We've all been there. Despite your best efforts, you've overplucked, waxed, or threaded your brows to oblivion. What was once full and fluffy is now sparse, or worse, a faint, thin line. Skinny brows are having a renaissance right now, so there's one silver lining. But if your daily look tends to skew more natural, having full arches is ideal. Makeup and brow products can create shape and definition, but it's a temporary fix. Eyebrow serums, on the other hand, can help regrow, thicken, and ultimately re-awaken your brows.

Of course, no one's suggesting you ditch your favorite pencil or tinted gel. Brow serums are designed to promote new growth and nourish your existing brow hairs, meaning they can be used in combination with other brow products. Think of them as part of your skincare routine. Used nightly, they work to boost your brows and, in time, give you a fuller set. Read on to see our top-rated tubes. 

Benefit Cosmetics Hubba Brow Enhancing Serum

Don't let the size of this tube fool you. Benefit's first and only brow serum is packed with conditioning ingredients to promote growth and improve the appearance of your brows. Forget dull and lifeless. This serum adds shine and softens the hair thanks to provitamin B5 and biotin. If that's not enough to entice you, the $58 price tag and help from Benefit's experts should do the trick.

Obagi Nu-Cil Eyebrow Boosting Serum

This serum is a little pricey, coming in at $130, but it's worth every penny. The formula features a proprietary blend that's designed to address thinning and hair loss. That said, it does take some time to see the results. But sticking with it has long-term effects -- think filling in sparse areas and saying goodbye to hair-free patches for good.

Vegamour GRO Brow Serum

If you're familiar with Vegamour's famed hair growth serums, you know just how potent the effects can be. This tiny pink tube packs the same punch, only for your eyebrows. The wand features a unique applicator that swiftly brushes on the product and allows you to coat the hairs from root to tip.

The Ordinary Lash and Brow Growth Serum

If you're looking for a budget-friendly buy, you can't go wrong with The Ordinary's Brow Growth Serum. At just $18, it can't be beaten. The formula volumizes and promotes growth thanks to the multi-peptide complex. Even better? It works just as well on lashes.
