Brow- and lash-boosting serum with a vegan, sensitive-eye-friendly formula powered by peptides, keratin, and hyaluronic acid / .11 oz 

Kosas Grow Potion Fluffy Brow & Lash Boosting Serum is one of those Kosas products that makes you think, “Of course I need this!”

If you’re already a Kosas fan, one of the things you most likely love about their formulas is that they go beyond makeup: their brow pencils and gels feature growth-boosting ingredients, and their mascara features castor oil and peptides to support healthier, fuller lashes.

Grow Potion takes it a step further with a nighttime treatment that’s packed with even more ingredients to maximize both brows and lashes. The hypoallergenic, prostaglandin-free formula features a trio of peptides, vegan keratin, pro-vitamin B5, and hyaluronic acid for a well-rounded solution that accelerates the appearance of fuller brows and longer, thicker lashes. It couldn’t be easier to use, and we love its gentle, sensitive-eye-friendly formula.

Another thing we appreciate? Kosas did a 12-week expert graded study with 29 subjects and found that 28 of them (97%) showed clinically measured improvement in brow length and lash volume. Which, in our view, is really impressive for a formula at a price that’s this gentle — and its thoughtful ingredients will lead to healthier brow and lash hairs, too.

For best results, use Grow Potion every night for 12 weeks (consistency is key, as is patience: the hair growth cycle for brows is somewhere between 3-4 months).

Ophthalmologist tested, safe for sensitive eyes, and prostaglandin-free.

How to Use

Apply nightly on a clean, dry face. For brows, use one dip of serum + swipe the flatter side of applicator to coat the entire brow area. For lashes, 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).
Wait 1-2 min for serum to dry. For the best (fastest) results, don’t apply makeup immediately after application or skip days.
In the morning, follow it up with Brow Pop, Air Brow - Tinted, or Air Brow - Clear for well-groomed brows with additional growth-boosting benefits.
