I'm such a Seche Vita addict
Nothing else keeps my manicure chip free for up to two weeks - not to mention the shine it gives! People have often mistaken it for shellac.
lol An alternative to Seche is Essie's Good To Go. I think it last just as long, but it doesn't have the same amount of shine though.
I recently discovered Zoya (I am a DEVOTED China Glaze girl) and I'm really loving the bottles I've purchased so far!
