Some individuals may notice the presence of small blisters or bubbles on their hands and/or feet. These blisters can be bothersome and, in some cases, very itchy.

There can be various causes for these blisters, and one of them is dyshidrosis. Dyshidrosis is a skin disorder characterized by the formation of small fluid-filled blisters on the hands and feet.

To gain insights into this condition, we spoke with a dermatologist.

Causes of Bubbles on the Hands

Bubbles on the hands can result from different factors, including:

  • Dyshidrosis
  • Dermatitis or infection
  • Allergies

Depending on the cause, these blisters may occur alongside symptoms such as:

  • Dry skin
  • Flaking
  • Red dots or pustules

For instance, dermatitis can cause dry skin, cracking, or red spots in the affected area. 

Hand blisters can also appear due to irritation from external agents or the frequent use of harsh handwashing products. 

Allergies to substances like nickel, rubber, perfume, and cosmetic ingredients can also trigger these blisters. However, dyshidrosis is often the underlying cause.

Understanding Dyshidrosis

Dyshidrosis is a skin condition characterized by the formation of small, fluid-filled blisters on the palms of the hands, sides of the fingers, and sometimes the soles of the feet. Key points about dyshidrosis include:

  • The blisters are typically small, around 1 mm in size, and often appear in clusters;
  • Severe cases may lead to the merging of blisters and the formation of larger blisters;
  • The blisters usually last a few weeks and can cause intense itching;
  • Once the blisters dry out, the skin may become dry and flaky;

It’s important to note that dyshidrosis is not contagious but can be painful and bothersome.

The exact cause of dyshidrosis is unknown but may be associated with atopic dermatitis or allergic conditions such as hay fever. Stress could also contribute to its onset, and seasonal eruptions may occur in individuals with nasal allergies.

Managing Dyshidrosis

If you suspect dyshidrosis or have blisters on your hands, it is recommended to undergo a dermatological examination for a proper diagnosis and guidance on appropriate treatments. Treatment options for dyshidrosis may include:

  • Specific products, such as cortisone-based creams;
  • Oral therapies;
  • Other tailored treatments.

Consulting with a dermatologist will help determine the most suitable course of action to alleviate symptoms and promote healing.
