After using each night for just a couple of weeks I can actually see new growth and my wild looking brows are now tame and in place.

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

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.
