What should you know about treating toe fissures?

A fissure is a narrow split through dry, thickened or inflamed skin. Toes may crack when the barrier loses moisture, when footwear rubs, or when skin is repeatedly exposed to water and irritants. Atopic dermatitis and psoriasis can produce persistent scaling and fissures. Peeling or itching between the toes can also occur with athlete’s foot, which needs a different approach from simple dryness.

Wash with lukewarm water and a gentle cleanser, then pat dry carefully, including between the toes. Apply a bland emollient to the cracked skin several times through the day, especially after washing; avoid packing thick ointment into damp spaces between toes. Choose breathable footwear, change damp socks and reduce friction from tight shoes. Do not pull away loose skin or use acids, blades or harsh antiseptics. A clinician may add treatment for eczema, psoriasis or fungal infection after examining the pattern.

Arrange an assessment when fissures keep reopening, are deep, prevent walking, or occur with marked scaling or itch. Get prompt care for spreading redness, warmth, swelling, pus, fever or rapidly increasing pain. If you have diabetes, poor circulation, reduced sensation or immune problems, seek advice early because a small crack can become harder to manage.

Ask what is causing the fissures, whether fungal testing is needed, which emollient suits your skin, how to protect the cracks while walking, and which warning signs require urgent review.
