What is the best treatment for athlete's foot?

Since my mid-20s, I've been dealing with athlete's foot that suddenly appeared, and for over ten years now, my toes have been itchy several times a year, sometimes developing blister-like sores.

I have tried treatment with ointments and oral medication at the dermatology clinic, and I also used a few antifungal creams for athlete's foot, but at the time, the itching subsided a bit and seemed okay, but now it's back to the original state.

I'm now somewhat used to it and haven't received treatment for a while, but sometimes when I experience itching, I wonder if I should seek treatment.

When searching for reviews of antifungal medication advertisements, I didn't get a definitive sense that this is the one.

Is there an effective treatment for toe athlete's foot?

Is it best to just consistently visit the dermatologist?
