Leucoderma is a skin disease where skin loses its color or pigment, leading to white patches on skin. It is not a serious disease. It can affect children and adults. It occurs due to one or both of the following processes in the body:

1. Destruction of Melanin

2. Deficient Formation of Melanin

The factors which lead to above two processes are not fully understood, but they are a mix of genetic, auto-immune, hormonal, allergic and stress related, besides some chemicals destroying skin pigment directly. Usually, there are multiple factors play combined roles to develop it.
