I bought this product for under-eye circles. I was immediately very impressed with how well the peach colour corrected. (All this time, I've been using a yellow colour corrector or a lighter skin tone). I was, however, completely thrown off by the "glow" of this product. My under eyes ended up looking strangely greasy while the rest of my face looked normal...
I use Sappho products on my skin. This might not be an issue if you used Fitglow because all of their products may leave the same glow. (I use the Lumi firm cream, and it certainly has a glow to it).
After some experiment, I realized that two to three light dusting of setting powder (with a minute between applications) combatted this issue. Now that I know this, I am impressed. The coverage looks very natural because it never gets dry, cakey or creases. It feels more like a moisturizing eye cream than makeup, but it still gives good coverage. The peach colour is a game-changer. It combats my purple under-eye circles but still blends well into my skin tone even if I only wear concealer and powder.
It is under-eye specific, so it's not very versatile. (Doesn't cover blemishes well but that's not what it's intended for).
It's pricey, but it only takes a few dabs per eye, so I hope this bottle will last a LONG time. If you have the money for it (and you need an under-eye corrector daily), I think it's worth the splurge.
