Opti-Nail® Fungal Nail Repair box


Opti-Nail® Fungal Nail Repair improves the appearance of nails damaged or discolored by fungus starting in just 2 days. The clinically proven, quick drying, triple action formula lightens, smooths, and moisturizes for clearer, healthier looking nails. No other product has the unique nail brightening formulation or no-mess pen applicator of Opti-Nail® Fungal Nail Repair.

No, the pen is not dried out. Opti-Nail® delivers a very thin layer of powerful solution that quickly absorbs into the nail surface. Your nail should have a visible shine which quickly fades as the solution dries. As long as you see some shine, you’ve applied enough. If you don’t see any shine, simply press down a bit harder with the applicator tip on your nail.

No other product has the unique nail brightening formulation or no-mess pen applicator of Opti-Nail® Fungal Nail Repair. Plus, Opti-Nail® is the only product clinically proven to start showing results in JUST 2 DAYS.

Opti-Nail® restores a healthier appearance to nails and begins to whiten and clarify with visible results starting in just 2 days. Even though you may see nail appearance start to improve in 2 days, for optimal results use Opti-Nail® twice daily for 4 weeks, then once daily after that to maintain healthy appearance of nails. It may take several weeks or months before you achieve your desired results.

Follow the directions on the product carton and insert. Remove the cap from the mess-free pen applicator and place tip of the pen on nail surface. Press down to dispense product. Apply a thin layer of product across the entire nail surface twice daily (morning and evening). The nail surface may appear wet. Avoid applying product to the skin around the nail. Allow nail to dry. Recap pen tightly after each use. After 4 weeks, apply once daily as needed to maintain look. Depending on the severity of the discoloration, longer application may be needed to achieve full effect.
Helpful Tips:

  • Remove nail polish before applying Opti-Nail®.
  • Use a cotton swab to remove excess solution from the cuticles and the skin of the toe or finger.
  • After application, allow the nail to dry for a few minutes before putting on socks or shoes.

Apply to the affected nail(s) twice daily for the first four weeks and once daily thereafter, until you have achieved the desired look.

Since Opti-Nail® works on the nail surface, nail polish will need to be removed in order for the product to improve nail appearance and achieve the desired results.

Opti-Nail® does not treat, cure or prevent fungal infections but can help improve the appearance of nails damaged by nail fungus starting in just 2 days.

Consult with your doctor prior to use if you’re pregnant or breastfeeding.

Apply Opti-Nail® only to the nail surface and avoid applying the product to skin around the nail. Irritation may occur if you apply Opti-Nail® to damaged skin. Also, avoid contact with eyes and mucus membranes.



Opti-Nail® 2-in-1 Fungal Nail Repair + Antifungal box

Opti-Nail®2-in1 contains two different formulas in one package – (1) a cosmetic to improve the appearance of fungal nails and (2) an antifungal drug product to treat fungus on the skin around the nails.

Untreated skin fungus on/between the toes can be a fungal reservoir for infecting healthy toenails, and fungal toenails can infect skin between/around the toes. For this reason, Opti-Nail®2-in-1 provides a dual solution (1) a cosmetic to improve the appearance of yellow, discolored fungal toenail and (2) an antifungal to treat fungus on the skin around the toenail and on/between the toes and to help prevent fungus from spreading to other skin areas and other toenails.

Clinical testing shows that the cosmetic improves the appearance of discolored toenails damaged by fungus starting after 2 days of twice daily use. The skin may take longer to show improvements. We recommend to use the entire product (step 1 and step 2) twice daily for at least 4 weeks. Results may vary depending on the severity of your condition.

Always apply step 1 before step 2. Avoid applying Step 1 cosmetic to your skin. If you get any product on your skin, use a cotton swab to wipe off the leftover liquid from the cuticles and the skin. Make sure to re-cap each product after use.

No, you have to remove nail polish before using the Opti-Nail®cosmetic Step 1 so that you can get the desired result.

Follow the label instructions and detailed directions on the package insert. First remove nail polish then clean your feet and toes. Step 1 – apply the cosmetic to your yellow, discolored fungus damaged toenails, then Step 2 – apply the antifungal to the skin around your toenails and between your toes. Both the cosmetic formula for the nails and antifungal for the skin are to be applied twice daily for 4 weeks for optimum results.

Yes. Because fungus can reside on your skin at a low level without symptoms, the antifungal in Opti-Nail®2-in-1 can control and prevent fungus from spreading and infecting your skin or other toenails. The Cosmetic part of the formula is intended to improve the appearance of yellow, discolored toenails damaged by fungus.
