(COSMO) - There’s a growing trend of thicker, fuller eyebrows that everybody wants. Gone are the days of plucking and threading to the point of no return. 

But just because a fuller brow is desired, it doesn’t mean everyone can have it. Many of us have thinner eyebrows that need that accentuation. That’s where Eyebrow Growth Serums can help. By using a growth serum once a day, you can help regrow and strengthen your brows for a healthier and fuller look.  

However, with so many eyebrow growth serums to choose from, how do you know which one is right for you? Well, you’re in luck, our team of reviewers and make-up artists have created a list of the FIVE best eyebrow growth serums on the market today… Let’s get started.

Liaison has it all, a good value, safe ingredients, and (brace yourself) it works! We tried Liaison after we found the 50% off code SECRET50. We gave it a six-week trial and found our journalist Stephanie Marianne’s eyebrows to have a fuller, longer look. The ingredients are natural and don’t cause irritation or burning, and the instructions are straight forward and simple. It’s really the best of everything packed into one product. Effectiveness, safety, and value all rolled into one. 

Effectiveness: 89%

Safety: 70%

Price: $$$$

Overall Value: B+

Latisse is probably the most well-known eyebrow serum on the market. It’s definitely one of the most expensive. For its effectiveness, it certainly has a hefty price tag, especially with results often being mixed. Some women claim it works wonders for their eyelashes, while many are left with lackluster results.

Effectiveness: 51%

Safety: 98%

Price: $$$

Overall Value: B-

WooLash has garnered some great press for its natural ingredients and claims to use healthier supplements to improve your eyelash and eyebrow growth. But does it work? Not so much. There’s about a 51% effectiveness rate, which means you’re flipping a coin on your lashes. At the very least, it won’t burn your skin, you just won’t have eyebrows people like looking at. 

Effectiveness: 33%

Safety: 90%

Price: $

Overall Value: C

Kate Blanc provides a well-concentrated castor oil (yes, that stuff you sometimes cook with). It’s all-natural ingredients make it safe, and there’s certainly no harm in using it. It can help keep brows healthy, but we haven’t seen extremely great results. If you’re working on a budget, there’s no reason not to use castor oil, just don’t expect miracles. 

Effectiveness: 5%

Safety: 10%

The terrible Amazon reviews might be a tip-off, but if you took the risk you’d find unhealthy chemical ingredients, ineffective results, and a quarter-filled bottle that really makes you wonder what you’re paying for. BEWARE, it’s not worth it. 

While we feel we recommended some great eyebrow growth serums for fuller, darker brows, we believe Liaison's product was the top choice. We wanted to talk further with our investigative reporter Stephanie Marianne on how Liaison Brow Bond worked for her. Stephanie tells the story.

Personally, I never believed in the effectiveness of eyebrow serums. There’s a lot of brands out there claiming they work, but most don’t. I’ve had too many friends tricked into buying serums just to find out it’s a waste of money. So I’ve avoided it at all costs. 

But then my best friend, who I trust with my life, swore by Liaison’s Lash Bond. She said she's never used a product that worked so well with such simple instructions. She had been using the Brow Bond every night before bed and said it worked within 4 weeks. I, of course, didn’t believe her. But then she showed me her before and after photos and I was stunned. 

Week by week, I could see her eyebrows getting healthier and longer. I begged her to let me borrow her Lash Bond. Instead, she gave me a secret 50% off code, SECRET50, and I ordered two bottles immediately. 

I received the package within two days and started using it that night. The application is very simple, a small amount across your eyebrows before you sleep. It feels like placing water on your brow. Of course, I woke up the next day expecting a miracle… but alas, it takes longer than that to see results. 

So while I waited, I looked into the science of Liaison’s Growth Bond Formula. I wanted to know how it worked, and what it was aiming to do with my eyebrows…

Step 1: When you apply Liaison, a fresh supply of oxygen and citric acid work away at eyebrow hair waste, releasing it through your pores to be washed away and clearing the way for nutrients.

Step 2: The specialized mixture, including purified water and hyaluronic acid, activates internal peptides and gains access to follicles to prepare for bold growth.

Step 3: Polypeptides travel deep into your roots, supplying follicles with essential proteins while you show off your amazing brows.

Step 4: Refreshed brows and follicles continue to receive the optimal oxygen, blood flow, and dose of nutrients needed to keep brows healthy and strong.

After about 3 weeks is when I began to notice the color of my brows getting darker. 4 weeks and I noticed I didn’t have to apply as much of the eyebrow blade pen I use for shading. By week 6, it was as if I was a totally different woman.

Since then, I’ve continued to apply and my brows have only grown thicker and healthier thanks to Liaison Brow Bond.
