Our formula
We made OSMI Lash Serum with one goal: a lash serum that actually delivers on its promise. Peptides, biotin and pro-vitamin B5 – no hormones, no prostaglandins, no parabens. One stroke a night, and your lashes do the rest.

Your lashes follow a natural growth cycle. Keep using the serum to keep the look; if you stop, lashes gradually return to how they looked before over a few months.
One tube (3 ml) lasts about 3 months with daily use on both upper lash lines.
Once a day, on clean and dry skin: one thin stroke along the root of the upper lashes, like eyeliner. Let it dry for 2–3 minutes.
Most people notice more conditioned lashes after 2–4 weeks and the full look after about 12 weeks of daily use.
Rinse with lukewarm water. Apply only to the upper lash line and avoid the eye itself.
