DeepClear Nail Treatment Pen is a topical anti-fungal nail treatment applied with a twist pen, designed to tackle fungal nail infections at the root. Unlike creams, oils, and paints that only sit on the nail surface, its two-stage approach is built to open the hard nail so proven active ingredients can finally reach the fungus beneath. Applied directly to the affected nail twice a day, it is a tablet-free option marketed as safe alongside existing medications, with the maker claiming healthy new nail growth within 14 days.

The formula works in two stages. First, urea softens the hard keratin of the nail and creates microscopic channels through it. Then undecylenic acid (25%) travels through those channels to stop the fungal roots from replicating. The maker describes undecylenic acid as an MHRA- and FDA-approved anti-fungal agent originally studied in WWII military research, and notes the treatment stays entirely topical so nothing passes through the liver. These are the brand’s claims rather than independent medical advice.

• Backed by a 60-day money-back guarantee

How It Works

DeepClear is built around the idea that other treatments fail because they can’t get through the nail’s hard keratin. In stage one, urea softens the nail and opens microscopic channels through it — an approach the maker notes dermatologists have used for decades. In stage two, undecylenic acid passes through those channels to stop the fungal roots from replicating, described as cutting off the fire’s oxygen so it’s starved, weakened, and dies off. Everything is designed to stay on the nail, with nothing entering the bloodstream. These descriptions are marketing claims, not a substitute for professional medical care.

Key Ingredients

• Urea: softens the hard nail structure and opens channels so active ingredients can pass through to the infection beneath
• Undecylenic Acid (25%): stops fungal roots from replicating; the MHRA- and FDA-approved active ingredient at the core of the formula
• Oregano Oil (Carvacrol + Thymol): described as helping break down existing fungal cells
• Tea Tree Oil: a proven anti-fungal agent that, with urea opening the pathway, can finally reach its target

How to Use

Using DeepClear takes about 30 seconds, twice daily, in three steps. First, twist the pen and apply the treatment directly to the affected nail, morning and evening. Second, let it work — urea softens the nail while the anti-fungal agent passes through, with nothing to feel as you carry on with your day. Third, watch it grow out: fresh, healthy nail appears from the base while the old yellowed section grows out to be clipped away, a little more clear nail showing each week.

What to Expect

Results build gradually. According to the maker, the fungus stops spreading within the first week once the active ingredient reaches the roots, and most people notice clear new nail growth at the base within 14 days. The old yellowed section then grows out over the following weeks, with longer-standing infections taking longer to grow out completely.

FAQ

How is this different from everything else I’ve tried?

Other creams, oils, and paints sit on the nail’s surface and can’t easily get through the keratin. DeepClear uses urea to soften the nail first and open microscopic channels, so undecylenic acid can travel through to target the fungal roots beneath — the step the maker says other products leave out.

I take statins and blood pressure tablets. Is it safe to use?

The maker states DeepClear is 100% topical, applied directly to the nail, with nothing entering the bloodstream or passing through the liver, and describes it as formulated for people advised that oral options like terbinafine carried too much risk. As always, check with your own doctor about your specific medications.

I’ve had fungal nail for over ten years. Is it too late?

The maker says no — it cites clinical trial figures for undecylenic acid in severe, long-standing infections and notes that longer-standing cases simply take longer to grow out completely.

How quickly will I see results?

The maker says the fungus stops spreading within the first week, with most people noticing clear new nail growth at the base within 14 days and the yellowed section growing out over the following weeks.
