What Causes Peeling on the Soles of the Feet?

Peeling of the soles is a common occurrence in daily life. During the dry autumn and winter seasons, it often leads to dryness, cracking, and even pain on the soles. There are many potential causes of sole peeling—aside from inadequate foot care and neglect of foot health, the most common cause is tinea pedis (commonly known as “athlete’s foot”), a fungal infection that requires prompt treatment with appropriate antifungal medications.

What Causes Peeling of the Soles?

1. Excessive Skin Dryness

Autumn air tends to be dry, with low humidity and minimal moisture suspended in the atmosphere. When the soles do not receive sufficient hydration or nourishment, skin cells may undergo necrosis, resulting in peeling. To prevent this, drink plenty of water and consume vegetables and fruits rich in water content. Additionally, soak your feet in warm water before bedtime, then thoroughly dry them and apply a moisturizing lotion.

2. Nutritional Deficiency

Deficiencies in collagen and vitamin E can lead to sole peeling. These nutrients help maintain skin cell viability and elasticity; prolonged deficiency may result in malnutrition, causing skin cell necrosis and extensive shedding of the sole skin. Ensure balanced nutritional intake—consume collagen-rich foods such as pig trotters and chicken skin. Also increase intake of plant oils, nuts, vegetables, and fruits to boost vitamin E levels.

3. Fungal Infection

Tinea pedis is a dermatological condition caused by fungal infection, primarily affecting the superficial layers of the foot skin. Patients with the dry-type variant typically present with dry, rough, thickened, and scaly skin on the soles, accompanied by intense nocturnal pruritus and recurrent episodes.

4. Keratolysis Exfoliativa

This is a dermatological condition affecting the soles, initially manifesting as tiny, rice-grain-sized white spots on the skin surface, which gradually spread outward and spontaneously rupture. Gentle manual peeling reveals thin, paper-like scales; notably, there is no associated pruritus or inflammatory change.

The above outlines the primary causes of sole peeling. To prevent recurrence, maintain good personal hygiene and keep your feet clean. When washing your feet, use lukewarm water—not hot or cold—and dry them thoroughly afterward. Apply vitamin E oil or plant-based oils to retain moisture. Avoid using strongly alkaline soaps or body washes for foot cleansing.
