How can my doctor tell if I have melasma?

Your doctor will be able to tell if you have melasma by looking at your skin. Your doctor may use a special lamp (called a Wood’s lamp) for a closer examination of your skin. In rare cases, your doctor may want to take a very small piece of your skin (biopsy) to make sure that the brown patches are melasma.
