A lightweight nightly serum formulated to support the appearance of longer, fuller-looking lashes and brows over time. Apply with the built-in precision brush along the lash line before bed as part of your evening routine. Free from harsh chemicals and gentle enough for daily use, even on sensitive eyes. Most customers begin noticing a visible difference in lash fullness within 4-6 weeks of consistent use. Pairs perfectly with our LED Mask for a complete nightly ritual. A small step that makes a noticeably bigger difference every time you look in the mirror.
