How to Use
1. Apply nightly and start with a clean, dry face
2. Use one dip of serum + swipe the flatter side of the applicator to coat the entire brow area
3. Use one dip of serum + angle the pointed tip to apply along the top lash line. Avoid inner corner, waterline, and bottom lashes (upper application has the lower covered). 
4. Wait 1-2 min for the serum to dry.  
5. Don't apply makeup immediately after or skip days... that'll just delay your full, fluffy results.
6. Follow up with Brow Pop, Air Brow - Tinted, Air Brow - Clear in the morning for your best brows ever.

Results will vary. Brow results are expected sooner than lashes due to differing hair cycles.
