Frequently Asked Questions

How do I use it? +

Twist the pen to release the formula, then paint directly onto the affected nail and surrounding skin. Allow to dry fully before putting on socks or shoes.

How often should I use it? +

Apply twice daily — once in the morning and once at night — for best results. Consistent use is key to seeing visible improvement.

Is it safe for sensitive skin? +

Yes. The formula is designed for use on nails and the surrounding skin. If you experience any irritation, discontinue use and consult a healthcare professional.

When will I see results? +

Most customers notice visible changes in nail appearance within 3–6 weeks of consistent twice-daily use. Nails grow slowly, so continued use over 8–12 weeks delivers the most noticeable improvement.
