What is pityriasis rosea?

Pityriasis rosea is an infectious exanthem most likely caused by the herpes VI-VII viruses on the skin. Unlike other rashes, pityriasis rosea is not contagious and does not require specific treatment. The condition usually lasts an average of one to two months and often disappears on its own, but often recurs even years later.

No. Despite the appearance of patches, pityriasis rosea is caused by a virus and is therefore not a fungal infection.

What does pityriasis rosea look like?

First, a slightly-raised, scaly patch – the ‘herald patch’ – appears. In the following days, it expands into a larger oval shape. In the days and weeks that follow the appearance of the herald patch, numerous other smaller patches form most often on the trunk and arms. Depending on the infection, there may be a small number of inconspicuous patches; or the patches may be numerous and very visible. The itchiness of the patches can also vary from one person to another. Regardless of variables, all patches are pink, hence the name of the disease.

How is pityriasis rosea recognized?

Pityriasis rosea is particular in that it arises from a single, herald patch. The condition is also easily recognisable for the arrangement of the patches, which usually appear in diagonal lines leading away from the trunk, taking on a form similar to a Christmas tree.

How to treat Pityriasis rosea

Throughout the exanthem phase the skin is particularly delicate and irritable therefore it is recommended to:

  • Cleanse with Eudermic Cleansing Base.
  • After washing apply Lenitive Cream to relieve itching and protect the skin.

Avoid the use of cortisone creams as they weaken the skin’s defenses.
