Clean 2-in-1 brow and lash boosting serum powered by peptides and vegan keratin that accelerates the appearance of fuller, feathery brows and longer, thicker lashes. Safe for sensitive eyes. Prostaglandin-free.

After 12 weeks of use, 97% saw clinically measured improvement in brow length + lash volume.*

  1. Apply nightly and start with a clean, dry face.
  2. Use one dip of serum + swipe the flatter side of 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 the inner corner, waterline, and bottom lashes (upper application has the lower covered).
  4. Wait 1-2 min for 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 your favorite brow products in the morning for your best brows ever.

    I’ve had thinning brows for many years, but never thought anything would really help. While stocking up on my favorite skincare at Shop Good, I saw Kosas GrowPotion and on a whim, decided to try it. I’m so glad I did. After nightly use for only two months, I actually see hairs growing on the ends of both brows where I haven’t had growth in years! I’m really excited about this and plan to keep on using it to see how much my brows will fill in.
