White Age Spots

White age spots, also known as idiopathic guttate hypomelanosis, are a harmless condition that most often appear on the legs and forearms.

Identification

Idiopathic guttate hypomelanosis are small, teardrop-shaped white spots that appear lighter than the rest of the skin. They range in size from 2 to 5mm.

Types

Idiopathic guttate hypomelanosis most often affects people with light or fair skin. While they predominantly appear on the legs and arms, the spots can also appear on any skin that receives direct sunlight.

Time Frame

White age spots usually begin to appear in people older than 40. They are also more prevalent in women than men.

Causes

Though the cause of idiopathic guttate hypomelanosis is not known, according to DermNet New Zealand, the spots are considered a normal part of the aging process. However, extended sun exposure does a play a role in developing the condition.

Features

The white spots in idiopathic guttate hypomelanosis appear when the skin cells no longer produce pigmentation.
