    • Apply nightly.
    • Use flatter side of applicator to coat entire brow area.
    • Angle the pointed tip to apply along top lash line.
    • Avoid applying near inner-eye corner or inside waterline.
    • Start with clean, dry face and wait one to two minutes for serum to dry.
    • Apply a thin layer to the roots of upper lash line.
    • Only use one dip of serum for each brow and lash (a little goes a long way).
    • Don’t apply makeup immediately after.
    • Don’t apply to bottom lashes (upper application takes care of your lower lashes)
    • Don’t skip days—that’ll just delay your visibly full, fluffy results.
