Beukow Nail Fungus Treatment Pen, Extra-Strength 4-Pack — 25% Undecenoic Acid & Tea Tree Oil, Precision Tip

Beukow Nail Fungus Treatment Pen is a precision applicator formula with 25% undecenoic acid plus botanical oils designed to help improve the appearance of damaged, thickened, or discolored nails.

This compact 4-pack of Beukow pens combines an extra-strength active ingredient with supportive natural oils to address the visible signs of nail distress. The formula is presented in a twist-to-dispense pen with a fine tip for targeted, low-mess application. Intended for regular topical use on fingernails and toenails, the pens are formulated for non-irritating daily care while fitting easily into a bathroom kit or travel bag.

How does the Beukow pen address thick or discolored nails?

The treatment delivers a concentrated 25% undecenoic acid active to the nail surface, paired with emollient oils that help soften and smooth roughened nails. Consistent twice-daily application helps the product reach and coat affected nail areas while supportive ingredients help improve surface texture.

• 25% undecenoic acid for concentrated topical support
• Tea tree and almond oils to hydrate and reduce flakiness
• Vitamin E to help condition the nail plate
• Use twice daily for 15–30 days depending on nail thickness

How do I use the pen for the best results?

Begin by gently filing the nail to reduce thickness and create a smooth surface. Remove the cap, twist the pen base to dispense, and apply the product directly to the affected nail and edges; this precision tip minimizes waste and keeps application tidy.

• File nail until thinner and smoother before application
• Twist base to prime product, then apply with the pen tip
• Apply twice daily and continue use for 15–30 days
• Maintain hygiene—clean, dry nails and change socks/shoes regularly

Is this formula gentle enough for regular use?

Yes — the Beukow formula balances a potent active with gentle botanical oils to reduce irritation risk. The product is designed for topical use on nails and surrounding skin and aims to moisturize while delivering its active ingredient.

• Non-irritating base with skin-conditioning almond oil
• Tea tree oil included for its naturally derived properties
• Vitamin E provides additional moisturizing support
• Suitable for daily use when applied as directed
