Patients should wear appropriate shoes and socks, avoid standing or walking for a long time; you can soak your feet in hot water to soften the keratin and then remove it with a knife, or use salicylic acid and other exfoliators.
2. Tinea pedis: fungal infections such as Candida albicans, Trichophyton rubrum, and Trichophyton mustelii destroy the skin stratum corneum cells, resulting in changes such as hyperkeratosis, hyperplasia, and desquamation of the skin, and so on, so that the above symptoms appear. It can be treated with topical antifungal drugs such as ketoconazole, econazole and terbinafine.
3. Palmoplantar keratosis: hereditary and acquired, manifested as progressive thickening and hardening of the skin of the toes, accompanied by keratinization and desquamation, usually without itching symptoms. Urea ointment, salicylic acid ointment, retinoic acid ointment and other keratolytic drugs can be applied; oral retinoic acid drugs can also be taken.
