Frequently Asked Questions
How does this antifungal pen work?
How does this antifungal pen work?
The Stycove Antifungal Pen features a maximum-strength 25% Undecylenic Acid formula. Paired with our deep penetration technology, the liquid penetrates through the nail to reach the nail bed, effectively stopping fungus at the source while restoring the natural, healthy appearance of your nail.
How long will it take to see visible results?
How long will it take to see visible results?
While individual results vary based on nail growth speed and the severity of the infection, most customers notice visible improvements in nail clarity and texture within 2 to 4 weeks. Because eliminating fungus is a gradual process, we highly recommend consistent daily use until a healthy new nail fully grows out.
Is the application messy or complicated?
Is the application messy or complicated?
Not at all! Our innovative brush-tip pen design makes application a breeze. Simply twist the base to dispense the clear liquid onto the soft brush, and paint it directly onto the affected nail and cuticle. It's precise, 100% mess-free, and takes just seconds a day.
How long does one 3ml pen last?
How long does one 3ml pen last?
One 3ml (0.1 fl. oz) pen typically lasts about 3 to 4 weeks if applied twice daily to 1-2 nails. For a complete and uninterrupted treatment cycle, we highly recommend grabbing a multi-pen bundle so you don't run out before the new nail fully restores.
Can I wear nail polish while using this treatment?
Can I wear nail polish while using this treatment?
For maximum absorption and the fastest results, we strongly recommend applying the solution to bare nails. Nail polish or acrylics will block the active ingredients from penetrating the nail bed. It's best to give your nails a breather so they can heal properly!
Do I need to file or trim my nails before applying?
Do I need to file or trim my nails before applying?
Yes, prep makes a big difference! Wash and thoroughly dry the affected area first. If your fungal nail has become thickened, gently filing the surface once a week will help the 25% Undecylenic Acid penetrate much deeper and work faster.
Does it work on both toenails and fingernails?
Does it work on both toenails and fingernails?
Absolutely. The Stycove Antifungal Pen is formulated for safe, powerful fungal inhibition and complete nail restoration on both fingers and toes.
Is it safe to use? Will it sting or burn?
Is it safe to use? Will it sting or burn?
Yes, our formula is extremely safe for daily topical use. Most users experience zero discomfort. Because of its deep penetrating power, you might feel a very slight, temporary tingling sensation if your nail bed is severely damaged—this simply means the active ingredients are getting to work!
