I've been going on and on about the terrible shape my nails are in this past year, I know. I've tried all kind of nail-polishes that claims to strengthen the nails, but they don't help. I've painted my nails a lot during this time, but the polishes always peel, and then I start to peel my nails too. This polish from essie, is the first one I've tried in a looong while that didn't peel for at least four days, and continues looking good. It's called "fill the gap" and is an anti-age treatment... it is also supposed to even out damages to the nails. And it might, I don't know. I just know it looks fine after several days, the color is bland but nice and well, I will continue to use it.
