L'Oreal already got my money on this twice, since I bought two shades, maybe a year ago, thinking I'd like the miracle blur and all. In the last year, though, it's been mostly neglected.
I bought the Light shade first (the middle shade), and since I'd bought it in winter I found it was too dark for me, and then picked up the Fair, thinking it'd be a better match. It was, sort of. I'm kind of a light neutral skin tone, where in the world of foundations, usually the second or third option (going light to dark) works well for me. So blending the two shades gets a decent match for me, but it still doesn't work.
I've tried a number of ways to work with this concealer, and I haven't really struck gold.
As a concealer it does cover some darker spots, but if I have some unevenness in texture, especially if my skin is on the dry side, it just accentuates the trouble spot and does nothing to conceal.
Under my eyes, I had hopes for the darker shade, and it was a good match for undereye circles, blending and blurring a bit and blocking out some dark circle. I thought, yes, this is working, my undereye circles are diminished -- and 15 minutes later, it looked patchy and my undereye lines were amplified.
The best use I've found, personally, is to mix it with moisturizer and make a tinted moisturizer out of it. It gets the most natural look there, and I think with this formula I need added moisturizer to make it work. But that said, I have other, cheaper, and better-matching tinted moisturizers and BB creams that perform better for me. Though when mixed with a moisturizer and applied to my face, it does make the clear, line-free areas of my face look better. But that's not what I wanted it for, since the formula (being concealer) is heavier, and I don't want that on my cheeks and forehead.
One last thing I don't care for is the tube. I wish it had a narrower opening because I've found it quite easy to squirt out too much of this product.
A shame. I wanted to really like this and enjoy a bit of airbrushing magic, but it just didn't work for me.
