Scaly keratosis pedis is caused by superficial fungal infections and is characterized by flaking, keratosis thickening, and rough, dry, cracked skin. For treatment, ointments such as compound benzoic acid ointment or 10% salicylic acid ointment are used; for keratosis thickening with visible chapping, 30%-40% urea ointment can be used to seal the package, and then antifungal medications such as terbinafine ointment or bifenazole cream can be applied twice a day after the keratosis has thinned, and treatment needs to be adhered to for more than four weeks. For recalcitrant cases, itraconazole or terbinafine or fluconazole can be used as oral treatment. Combined with bacterial infection, you can combine antibiotic treatment, and you can also try herbal foot soak treatment. After the foot fungus is cured, it is important to expose the shoes and socks to the sun frequently, and if other members of the family have foot fungus, they need to be treated at the same time.
