Frequently Asked Questions

How often should I apply the Lash Booster Serum?
Apply a small amount to the lash line 1-2 times daily. Consistency matters here — you’ll start to see lashes looking fuller and more defined with regular use over time.

Before making it part of your daily routine, do a sensitivity test first: apply a small amount to your eyelids three times in one day, or once daily for three consecutive days. If no irritation appears, you’re good to go. Stop use immediately if any irritation develops.
