While shopping at Sephora this weekend, I picked up Benefit's new eye primer - Stay Don't Stray. I've used this for three days, and I must say, I absolutely love it. I do need to tell you though, I'm not sure this product will work for all skin tones. It's a very light nude shade that I'm not sure would work for olive or dark skin tones. On me it works fabulous, but I am very pale. I usually always put concealer and then my MAC MSF under my eyes, so this helps that stay there all day. I have noticed a dramatic difference in the staying power of my concealer under my eye area which is the place I need it the most. Using this as a concealer primer is quite tricky though. You need to make sure it is completely blended and that you use a concealer that is quite thin...I use the MAC Select Moisture Coverage Concealer under my eye area so it works out great with that. It also works similar to Powderflage, brightening the eye area to minimize the appearance of fine lines and wrinkles.
As a primer for your eyeshadows, it works quite well. My eyeshadows have been staying on all day, but I much prefer their discontinued F Y Eye as a shadow primer. Shadows don't blend the same on top of the new primer, but they do stay all day. All in all, I think this is a great product. Your eyeshadows stay vibrant and true to color all day. It also hydrates the eye area to lock in moisture, and fights signs of aging with Vitamins C & E. It's also free of parabens, which we all try to stay away from. It really goes on smooth and covers darkness and redness really well.
Just a note about application. This product comes in a cylinder with a pump dispenser. Be careful when pumping out your product. About half a pump is all you need for both eyes. If you have any remaining, you can use it on areas that you will be applying concealer to keep your concealer on all day.
