Pityriasis rosea (Gibert’s disease) is a common benign skin condition characterized by pink patches with mild scaling. It usually begins with a single larger patch, followed by multiple smaller lesions spreading across the body.
The main symptoms include oval pink patches, sometimes with itching and characteristic fine scaling at the edges. The condition is not contagious: it is not transmitted through contact and is not caused by a fungal infection.
Pityriasis rosea typically resolves on its own within 4–8 weeks, sometimes longer. In most cases, the skin heals completely without leaving marks.
What to do if you suspect it
If you notice pink patches on the skin, especially after a recent cold or viral illness, it is important to consult a dermatologist.
The first step is a medical examination. This is necessary to distinguish pityriasis rosea from other conditions that may look similar, such as fungal infections or other rashes.
In atypical or prolonged cases, a doctor may recommend additional tests.
It is important not to use harsh ointments, alcohol-based solutions, or irritating treatments, as these may worsen the rash and slow skin recovery.
How the disease looks
The condition usually starts with a single large pink patch called the “herald patch.” It is round or oval and may show mild scaling.
After several days or weeks, smaller oval patches appear, most often on the trunk, shoulders, and thighs.
A characteristic feature is a thin ring-like scale at the edge of the lesions, sometimes described as a “collarette” of scale.
The number, size, and severity of lesions can vary between individuals.

Main symptoms
The main symptom is the appearance of pink patches with mild scaling.
Other possible symptoms include:
- moderate itching
- dry skin sensation
- worsening itch with heat, friction, or stress
General health is usually not affected or only minimally impacted.
Causes of the disease
The exact cause of pityriasis rosea is not fully understood.
It is thought to be related to an immune response following a viral infection. In simple terms, the skin temporarily reacts to changes occurring in the body.
Possible triggering factors include:
- recent cold or viral infection
- stress
- reduced immune function
- hormonal changes
- rarely, reaction to certain medications
These are not direct causes but may trigger the condition.
How the disease develops
After a triggering event, the immune system becomes activated and causes an inflammatory reaction in the skin.
This leads to the appearance of characteristic patches and mild scaling. The skin barrier may temporarily become more sensitive to external irritants.
Over time, inflammation gradually resolves, and the skin heals naturally.
Forms and types
Most commonly, the classic form occurs with a herald patch followed by widespread lesions.
Atypical variants exist but are less common and may differ in appearance or distribution.
When to see a doctor
See a dermatologist if:
- the rash spreads quickly or looks unusual
- the rash lasts longer than 8–12 weeks
- there is significant itching or discomfort
- there is uncertainty about the diagnosis
- symptoms worsen or new signs appear
Medical evaluation helps rule out other conditions and provides guidance for skin care.
Treatment
In most cases, no specific treatment is required, as the condition resolves on its own.
The main goal is to reduce discomfort and support skin healing.
If needed, treatments may include anti-itch or anti-inflammatory agents, as well as gentle moisturizers.
Recommended care:
- regular skin hydration
- use of mild cleansing products
- avoidance of heat, hot baths, and skin friction
In rare cases with severe or prolonged symptoms, a doctor may prescribe additional therapies.
Important: all medications should be used only under medical supervision.
