Lyssera Toenail Fungus Treatment Pen 4-Pack — 25% Undecylenic Acid & Tea Tree Oil, Fast-Drying Brush Tip

Lyssera Toenail Fungus Treatment Pen is a precision brush-tip topical formula containing 25% undecylenic acid and tea tree oil to support daily care for thick, discolored, or brittle toenails and fingernails.

This four-piece set is designed to fit into a simple at-home routine that targets visible nail concerns such as yellowing, rough texture, and splitting. The pens deliver a concentrated, fast-drying liquid directly to the nail surface and edges for consistent application. With a non-greasy formula and a compact brush tip, the treatment aims to make daily nail care easier to apply, maintain, and carry on the go.

How does the Lyssera pen work in a daily nail-care routine?

The pen is intended for repeated topical use: clean the nail, gently file the surface, then brush the treatment over the entire nail and surrounding edges. The brush-tip helps reach tight spaces and apply a thin, even layer that dries quickly without residue.

• Use 2–3 times daily for consistent coverage.
• Brush tip applies liquid to nail surface, edges, and undersides where accessible.
• Fast-drying, non-greasy consistency for easy daily wear.
• Compact pen fits into travel kits and gym bags for routine use.

What ingredients are included, and why are they used?

The primary active is undecylenic acid at a 25% concentration, a commonly chosen topical antifungal agent for nail care products. The formula also features tea tree oil and other supportive ingredients that help with application and scent. Ingredients are combined to create a spreadable, quick-drying topical solution suitable for nails.

• 25% undecylenic acid as the main topical active.
• Tea tree oil included for its traditional topical use and aroma.
• Lightweight carriers to help spread and dry without stickiness.
• Formulated for both toenails and fingernails with visible concerns.

How should I apply the treatment for best results?

For best consistency, follow a short three-step approach: clean, file, and apply. Make sure nails are dry before applying; brush the liquid across the nail and along the free edge. Repeat as directed for ongoing maintenance and replace pens in the set as needed to maintain a daily regimen.

• Step 1: Wash and fully dry the nails before application.
• Step 2: Gently file any thickened areas to improve surface contact.
• Step 3: Apply with the brush tip 2–3 times daily; allow to dry.
• Store pens upright in a cool, dry place when not in use.

Who is this for? This Lyssera 4-pack is for adults seeking a convenient, over-the-counter topical option to include in daily nail care. It suits people who prefer a brush-pen applicator for accuracy, those who travel frequently and need portable treatments, and anyone looking to address visible nail issues like yellowing, roughness, or brittleness as part of a regular grooming routine. Avoid use if you have known sensitivity to any ingredients; consult a healthcare professional with questions about interactions or persistent nail conditions.
