This has definitely helped me

"This has definitely helped me not bite my nails! The taste is bitter and unpleasant, as it should. It doesn't transfer to e. g. , food if I'm cooking or eating. I also like that it has ingredients that help the nails grow stronger and healthier. Obvs doesn't fix the reasons I bite my nails (anxiety, stress), but reminds me to opt for better coping mechanisms!"

— Outi I. (5/5)

Amazing product through and through!

"Amazing product through and through! I'm all for natural nails but unfortunately my own nails are quite uneven, dull and thin. And this care polish checks all the boxes. It's staying power is no joke. I did my nails a week ago and went on an active holiday and it's still looking as good as new. No chipping or peeling. It gives my nails a very natural powdery satin look and actually fortifies them. Even one coat looks great and instantly improves an overall look of the nails."
