Frequently Asked Questions
Why is toenail fungus so hard to treat?
The fungus lives under the nail plate, where topical treatments struggle to penetrate. The nail grows slowly (12–18 months for a full cycle), so treatment requires patience. Our CO2 laser can reach the fungus directly through the nail plate.
Should I take oral antifungal medication?
Oral antifungals are effective but require liver function monitoring and may interact with other medications. Dr. Quach will discuss all options and help you choose the safest, most effective approach for your health profile.
