This serum is specifically formulated to help your lashes and brows grow. It is rich in castor oil to help nourish lashes and brows, while schisandra extract strengthens them. The formula also contains a blend of peptides to prevent brows and lashes falling out and help them appear fuller. The serum’s light, watery texture doesn’t weigh lashes down or leave brows hard or crusty. Each day, lashes and brows appear longer and thicker, revealing their beauty. Ophthalmologically tested.
