Cracked Skin

Overview

Cracked skin describes splits or fissures that form when skin becomes too dry, thickened, or inflamed to stretch normally. It happens most often in areas that are exposed, used heavily, or prone to dryness, such as the heels, fingertips, hands, and lips. Cracks can be small and superficial or deep enough to be painful and to bleed.

Most cracked skin is the result of dryness and loss of the natural oils that keep skin flexible. It is more common in cold, dry weather and with frequent hand washing or exposure to harsh chemicals. While usually minor, deep cracks can become painful and create an entry point for infection, especially in people with diabetes or poor circulation.

Common Causes

Cracked skin develops when the skin barrier dries out or breaks down:

• Dry skin (xerosis): The most common cause, often worse in winter and with age.
• Cold, dry weather and low humidity: Pull moisture out of the skin.
• Frequent washing or harsh soaps: Strip away protective oils, especially on the hands.
• Eczema and psoriasis: Inflammatory conditions that leave skin dry, thick, and prone to cracking.
• Pressure and friction: Standing, walking, or footwear that causes thick, cracked heels (calluses).
• Contact with irritants: Chemicals, detergents, and solvents.
• Medical conditions: Diabetes, thyroid problems, and circulation issues can dry the skin and slow healing.
• Athlete's foot: A fungal infection that causes cracking between the toes.

Associated Symptoms

Cracked skin often comes with other signs of dryness or irritation:

• Dry, flaky, or scaly skin
• Itching or tightness
• Redness around the cracks
• Thickened or hardened skin (especially on heels)
• Pain, particularly with movement or pressure
• Bleeding from deeper fissures
• Warmth, swelling, or pus if a crack becomes infected

Redness that spreads, increasing pain, swelling, or drainage suggests the cracked skin has become infected and should be evaluated.

Diagnosis & Evaluation

Cracked skin is usually diagnosed by looking at it, but a clinician may explore the cause if it is severe or recurrent.

• Skin examination: The location, depth, and surrounding skin help identify the cause.
• History: Questions about weather, washing habits, occupation, and skin conditions.
• Fungal testing: If athlete's foot or a fungal cause is suspected.
• Blood tests: Occasionally to check for diabetes, thyroid problems, or other conditions when dryness is widespread or persistent.

Treatment & Management

Most cracked skin improves with consistent moisturizing and protecting the skin:

• Moisturize often: Thick creams or ointments, applied right after washing and at bedtime, help repair the skin barrier. Heel balms with urea or salicylic acid soften thick, cracked heels.
• Gentle cleansing: Use mild, fragrance-free cleansers and lukewarm water rather than hot.
• Protect the skin: Wear gloves for cold weather and when using chemicals or doing wet work.
• Seal deep cracks: Liquid bandage or a protective dressing can help painful fissures heal.
• Treat the cause: Antifungal treatment for athlete's foot, or prescription creams for eczema and psoriasis.
• Humidify: A humidifier adds moisture to dry indoor air.

People with diabetes or poor circulation should inspect their feet daily and treat foot cracks promptly to prevent complications.

Prevention is largely about protecting the skin barrier before cracks form. Moisturizing daily, especially after bathing and during cold or dry weather, keeps skin flexible. Choosing fragrance-free, gentle cleansers, limiting very hot showers, and wearing gloves for cleaning and wet work all reduce the drying and irritation that lead to fissures. For people prone to cracked heels, keeping the heels moisturized, wearing well-fitting shoes, and gently smoothing thick skin before it builds up can stop painful cracks from returning. Consistency over time tends to work better than treating each crack only after it appears.

When to See a Doctor

See a clinician if cracked skin:

• Is deep, painful, or repeatedly bleeds
• Does not heal with regular moisturizing and care
• Shows signs of infection such as spreading redness, warmth, swelling, or pus
• Is widespread or comes with other symptoms suggesting a skin or general health condition

People with diabetes, nerve damage, or poor circulation should seek care early for cracked feet, since these wounds can become serious. Seek prompt care if redness spreads quickly or you develop a fever, which can signal a more serious infection.
