Firstly, there are no instructions printed anywhere on the bottle, so I just kind of had to figure out how long to leave it on by myself (thus, if I did it wrong, that's my own fault and you don't have to pay attention to this review). I brushed it over my cuticles, left it on for about 10-15 minutes, and then dabbed it off with a tissue. The results were immediate--right away, my cuticles looked amazing, even like I had just had a manicure. However, this only lasted for about and hour or two, and they went right back to being as dry as they'd been before. There wasn't much of a long term improvement benefit to using this product, and I don't want to keep reapplying it every hour.
