360 Tightening Eye Serum is a lightweight, yet potent eye serum that visibly tightens and firms skin surface in the delicate eye area for a more youthful appearance. The cooling metal tip applicator gently massages skin as it targets puffy eyes to help reduce the appearance of under-eye bags. A combination of caffeine and peptides help revitalize and awaken tired-looking eyes. Patented NIA-114 technology defends against environmental aggressors. With continued use, eye contours look firmer and smoother for a more youthful appearance. Ophthalmologist tested, paraben-free and non-comedogenic.
