This clear, lightweight, eyelash-enhancing serum promotes the appearance of thicker, longer, stronger, full-volume lashes and contains:

OLAPLEX Peptide Complex Technology®- a proprietary blend of peptides, including an OLAPLEX®-exclusive peptide that supports the look of longer, thicker, stronger, and fuller lashes. Our exclusive OLAPLEX Bond Building Technology® supports the skin barrier at the lash line. Hyaluronic Acid promotes hydrated, healthy-looking lashes and reduces the appearance and feel of dry, brittle lashes.

We recommend applying this product 2x a day. This recommendation is based on the protocol for our clinical studies and provides optimal efficiency. For the product to work its best, we recommend consistent application for stronger results.

In a 12-week clinical trial of 33 people using LASHBOND® Building Serum, participants reported the following after four weeks:

94% experienced more voluminous-looking lashes
97% reported improvement in the appearance of denser lashes
97% reported improvement in the appearance of longer lashes
100% reported improvement in the appearance of thicker lashes*

*Results may vary. As reported by participants after 4 weeks in a consumer perception clinical study of 33 subjects with 2x daily use.

We clinically tested it for use on eyelashes only and recommend following the intended product usage and instructions. In addition, we recommend only applying the product directly to the upper lash line, as the product migrates on its own through the action of blinking, so it's best not to apply directly on the lower lash line.

Some of our clinical study participants saw positive results as early as two weeks.
