Xanthelasma are small yellowish plaques that develop under the skin on or around the eyelids. They are typically non-itchy and flat, and may vary in size and shape. There are a few synonyms to this condition, including xanthoma, cholesterol deposits, and yellowish eyelid bumps. These growths develop due to the accumulation of cholesterol deposits beneath the skin, and can be symptomatic of high cholesterol levels in the blood. While xanthelasma are generally harmless, they can be a cosmetic concern for some people. Treatment options include surgical removal, chemical peels, and laser therapy, although xanthelasma may return even after treatment.
