Toe Fungus Treatment in Seoul: Clear Thick, Yellow Toenails with Medication and Laser
Toenail fungus (onychomycosis) makes nails yellow, thick and crumbly, and rarely clears on its own. A dermatologist confirms the diagnosis, then combines antifungal medication with laser for a clearer new nail.

What is the best treatment for toenail fungus?
The most effective treatment for toenail fungus is oral antifungal medication such as terbinafine, often combined with topical antifungals and Nd:YAG laser for patients who want to avoid or support tablets. Because toenails grow slowly, a clear nail takes 9–12 months to grow out fully.
Symptoms and causes
Signs of toenail fungus
Other conditions can look similar, so testing comes first.
Yellow or brown nails
Discolouration starting at the tip or sides.
Thickened nails
Hard to cut and may press in shoes.
Crumbling edges
Brittle, ragged nail ends.
Lifting nail
Separation from the nail bed.
Athlete’s foot
Skin fungus between toes often spreads to nails.
Look‑alikes
Psoriasis, trauma or a dark streak need a different plan; see melanoma.
How it works
Treat the fungus, then grow a healthy nail
Antifungal medicine kills the fungus within the nail bed. Laser heats the nail to damage fungal cells and can support medication. The infected nail then grows out and is replaced by a clear nail.
