How to use
Clean
Clean and dry the eye area and remove any eye makeup.
Apply
Wipe excess serum off the brush, then draw one thin line along the base of your upper lashes.
Overnight
Let it absorb for 2–3 minutes. Use once a day, ideally right before bed.
Tip
Wear contact lenses? Take them out first and wait until the serum has absorbed before putting them back in.
Avoid direct contact with the eyes. Stop use if irritation occurs.
Our story
We almost launched a lash serum like everyone else's. Then we read the ingredient lists.
So we built ours differently: two well-known peptides in a gentle, fragrance-free gel, with every ingredient on the label. It won't work overnight. It's made to be used with patience.
Our promise
Try it for 60 days.
Use it every evening. If you don't love your lashes, we'll refund you, even on an opened tube.
