Nail Fungus

Onychomycosis is a fungal infection affecting the nails, commonly causing thickening, discoloration and brittleness. City Clinic’s laser treatment for nail fungus offers a safe, non-invasive and effective solution, destroying the fungus at its root without damaging the surrounding tissue.

At City Clinic Marbella, we use advanced Q-Switched nanosecond laser technology to treat nail fungus. The laser energy penetrates the nail plate, generating heat that eradicates fungal colonies beneath the nail surface. The treatment is completely safe, painless and compatible with all skin types, helping restore the nail’s natural appearance and preventing recurrence when combined with proper hygiene and maintenance.
