Dead skin on the feet can be caused by eczema, tinea pedis, or calluses, etc. If there is a small amount of dead skin, there is usually no need to treat it. When there is a large amount of dead skin, it can be removed by medication, mechanical grinding and physical therapy. 1. Medication. Tinea pedis and eczema are the main causes of dead skin on the feet. Targeted treatment with antifungal (naftifine ketoconazole cream) and anti-allergic medications (dinexidine cream) can improve the symptoms of dead skin on the feet. 2. Mechanical grinding. Skin has a normal metabolic process, usually there will also be a small amount of dead skin on the surface of the skin, this situation does not need to be treated. When the number of dead skin is large, the skin can be smoothed by mechanical abrasion. 3. Physical therapy. Callus can lead to a large amount of localized dead skin, which can be removed by cryotherapy and laser treatment. As different people have different requirements for skin, you can ask your doctor to choose the appropriate method according to your clinical needs, and do not blindly deal with it on your own, so as to avoid delaying your condition.
