OLAPLEX LASHBOND™ Building Serum safely targets five top lash concerns without unwanted effects: lash length, volume and density, loss and shedding, dry and brittle lashes, and lack of natural lift and curl with next-generation OLAPLEX Peptide Complex Technology™, a proprietary peptide blend featuring an OLAPLEX-exclusive peptide that supports the natural lash growth cycle and lash retention to promote the appearance of longer, fuller, denser lashes. Exclusive, patented OLAPLEX Bond Building Technology™ helps support the skin barrier at the lash line to support a better environment for lash growth. Hyaluronic Acid and Biotin promote healthy-looking, nourished lashes and reduce the appearance of dry, brittle lashes.
