This is a triple-action eye serum that brightens, firms and tightens the skin around your eyes. The serum is formulated with Hawaiian sea algae, which provides essential hydration, and patented peptides that help brighten under-eye circles. Additionally, the serum contains castor oil and algae. I love this eye cream, it has a lightweight, non-greasy, and gentle creamy texture. It is absorbed quickly into the skin. It has helped to brighten and smooth my under-eye area.
