10 Causes of Lichen Planus
Cause #9: Allergens
The world is full of substances that might be harmful to us. If we do come into contact with such substances, then our bodies will react to try and deal with them. Sometimes, though, the body will recognize harmless substances as being harmful to us, and react as such. These are known as allergens, and they can affect us in different ways.
One possible reaction from an allergen is that they can trigger lichen planus. When trying to find the cause of the condition, doctors will often test you for allergens. Remember that some allergic reactions can be very dangerous, so they should not be taken too lightly.
