If you\u2019ve noticed these spots, you\u2019re not alone. They\u2019re surprisingly common, especially as we age. But what\u00a0are<\/em>\u00a0they? Are they harmless? And is there anything you can do about them?<\/p>\n Let\u2019s explore the most likely causes\u2014and when you might want to mention them to a doctor.<\/p>\n <\/p>\n The medical name is a mouthful, but the condition itself is simple:\u00a0idiopathic guttate hypomelanosis\u00a0(often called IGH).<\/p>\n Let\u2019s break it down:<\/p>\n Idiopathic\u00a0\u2013 The cause isn\u2019t fully understood<\/p>\n<\/li>\n Guttate\u00a0\u2013 Latin for \u201cteardrop-shaped\u201d<\/p>\n<\/li>\n Hypomelanosis\u00a0\u2013 Loss of skin pigment<\/p>\n<\/li>\n<\/ul>\n What it looks like:<\/p>\n Small, flat white spots, usually 1-5mm in size<\/p>\n<\/li>\n Most commonly on sun-exposed areas: shins, forearms, shoulders<\/p>\n<\/li>\n Smooth texture (not scaly or raised)<\/p>\n<\/li>\n More common as we age (often starting after 40)<\/p>\n<\/li>\n<\/ul>\n What causes it? Sun exposure\u00a0over many years (it\u2019s most common on sun-exposed skin)<\/p>\n<\/li>\n Natural aging\u00a0\u2013 the spots become more common as we get older<\/p>\n<\/li>\n Genetics\u00a0\u2013 some people are simply more prone to them<\/p>\n<\/li>\n<\/ul>\n Is it harmful? While IGH is the most common explanation, white spots can sometimes indicate other conditions:<\/p>\n This is a fungal infection caused by yeast that naturally lives on your skin. When it overgrows, it can cause:<\/p>\n White, pink, or tan patches<\/p>\n<\/li>\n Often on the chest, back, and shoulders<\/p>\n<\/li>\n May be slightly scaly<\/p>\n<\/li>\n More noticeable in summer (the yeast prevents tanning)<\/p>\n<\/li>\n<\/ul>\n Treatment:\u00a0Over-the-counter antifungal creams or shampoos often clear it up.<\/p>\n An autoimmune condition where the immune system attacks pigment-producing cells (melanocytes):<\/p>\n Larger, irregular patches of complete pigment loss<\/p>\n<\/li>\n Can appear anywhere on the body<\/p>\n<\/li>\n Often symmetrical (appears on both sides)<\/p>\n<\/li>\n May run in families<\/p>\n<\/li>\n<\/ul>\n Treatment:\u00a0Options include topical steroids, light therapy, and camouflage makeup. A dermatologist can help.<\/p>\n After an injury, rash, or inflammation, some people lose pigment in the affected area:<\/p>\n Follows a pattern of previous skin trauma<\/p>\n<\/li>\n May gradually repigment over time<\/p>\n<\/li>\n Common after eczema flares or minor injuries<\/p>\n<\/li>\n<\/ul>\n Ironically, sun damage can cause both dark spots\u00a0and<\/em>\u00a0white spots.
