Idiopathic guttate hypomelanosis
Idiopathic guttate hypomelanosis is a very common acquired disorder that affects women more frequently than men. The disease presents with skin lesions that occur chiefly on sun exposed regions of the skin, suggesting sun exposure may play a role. Similar lesions could be found after the long-term treatment of melasma using 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.
