I'm a firm believer in the power of a good pair of face-framing eyebrows. If shaped and groomed correctly, your brows can make you look much younger and, te lo juro, thinner! Just look at Jennifer Lopez. She's always been fly, but back in the day her brows just didn't do her face any justice. They were just too sparse for her heart-shaped carita. As a result, her face looked broader and, dare I say it, older. However, now that they've grown out and have been groomed, she looks like a completely different, much younger person!

Sofia Vergara's eyebrows BEFORE

Back in the beginning of her career, Sofia sported much thinner brows. Forgive me for saying this, but the woman looks much better now that they've grown out a bit. See what I'm talking about…

Sofia is proof that bigger is better. Her fuller brows help balance her broad smile and big eyes.

Demi's current brow shape is perfect for her face. The slight arch makes make her eyes appear larger, and the new width fits her petite face perfectly.
Christina Aguilera BEFORE

Christina's skinny chola brows are a downright dirty shame! She looks a lot better now that she's grown up and her brows have grown out!

Looks like someone discovered the benefits of brow powder! Personally, I love Urban Decay's Brow Box!
Jessica Alba's eyebrows BEFORE

If I'm being reall honest, Jessica's old brows were just too thin for her broad forehead.

I'm obsessed with Jessica's fuller brows. They take up more space on her forehead, making it appear smaller.
Eva Mendes BEFORE

Even Eva "Best Eyebrows in the Game" Mendes has been guilty of getting a little too pluck happy.

Eva's full brows have become her trademark. May she never lose them, and may her daughter inherit them.
Fergie's eyebrows BEFORE

Nothing G.L.A.M.O.R.O.U.S about these chola-esque brows.
Fergie's eyebrows AFTER

Though they're still thin, Fergie's brows are slightly darker and a bit thicker than they once were, making her look way more put together.
Camilla Belle's eyebrows BEFORE

Camilla's brows have always been bold, but they used to be a little patchy in some places. Watch how her face completely transforms when she fills them in…

Filled in, her brows now look lush and healthy!
Megan Fox's eyebrows BEFORE

Megan's barely there eyebrows leave a lot to be desired.

Her fuller, thicker brows, however, are perhaps the most coveted brows in all of Hollywood.
Angelina Jolie's eyebrows BEFORE

Angelina has always been bold and powerful, but here brows…not so much.

Now THESE are some truly bold & beautiful brows. LOVE!
Shakira's eyebrows BEFORE

I wish I could remember to forget Shaki's old brows. They're so bad, I almost didn't realize she was rocking old school box braids. Almost.

I'm obsessed with Shaki's updated brows. Everything from their length to the height and location of her arch are pure perfection.
