When will I see results?

Depending on the severity of your fungus, you may begin to see results within four weeks. As the weeks and months go on, new healthy skin will begin to appear. It’s important to keep applying the solution on the affected area around the cuticle and under the tip of your nail to keep the area clear and stop the infection from spreading.

How do I use Fungi-Nail® Toe & Foot® Pen Brush Applicator?


Clean the affected area with soap and water and dry well.


Cut nails straight across and then file so they are slightly round at the tips.


Remove the cap of the pen. Point the brush downward and then twist the base to saturate brush. If you do not hear a click, turn the base the other way. Do not over-twist.

Apply brush to skin to make sure solution comes out (please note the solution is clear). Apply Fungi-Nail around the cuticle and underneath the edge of the nail twice a day.

After 2 months using this product, my finger is perfect again. Thank you so much.


Hi, I just wanted to drop you guys a quick thank you. Your product is the first to actually work on the fungus I HAD. It’s HUGE to lose that self-consciousness. So many other products have been worthless and I had almost lost hope on ever being done with the ordeal. THANK YOU!!!


Just a short note, telling you how impressed I was with your ‘Fungi-Nail’ product, it cleared up my problem in about 5 weeks. Thanks!
