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.
