Lichen ruber planus is a chronic skin disease developed once the cells in the skin or mucus are destroyed by our immune system. It affects the skin, nails, mucous membranes, and hair, which results in inflammation.
Typically, lichen planus shows as an irritating, purple patch in the skin that grows over many weeks. It also affects areas covered by mucous membrane, namely the mouth and vagina, causing lacy white spots.
Furthermore, lichen planus affects around 1 in every 100 individuals. Male and females in their middle ages are more prone to get this kind of disease.
