Oh, what would we do without our eyebrow gels and eyelash serums? Not only have they blessed us with noticeably longer lashes and snatched brows, but the products are also way more budget-friendly than getting extensions or other treatments done on the regs. And now, Kosas' newest launch just made our brow and lash game even better with their GrowPotion, a two-in-one serum that gives you fluffier brows and thicker lashes at lightning speed, for $48 a pop.

The best part? Buyers say this stuff really works. Just see the before and after photos for yourself.

The product is formulated with peptides, vegan keratin, provitamin B5 and hyaluronic acid. Together, these ingredients nourish, strengthen and condition your brows and lashes, revealing longer and thicker hairs within 12 weeks (when you apply a thin coat each morning).

As one fan shares, "I have been looking for something that will help my eyebrows thicken, and this product [does] not disappoint. [Plus,] the angled sponge brush allows for easy application to lashes and brows."

Kosas Newest GrowPotion Lash and Brow Boosting Serum

That's right, folks. The applicator brush is similar to a lipgloss wand, so all you have to do is swipe a thin layer onto your entire brow (using the flatter side) and then use the pointed tip to apply the serum to the upper lash line. (The brand advises against applying it to your bottom lash line since the top one will transfer when you blink.)

Oh, and did we mention GrowPotion is vegan, hypoallergenic, prostaglandin-free and ophthalmologist tested for sensitive eyes? Um, that's all we needed to hear.
