As someone with majorly dark under eye circles, this product seriously surprised me. I previously relied upon Vichy Dermablend concealer to cover up my dark circles, but it was discontinued years ago and the stash I've hoarded of that product is getting quite low. I did not expect Touche Magique to work, but based on the reviews and price (about $13 at the drug store), I picked it up. When I saw how thin it was in consistency, I was even more skeptical. But it works. It doesn't completely obliterate under eye circles, but neither did the Dermablend. It does a good job of covering them up and making them appear brighter. The staying power has also been surprisingly good. As has been said by previous reviewers, this probably won't cover up blemishes, but I did dab it on the pinkish folds of my nose and it worked well to conceal and brighten there, too.
The packaging: I was annoyed at how many times I had to twist the end to get the product out the first time I used it, but since then I've only had to click a couple times to dispense it. Aside from that minor annoyance, I honestly kind of like the thin tube and its built-in brush.
