We'll suggest a care routine that's just right for you!
Can I use this routine if I'm already wearing gel polish or gels?
This routine is designed to be used on bare nails. If you have products on your nails, we recommend removing them before applying the routine.
Why use the S.O.S. Base every two days?
The S.O.S. Base works like a treatment polish. By renewing the application every two days without removing the previous layers, the active ingredients stay in contact with the nail to optimise their effectiveness throughout the treatment.
Can I use this routine continuously after 2 weeks?
It is recommended to take a break after 2 weeks to preserve the natural balance of your nails. To maintain the benefits, you can repeat the routine monthly.
