Cracks on the Fingers: Causes and Treatment
Dry skin on the hands usually feels tight and rough. However, when cracks develop on the fingers, the problem becomes noticeable with every movement: the skin hurts when bending the fingers, stings when exposed to water or other irritants, and may even bleed. Moreover, this condition may indicate more serious underlying health issues that need to be addressed. Why does the skin on the hands start to crack, how can you help it heal, and when should you consult a dermatologist? The specialists at LeoDerm Clinic explain.
Why Does the Skin on the Fingers Crack?
The skin cracks when it loses moisture and elasticity. As a result, it can no longer stretch sufficiently during movement and begins to split. Cracks most commonly develop around the fingernails, on the fingertips, and along the creases of the fingers. Excessive dryness may be caused by external factors, but in some cases, cracks are a symptom of an underlying skin condition.
Common causes of peeling skin and cracks on the fingers include:
- frequent handwashing and contact with cleaning products;
- exposure to cold air and low humidity;
- inadequate skin care and moisturizing;
- dermatitis, including contact, irritant, occupational, and allergic dermatitis;
- skin conditions such as eczema and psoriasis;
- fungal skin infections;
- nutritional deficiencies.
If the skin on your fingers keeps peeling and conventional skin care does not help, or if new cracks appear, existing ones become deeper, or they fail to heal for an extended period, you should consult a dermatologist to identify the underlying cause and determine the appropriate treatment.
Cracks on the Fingers That Bleed: What Should You Do?
A crack in the skin of a finger can cause not only physical discomfort and cosmetic concerns but also increase the risk of infection. If a crack is bleeding, follow these first-aid steps:
- gently apply pressure to the affected area with a clean cloth or gauze pad;
- rinse the wound with water;
- cover it with an adhesive bandage or sterile dressing.
Protect the damaged skin from cleaning products and further injury.
Do not delay consulting a dermatologist. A specialist will assess the condition of your skin and, if necessary, recommend further evaluation or treatment.
What Should You Apply to Cracks on the Fingers?
Once the skin on the fingers has cracked, regular hand care may no longer be sufficient. It is important to help the damaged areas heal and identify the underlying cause of the cracks. A dermatologist can recommend the most appropriate products after examining your skin and determining the cause of the problem. Depending on the skin’s condition, a specialist may recommend different options:
- Intensive moisturizing creams to help relieve dryness, such as Eucerin AtopiControl Calming Hand Cream or CeraVe Reparative Hand Cream.
- Repairing creams for damaged skin, such as Rilastil Xerolact Repairing Hand Cream or Lacera ProRepair Cream.
- Protective ointments for particularly dry and cracked areas, including Eucerin Aquaphor Repairing Ointment.
It is also worth replacing harsh soaps with a gentle cleansing product. Suitable options include products from the A-DERMA range or Eucerin pH5 Soap-Free Cleansing Bar. If the cracks are caused by a fungal infection, moisturizing creams alone will not be sufficient. A doctor will select the appropriate dermatological treatment.
Why Do Cracks on the Fingers Keep Coming Back?
When the skin on the fingers repeatedly splits after healing and the condition becomes chronic, it is worth looking deeper into the underlying cause. A dermatologist can help address the problem and recommend preventive measures. However, if the cracks keep returning despite proper skin care, further evaluation by another specialist may be necessary:
- fungal infections or psoriasis can resemble ordinary dry skin but require a different approach to treatment. To confirm the diagnosis, a dermatologist may recommend further tests, including a fungal test if necessary;
- Thyroid disorders or diabetes can worsen skin dryness. If either condition is suspected, a family doctor may recommend blood tests and, if needed, refer the patient to an endocrinologist;
- nutritional deficiencies can affect skin health and wound healing. However, cracks on the fingers alone do not indicate a deficiency. A family doctor will determine whether tests are necessary based on other symptoms.
Identifying the underlying cause helps ensure effective treatment and reduces the risk of the cracks recurring. If a crack on your finger is causing concern, pain, or discomfort, book a consultation with a dermatologist at LeoDerm Clinic. A specialist will help identify the cause of the problem and develop an appropriate treatment plan.
