Lumedia is manufactured by Bremenn Labs, the same company that produces Hylexin, the popular treatment for dark under-eye circles. Like its sister product, Lumedia is also designed to fight a common sign of aging: liver spots. Also known as hyperpigmentation, these spots are usually caused by sun damage and commonly appear on the hands and arms, which tend to get the most exposure. However, according to the manufacturer, this product may be used all over the body, including the face.
