Please recommend a dermatologist in Gwangju that is good at treating athlete's foot.

As summer approaches, one thing always comes to mind: athlete's foot on my left foot.

I have athlete's foot, which causes dead skin cells to form and peel off, but no matter how much athlete's foot medicine I buy and apply, it doesn't get better...ㅠㅠ

Nowadays, it is transmitted through the big toenails, and the shape of the toenails changes into an ugly ingrown toenail.

My toenails have turned yellow too...ㅠㅠ I'm so upset...ㅠㅠ

It's not ticklish or smelly or anything... but I keep getting worried...ㅠㅠ

If there is a dermatologist that is good at treating athlete's foot, please recommend one....^^
