Nail Fungus Treatment in Seoul: Testing, Antifungals and Laser for Clearer Nails
Nail fungus (onychomycosis) makes nails thick, discoloured and brittle. A dermatologist confirms the infection with testing, then uses antifungal medication and laser to help a healthy nail grow back.

How is nail fungus treated?
Nail fungus is treated with oral antifungals such as terbinafine for moderate to severe cases, topical antifungal lacquers for mild cases, and Nd:YAG laser as a supportive or alternative option. Fingernails take about 6 months and toenails 9–12 months to grow out clear.
Signs
Is it nail fungus?
About half of abnormal nails are not fungal, so testing matters.
Discolouration
Yellow, white or brown patches.
Thickening
Nails become hard to trim.
Brittleness
Crumbling or ragged edges.
Lifting
Nail separates from its bed.
Toenails
Most common site; see toe fungus.
Look‑alikes
Psoriasis, injury or a dark streak; see melanoma.
How it works
Clear the infection, grow a new nail
Antifungals stop the fungus in the nail bed; laser heat damages fungal cells. The damaged nail does not recover, but a healthy nail gradually replaces it from the base.
