OLAPLEX LASHBOND™ Building Serum targets five top lash concerns without unwanted effects: lash length, volume/density, loss/shedding, dry/brittle lashes, and lack of natural lift/curl. The lash serum promotes the look of longer, thicker, stronger, and healthier lashes with next-generation OLAPLEX Peptide Complex Technology, a peptide blend featuring an OLAPLEX-exclusive peptide that supports the natural lash growth cycle and retention to promote the appearance of longer, fuller, denser lashes. 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.
