Introduction
Peeling of the soles without itching or pain may result from physiological factors such as dry skin or physical damage, or pathological conditions such as chronic hyperkeratotic tinea pedis or exfoliative keratolysis. Treatment options, including general management and medication, should be selected according to the underlying cause. Avoid consuming irritating foods or those that may trigger allergies; irritants include spicy, raw, cold, or greasy foods.
Peeling of the soles without itching or pain may be caused by physiological factors such as dry skin or physical damage, or pathological conditions such as chronic hyperkeratotic squamous tinea pedis or keratolysis exfoliativa. Depending on the underlying cause, general management or medical treatment may be selected.
I. Physiological Factors
1. Dry Skin
Various factors such as excessive washing with hot water, exposure to wind and sun, or aging can lead to dryness of the sole skin, resulting in abnormal shedding of the stratum corneum and peeling. In severe cases, skin fissures may develop. After routine cleansing, apply moisturizing skincare products locally, such as glycerin for skin care or medical-grade petroleum jelly.
2. Physical Damage
Hard shoe soles or prolonged walking can cause physical trauma to the stratum corneum of the foot, leading to peeling. For mild symptoms, wearing soft, comfortable shoes and reducing walking activity may help. For more noticeable symptoms, topical treatments such as urea cream can be applied to improve the condition.
II. Pathological Factors
1. Chronic Hyperkeratotic Squamous Tinea Pedis
This condition is caused by dermatophyte infection. Commonly used medications include terbinafine and itraconazole. If secondary bacterial infection occurs, antibiotics may be used in combination, along with topical application of 0.1% ethacridine lotion.
2. Keratolysis Exfoliativa
This condition is characterized by superficial scaling on the palms and soles. The exact cause is unknown but may be associated with fungal infection, hyperhidrosis, or genetic factors. Symptoms often resolve spontaneously when the weather becomes cooler. Maintain clean and hygienic skin care to prevent skin breaks. Consuming fruits and vegetables rich in vitamins may support recovery.
It is recommended to avoid consuming irritating foods or those that may trigger allergies, including spicy, raw, cold, or greasy foods such as chili peppers, raw onions, mutton, seafood, and hot pot. Choose well-ventilated shoes and socks, and keep feet clean and dry. Take precautions in public places and avoid sharing footwear, socks, or towels. Maintain good personal hygiene by frequently changing and washing socks. When washing socks, consider scalding them with boiling water or using a laundry disinfectant, then drying them in direct sunlight.
