All About Eye Brightening Serum Concentrate is a powerful yet gentle eye serum designed to visibly brighten, depuff, and hydrate the delicate under-eye area. Formulated with potent ingredients like retinoid, vitamin C, and hyaluronic acid, it smooths and revitalises the skin while reducing the appearance of dark circles and puffiness over time. The cooling metal-tip applicator delivers a targeted application while massaging the skin to enhance results and provide an instant radiance boost.
