The medical term for a crack-like break in the skin is a fissure.
A fissure is a common dermatological term used to describe a thin, linear crack in the skin that is deeper than it is wide. These breaks can extend into the dermis, causing discomfort, pain, and sometimes bleeding.
Understanding Skin Fissures
Fissures are more than just superficial dryness; they represent a significant break in the skin's protective barrier. This can make the affected area vulnerable to infection and prolonged healing.
Causes of Fissures
Several factors can contribute to the development of skin fissures:
- Extreme Dryness (Xerosis): When the skin loses its natural moisture, it becomes less elastic and more prone to cracking, especially in areas subjected to movement or pressure.
- Inflammatory Skin Conditions:
- Eczema (Dermatitis): Conditions like atopic dermatitis can cause severe dryness, redness, and itching, leading to cracks.
- Psoriasis: This chronic autoimmune condition can cause thickened, scaly patches that may crack and bleed.
- Environmental Factors: Exposure to harsh chemicals, cold weather, low humidity, and frequent hand washing without proper moisturization can strip the skin of its oils.
- Mechanical Stress: Repeated friction or pressure on certain areas, such as the heels, can lead to deep cracks.
- Infections: Fungal infections (e.g., athlete's foot) can cause skin maceration and cracking, particularly between the toes.
- Nutritional Deficiencies: In rare cases, certain vitamin deficiencies can impact skin health and integrity.
- Specific Medical Conditions: Some systemic diseases can manifest with skin dryness and fissuring.
Common Locations for Fissures
Fissures can appear on various parts of the body, often in areas where the skin is stretched or subjected to movement:
- Hands and Fingers: Especially on fingertips, knuckles, and between the fingers due to frequent washing and exposure.
- Feet: Deep heel fissures are common, particularly in individuals who are on their feet often or have dry skin. Fissures can also occur between the toes.
- Lips: Chapped lips can develop into fissures, especially at the corners of the mouth (angular cheilitis).
- Around Joints: Areas like elbows and knees can develop fissures if the skin is dry and repeatedly stretched.
- Perianal Area: Anal fissures are common and can be very painful, often related to constipation or hard stools.
Symptoms Associated with Fissures
Fissures typically present with a range of symptoms depending on their depth and location:
- Pain: Often sharp, stinging, or burning, especially upon movement or contact.
- Bleeding: Deeper fissures may bleed, particularly when stretched.
- Itching: Some fissures can be intensely itchy, leading to further irritation.
- Discomfort: A general feeling of tightness or tenderness in the affected area.
Managing and Preventing Fissures
While specific treatment depends on the underlying cause, general strategies for managing and preventing fissures often include:
- Intensive Moisturization: Regular application of thick, emollient moisturizers to keep the skin hydrated and supple. Products containing ingredients like petrolatum, ceramides, or hyaluronic acid can be highly effective.
- Skin Protection: Wearing gloves when exposed to water, chemicals, or cold weather can protect the skin.
- Addressing Underlying Conditions: Treating conditions like eczema, psoriasis, or fungal infections is crucial for long-term relief.
- Avoiding Irritants: Identifying and avoiding triggers that dry out or irritate the skin.
- Hydration: Ensuring adequate fluid intake supports overall skin health.
- Gentle Skin Care: Using mild, fragrance-free cleansers and avoiding harsh scrubbing.

For more detailed information on specific skin conditions or the treatment of fissures, consulting a healthcare professional or reliable sources like the American Academy of Dermatology Association or Mayo Clinic is recommended.
