Frequently Asked Questions

Q: How does the anti-nail biting pen work to stop nail biting?

A: The pen uses Denatonium Benzoate, one of the most intensely bitter compounds known, to coat your nails with an unpleasant taste. Any time you unconsciously bring your fingers to your mouth, the extreme bitterness acts as an immediate sensory deterrent, helping your brain gradually unlearn the nail-biting habit over time.

Q: Is the anti-nail biting formula safe for children?

A: Yes! The formula is designed to be gentle and safe for both adults and children. The key active ingredient, Denatonium Benzoate, is widely used as a bittering agent in household products and is considered safe at cosmetic concentrations. Always keep the pen out of reach of very young children when not in use.

Q: How often should I apply the anti-nail biting pen?

A: For best results, apply the pen twice a day — once in the morning and once in the evening. Be sure to reapply after washing your hands, as water can wash away the coating. Consistent use over several weeks is recommended to help break the habit effectively.

Q: Will the formula leave a visible residue on my nails?

A: No. The formula dries clear and transparent in approximately 30 seconds, so it is virtually invisible on your nails. It won't interfere with nail polish or affect the appearance of your nails in any way.
