Lyssera Toenail Fungus Treatment Pen — 4-Pack, 25% Undecylenic Acid & Tea Tree Oil, Brush-tip Precision

Lyssera Toenail Fungus Treatment Pen is a precision brush-tip topical solution with 25% undecylenic acid and tea tree oil designed to support visible improvement of thick, yellow, and brittle nails.

If you’re managing discolored, rough, or brittle toenails and fingernails and want a targeted daily option, this four‑pack of easy-to-use pens gives concentrated care in a fast-drying, non-greasy formula. The pens deliver a liquid treatment directly to the nail surface and surrounding edges so you can maintain a consistent routine at home, on the go, or keep separate pens for multiple nails.

How does this pen apply treatment to hard-to-reach nail areas?

The Lyssera pen features a fine brush tip that deposits liquid precisely where the nail needs it, including under nail edges and along sidewalls. That focused application reduces waste and helps the active ingredients contact the nail surface evenly.

• Brush-tip applicator for direct placement on nail plates and edges
• Thin liquid formula spreads evenly across ridges and under tips
• Fast-drying, non-sticky finish so you can resume activities quickly

What active ingredients are in the formula and what do they do?

This treatment combines 25% undecylenic acid with tea tree oil in a lightweight vehicle. Undecylenic acid is the primary active agent used in many topical fungal care products, while tea tree oil is included for its traditional topical use and its fresh scent.

• 25% undecylenic acid concentration for concentrated topical coverage
• Tea tree oil added for complementary topical support and scent
• Non-greasy base that dries quickly for daily application

How should I use these pens for best results?

For a simple at-home routine, clean and file the nail surface, then apply the treatment two to three times daily. Consistent, repeated application is recommended to help improve the nail’s appearance over time; allow each application to dry fully before covering with socks or shoes.

• Step 1: Clean and dry nails; remove debris and loose lacquer
• Step 2: File thickened or uneven areas to allow better product penetration
• Step 3: Apply with brush 2–3 times daily and let dry completely

Why buy the 4‑pack and how can it fit into my routine?

The four-pen set gives flexibility and value: keep one at home, one in a travel bag, one in a gym kit, and a spare for quick replacement. Multiple pens also help maintain hygiene by reducing cross-contamination between different hands or feet.

• Four individual pens extend total treatment time without reordering
• Convenient for travel, work, or separate-use preferences
• Compact pens fit easily into toiletries or first-aid kits

Who is this for: The Lyssera Toenail Fungus Treatment Pen set is intended for adults seeking a topical, daily-use option to address visible nail concerns such as yellowing, thickening, brittleness, and surface roughness. It’s suited to people who prefer a targeted brush applicator and a fast-drying, non-greasy product that can be used consistently at home, while traveling, or stored in multiple locations for convenient access.
