The Roll-on Under Eye Serum is a luxurious under-eye spa designed to refresh and rejuvenate. A gentle glide of the roll-on serum applicator deeply hydrates the sensitive under eye skin, leaving it smooth and moisturized. The thoughtfully crafted under eye formulation uses the power of moisture magnet squalane, skin smoother phyto-retinol (a natural plant-based alternative to retinol), and blood circulation booster caffeine.
