i am currently on my 5th bottle of this stuff. i paint my nails on an almost daily basis, mind you.. and it is most often before bedtime. we ALL know about the dreaded 'sheet marks' that you get when going to bed after doing a fresh manicure. not a good look. this product will end your sheet mark woes. i don't use it every time i do a mani because i usually use Seche Vite as a top coat and that stuff dries hard as a rock in almost no time flat.. but if i'm ever in a major rush or if i'm stuck using a different top coat or a matte or textured polish that doesn't need a top coat, i ALWAYS finish with these Essie Quick-E drops and it does the trick. make sure you apply it after you think the polish is dry and let the product sit on the nails and soak in for a good 5 minutes. i have not had any problems with sheet marks since i started using this stuff over a year ago and i will continue to purchase it. keep in mind, this product will not do any good speeding up the dry time of regular coats of polish, it works best as a finishing product. you need to allow your polish enough time to dry before using this.
