more darker, or deeper, or more pink color below your eyes - it's amazing - it takes 5 years off, or a hard night partying. The reason it's not 5 stars, not 100%, is that it's a little too thick. If you aren't careful in applying evenly or use too much, it can crease. You know how you can get an eyeshadow/eyeliner crease on your upper lid? You DON'T want a crease, or a dried extra product spot, under your eyes or on the sides of them. But you can use an undereye cream or gel first and then apply this, which will thin it out just enough and make sure it's all good.
