It absorbs well, and doesn’t bother my eyes. I am starting to see a difference in the quality of my lashes and brows.

How to Use

Apply nightly and start with a clean, dry face.
Use one dip of serum + swipe the flatter side of applicator to coat the entire brow area.
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.
Don’t apply makeup immediately after or skip days…that’ll just delay your full, fluffy results.
Follow up with Brow Pop, Air Brow - Tinted, Air Brow - Clear in the morning for your best brows ever.

GrowPotion Tonight, Brow Team Tomorrow

When we launched Air Brow - Clear, our community was so impressed by the improved appearance of their natural brows, they started to apply it to their brows and lashes overnight.

Sheena wanted to create a product formulated specifically to wear overnight (without the definition and hold of the brow gel), so we added 6x more powerful and effective hair-boosting actives in a concentrated serum to create GrowPotion.

Now introducing the nighttime treatment partner to your daytime brow + lash routine.

Wow!
I wish I had taken before and after photos to better illustrate how effective this product is, but I am really happy with it. Before using, my lashes were almost nonexistent. Short and sparse and curling or the large variety of different mascaras were not helpful. It took some time and while my lashes are still a little thin, the length and volume has really been incredible. Consistency is key with this product, but for me, the results speak for themselves. The formula is non irritating and easy to apply. Yes it does leave a bit of residue when I wake in the morning, but it’s easily removed. I can’t say enough good things about it. I love my new lashes!

Love my new brows and lashes
I’ve used quite a few products to grow my brows and eyelashes. This brand works great. After 1 month, my lashes are so long that I don’t need mascara. Highly recommend this product

GREAT!
I’ve been using this since August and it’s made a difference! I personally noticed a difference within a WEEK but everyone’s different. Here I am in November and still loving this product. My lashes were long-ish to begin with, but now they are curly and others have noticed it too! You can tell by the darkness of my lash line. I’ve recommended this to so many others, but remember PATIENCE and CONSISTENCY IS KEY.

significant volume improvement
my eyelashes have always been really thin and sparseish and my brows have been overplucked in the past with some patches that have grown in but are thin. i have been using this for about a month now and i love it. my eyelashes are significantly longer (pretty shocked by that tbh) and my brow patches are showing realistic growth. wish i took before and afters but oh well. worked for me! would recommend absolutely.

My wife and I have been using this for a month and have both seen tremendous growth and thickening of our eyebrows.
I wish they made one for my receding hairline lol
