The condition presents with skin lesions that occur primarily on sun‑exposed areas, suggesting that sun exposure may play a role. Similar lesions can appear after long‑term treatment of melasma with the QS1064 laser. No specific treatment is required.

Idiopathic guttate hypomelanosis (IGH) is a benign, typically asymptomatic, leukodermic dermatosis of unclear etiology that is classically seen in elderly, fair-skinned individuals, and often goes unrecognized or undiagnosed. Occasionally, IGH is aesthetically displeasing. However, it is not a dangerous process. Once present, lesions do not remit.
