Frequently Asked Questions
You've got questions, we've got answers
When will I see results?
Results will vary by individual, but based on an expert graded study, 97% of subjects saw clinically measured improvement in brow length + lash volume in 12 weeks.
* Brow results are expected sooner than lashes due to differing hair cycles.

Will this irritate my eyes?

If you experience irritation, please discontinue use and contact us.

After! Start with a clean, dry face and wait 1-2 min for serum to dry. Apply a thin layer to the root of your upper lash line. Use only use one dip of serum for each brow and lash (little goes a long way!) Stay consistent and apply every day (you can do it).
