FungaBeam is a compact home device marketed to treat toenail fungus (onychomycosis) using light-based therapy. The makers position it as an at-home alternative to clinic lasers or long courses of oral antifungal meds. It’s designed to be easy to use: you aim the light at the affected nail(s) for short sessions over the course of weeks. Think of the device like a focused flashlight with a purpose. The company says the specific wavelength of light penetrates the nail and creates an environment that’s hostile to the fungal cells, helping reduce infection over time. It’s not an instant zap — the idea is repeated, consistent exposure weakens the fungus and allows healthier nail to slowly grow back. FungaBeam can reduce discoloration and thickness and may stop progression for some users. However, fungal infections live deep in the nail bed; a full, cosmetically perfect nail can take many months to grow back. Treating early-stage infections gives better odds than trying to reverse long-standing, severely damaged nails. Prices vary by retailer and promotions.
