I initially hated this and couldn't believe that Maybelline would put out such an awful product. My go-to concealer is the Nars creamy, but I forgot to pack it on a vacation and decided to head to the nearest supermarket near my hotel to get a substitute. It was the summer holidays so I thought the Superstay was the most appropriate as I was going to be outdoors and sweating quite a bit. First day I tried it on my undereye circles and some redness near my mouth and it was a disaster! I had to wash it all off and re-do my entire face and skip concealer because of how badly it creased and caked. I thought it was the most ridiculous product ever and was determined to throw it in the bin. However, I decided to give it another chance a few days after as I was invited to a party and I really wanted to do a flawless-face makeup look. I used a wet sponge this time and started blending immediately after the product hit my skin (you need to be really fast!). Surprisingly, it worked perfectly. My undereye area looked really bright and porcelain-smooth and I was surprised by how good the finish was when blended quickly with a wet tool. Even more, I was surprised at how well it held up after a very very long, humid night at an outdoor party. I'm convinced I could wear this through a session at the gym. I'm not overly-thrilled by the shade selection and I think the shades all lean overly towards the pinkish. I use a yellow-based setting powder over this though, so this wasn't too much of an issue. However, I will probably only use this exclusively as an undereye concealer and not as a spot-corrector, as the undertone just seems too off. Overall, this won't replace my Nars, but it is a great product to have as back-up. You need to work at your application technique, but given how inexpensive it is, and how great the pay-off was, I felt it was worth the learning curve. Just remember to blend it in as soon as it hits your face. Work on one section at a time, and NEVER EVER let it sit on your skin for more than a few seconds. Once it dries up, it is impossible to work with and you'll probably have to use make-up remover to get rid of it and start over. Dryer skins probably should stay away completely though. And I probably will not use this in colder, dryer weather either. But if you have greasy skin like me and need an inexpensive concealer for the summer or hot, humid weather, then you might want to try this.
