Aloe Vera deeply calms and hydrates the area while Hylauronic Acid instantly plumps fine lines. The cold roller ball assists with puffiness and the rolling motion encourages lymph drainage to reduce dark circles. The skin around the eye area is very thin and delicate. The roller system is designed to disperse a really small amount of product evenly across the area to allow maximum absorption and reduce puffiness. Safe for milia-prone skin.
