The Acetocaustin® Nail Biting Pen offers an effective way to stop nail biting, enriched with Bitrex, the world's most bitter substance to deter biting. With just one application per day, the pen helps stop the habit. The Acetocaustin® Nail Biting Pen is applied to the nail using the easy-to-use brush applicator. The applied liquid is invisible and non-shiny. The Acetocaustin® Nail Biting Pen provides targeted application, applying only to the nail edge, side of the nail, or cuticle. Thanks to Bitrex, full-surface application to the nail is not necessary. For optimal results, use of the pen for at least 21 days is recommended, based on scientific findings that this is the average time it takes to change habits. The pen dries quickly, and the intense bitter taste gradually dissipates within a day. If needed, the solution can be easily washed off with regular hand soap.

The Acetocaustin® pen for nail biting is also excellent for breaking the thumb-sucking habit. Simply apply a small amount of the liquid to the tip of the thumbnail. Use in children aged three and older is possible under supervision.

What is nail biting?

Nail biting, or onychophagia (from the Greek word meaning "nail eater"), is a relatively common habit affecting people of all ages. It is considered a chronic or compulsive habit that can be triggered by anxiety, stress, insecurity, and other factors.
