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.

Test Microscopy / culture
Fingernails About 6 months
Toenails 9–12 months
Laser sessions 4–8

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.
