Warning: may cause sudden compliments. This clear, lightweight lash serum is basically a glow-up in a tube. Swipe it on twice a day and let the magic do its thing — softer, happier lashes in 2 weeks, and the “are those extensions?” fullness by week 4. It’s fuss-free, makeup-friendly, and instantly part of your daily vibe. One swipe, major lash energy.
