Easy to use rollerball and refreshing formula marry forming the ultimate power couple. Glide the cooling wand back and forth allowing the rollerball to awaken the eye and soften dark circles on contact. Layer your way to more cooling sensations and coverage. Once the formula is applied dive in there with your finger or a concealer brush to blend the formula on skin and keep stroking your brush and/or finger until you reach the perfect finish. Use everywhere you feel needs a little boost.
