NEW OLAPLEX PEPTIDE COMPLEX TECHNOLOGY™ - A proprietary peptide blend featuring an OLAPLEX-exclusive peptide that supports the natural growth cycle and lash retention for the look of longer, thicker, stronger, and fuller lashes. HOW IT WORKS:1. Dip the brush once and apply to the skin along the upper lash line on both eyes. Do not wash off.2. Allow to dry for at least 90 seconds before applying other eye products. There's no need to apply to the lower lash line. Use twice daily, AM and PM, on clean, dry skin.
