TRUE
The diagnosis of melasma is fundamentally clinical. However, there are tools to facilitate its recognition: Wood's light and dermoscopy. Through the latter, three patterns can be established: 1) epidermal: brown pigment and regular structured pseudoreticulum 2) dermal: blue-grayish pigment and irregular unstructured pseudoreticulum and 3) mixed: variable shades from brown to blue-gray.
