Spec sheet

A 25% undecylenic acid formula paired with tea tree oil gives this nail treatment a clearly defined active blend. The pen format is designed for targeted application, while the included files make it a practical set to keep with your nail-care supplies.

• Name: Toenail fungus treatment
• Active ingredient: 25% undecylenic acid
• Also contains: Tea tree oil
• What’s included: 3 pens and 5 nail files

The formula is intended to help reduce discoloration and improve the appearance of thick, brittle nails. It is made for concerns affecting both toe and fingernails, so the same set can be used as part of a nail-care routine for either.

Best use cases

This set is intended for people addressing yellow-looking, thick, or brittle toenails or fingernails. Its pen format offers a focused alternative to treatment packaging that relies on a bottle-style applicator: the treatment is housed in a pen, making it convenient to keep alongside everyday nail-care items. The five files are included in the set for nail-care use, without needing to source them separately.

For a practical routine, keep the pens and files together and follow the product’s package directions for application. The active blend is the key differentiator for shoppers comparing nail treatments by ingredient, while the three-pen format provides multiple applicators in one set. It suits you if you want a targeted treatment format for the look of discolored or brittle nails, rather than a general-purpose nail-care product.

Purchasers have described the pen applicator as easy to use and have shared positive impressions of how their nails look with use. Feedback on drying time and skin irritation varies, so follow the package directions and pay attention to how your skin responds during use.

Practical tips

Keep the treatment near the rest of your nail-care supplies so it is easy to reach when you follow the product directions. Use the included files as part of your nail-care setup, and refer to the packaging for the recommended application method and frequency. The product is intended for nail concerns, including discoloration and a thick or brittle appearance, using it according to its directions keeps the routine focused on that purpose.

The three pens and five files also make the contents easy to identify before setting up your routine. If you are choosing between products, compare the active ingredient and applicator style: this set combines 25% undecylenic acid with tea tree oil and uses a pen format for application.
