What Are the Symptoms of Lichenification?
The first sign of lichenification ishyperpigmentation,which is when theskinbecomes darker than the skin around it.
Types of Lichenification
The two types of lichenification are:
What Causes Lichenification?
Primary lichenification develops from excessive itching, scratching, or rubbing.
This extreme itch isnt associated with any underlying physical cause and is referred to as neurodermatitis orlichen simplex chronicus.
InanxietyandOCD, the itchiness and development of lichenification are often associated with the itch-scratch-itch cycle.
This cycle, which can be incredibly difficult to avoid, starts with a minor itch.
Where Does Lichenification Appear on the Skin?
Primary lichenification typically can be found on the scalp, neck, arms, and genitals.
There is little research available on what types of medications cause lichenification.
How Is Lichenification Treated?
Lichenification has many treatment options, depending on the cause.
Anti-itch creams are used short term to relieve the symptom.
For secondary lichenification, therapy is dependent on the cause.
The treatments mentioned above can also be used for secondary lichenification.
Can Lichenification Be Cured?
Lichenification is often associated with incurable disorders.
However, those same disorders are often highly manageable with the right therapy and approach.
Because of this, lichenification can be effectively managed with proper treatment.
Permanent scarring and hyperpigmentation are also possible but dont happen in all cases of lichenification.
Are There Tests to Diagnose the Cause of Lichenification?
A physical exam of the skin is often enough for a healthcare provider to determine if lichenification is present.
Skin biopsies are the most common tests healthcare providers use when diagnosing the cause of lichenification.
Summary
Lichenification can develop idiopathically because of excessive itch or secondary to underlying health disorders.
It presents as a thickened layer of skin that’s darker than the skin around it.
Treating lichenification can be a simple process once the cause has been identified.
If you experience any signs of lichenification, see a healthcare provider.
They will determine the cause and develop an effective treatment plan to clear up the symptom.
