The condition causes thinning of the affected areas, hence it can tear and bruise easily. It is most common with post-menopausal women.
What is Lichen Planus?
Lichen planus is also a skin disorder that often affects the skin and in other cases, inside the mouth and vagina. Lichen planus comes in different forms, which are basically identified based on the area affected.
