Luminizer is pretty much the same as an illuminator and as a term in the world of makeup is used far less often than illuminator. However, some makeup artists consider lumnizers as similar to illuminators only with a touch more of obvious shine.
Furthermore, depending on the consistency of the product, color and the application technique these types of products can be used interchangeably so some highlighters can be used as an overall face illuminator and some illuminators can be used as a highlighter."
