Dangerous.
This didn’t work and it literally made my natural nails curl inward and pinch my finger. This product was dangerous. I used it as directed although it comes with no instructions. Within 2 min I felt an odd pressure sensation on my nails and by the third minute wiped it off. It took about an hour for my nail to return to normal. I will never ever use this again. Beware!
