👉 Purpurite is a condition characterized by white patches on skin that develop in response to exposure to certain irritants, such as dust or pollen. These patches can be found on the face, nose, throat, and mouth. The cause of purpurite is not fully understood but it may involve an allergic reaction or an immune system response to a particular allergen. It's important for people with purpurite to avoid exposure to irritants and seek medical attention if symptoms persist or worsen
