The good thing about Grace is that when the nail grows out it isn't noticeable at all because the gel she uses is such high quality. Unlike acrylic nails that I've had done in the past it turns yellowish (not sure if anyone else had this problem?). But the
time frame for how long it lasts usually depends on your daily activities, if you're hard on your hands (sports, typing a lot etc..) and water exposure. For some, I would need to go back for a fill after 2.5 weeks and by then, one or two nails would have been slowly peeling off due to water. My hands are exposed to water everyday (besides showering, washing my face or just simply washing my hands) and then some, because I do the dishes a lot. I think the best part about it is that when the nails slowly come off due to wear and tear, it peels off nicely, doesn't damage your nail and doesn't hurt at all.
