Definition

Idiopathic Guttate Hypomelanosis is a long-term skin condition that causes small, white, porcelain-like spots to appear on the skin, usually on the shins and forearms. These spots are typically 2-5mm in diameter and are caused by a reduction in melanin, the pigment that gives skin its color.

Causes

The exact cause of Idiopathic Guttate Hypomelanosis is unknown, hence the term "idiopathic". However, it is believed to be related to aging and sun exposure.

Treatment

There is no cure for Idiopathic Guttate Hypomelanosis, but treatments can help to improve the appearance of the skin. These may include topical retinoids, laser therapy, and microdermabrasion.
