Please recommend a good dermatology clinic in Iksan.

Please recommend a dermatologist in the Iksan area that is good at allergy care.

My father-in-law has been complaining of itchy skin lately. Every year, when the seasons change, he suffers from allergies that cause his nose to become irritated.

These days, he says his whole body is itchy, but he goes to the local dermatologist, gets a prescription, and applies medicine, but it only works temporarily and doesn't provide a fundamental solution, so he's having a hard time.

If there is a hospital that has treated allergies and seen results, please recommend it.
