Every swipe of this clear, lightweight lash serum delivers the brand’s Peptide Complex Technology™, OLAPLEX Bond Building Technology™, hydrating hyaluronic acid, and biotin to your lash line. This powerful formula helps support and sustain the natural growth cycle of your lashes while also helping to condition them. 

Morning and night, use the brush to apply the serum to the skin along your upper lash line on both eyes. Allow it to dry for at least 90 seconds before applying other eye products. There's no need to apply to the lower lash line. Once lashes have reached your desired length, reduce frequency to two to three times per week for maintenance.
