Xanthelasma is a type of skin lesion that usually appears around the inner corners of the upper or lower eyelids. It is often associated with deposits of cholesterol or other lipids within the skin. Some people develop these patches even when their cholesterol levels are normal, while others may have an underlying lipid imbalance. Although xanthelasma is generally not harmful, many people choose to have it removed for cosmetic reasons. A dermatologist can examine the affected area and determine whether the appearance is consistent with xanthelasma before recommending treatment.
