Dyshidrosis: what it is, causes and forms of treatment

Possible causes

The causes of dyshidrosis are not completely known, however, it is more frequent during the summer or in stages of emotional stress, appearing to be related to excessive sweat production, which causes skin irritation, as well as contact with substances with nickel and chromium, detergents, and people affected with atopic dermatitis.

Thus, dyshidrosis is not contagious and therefore there is no danger of transmission, even coming into direct contact with another person’s skin.

What are the signs and symptoms

Dehydrorose can cause the appearance of blisters with a colorless liquid, usually located on the fingers, which can be associated with intense itching, redness of the skin and pain, especially when they are infected. In addition, skin peeling may also occur.

How treatment is done

To treat this problem, the most important is to consult a dermatologist to start the treatment that is usually done with:

  • Creams with corticosteroids, that can be applied to the affected skin, in a thin layer, to help reduce inflammation and dry the blisters, accelerating their disappearance;
  • Immunosuppressive cream, such as tacrolimus or pimecrolimo, which reduce the chances of blisters on the skin, however, because they have effects on the immune system, increase the risk of skin infections;
  • Phototherapy that it is a type of treatment used when creams and ointments do not present results, requiring the use of ultraviolet light to strengthen the skin, preventing it from becoming irritated and making it less susceptible to dyshidrosis.

In the most severe cases, the doctor may recommend making injections of botulinum toxin, also known as botox, to decrease the functioning of sweat glands, reducing excessive sweating which is one of the causes of dyshidrosis.

During treatment, it is also recommended to make compresses or baths of potassium permanganate or 2% boricada water, two to three times a day, until the improvement of lesions, in addition to doing adequate hygiene of the affected region with soap and water, apply moisturizing cream 2 to 3 times a day and avoid coming into contact with irritating substances to the skin , such as cleaning products.
