Isopropyl cloprostenate is a synthetic compound otherwise referred to as a prostaglandin analog. It is required, by the FDA, to be labeled as a drug by the FDA. The trouble is that this ingredient, while helpful, can cause serious issues if you’re allergic or use incorrectly. The chemical can cause serious side effects including eye irritation, eye inflammation, eye redness, white cysts, and macular edema. The worst cases report the user’s eyes changing colors!

“I used a certain serum before I knew it had isopropyl cloprostenate, and one day I woke up and I couldn’t even open my eyes. It hurt so bad. Thank god I got to the doctor in time!”

-Cindy M., Texas


Triethanolamine can help balance the pH of your lashes for better growth while also helping keep some of the other ingredients as a liquid. However, it’s an ingredient that should not be considered for longer use. So when using a growth serum for long periods of time, it can have harmful effects. Triethanolamine is known to affect the immune system and is a respiratory toxicant. If you have sensitive skin, it’s even more dangerous.

“I was using a serum that seemed to be working really well, but three weeks in I started feeling really ill. Then, my eyes kept getting really red, like I had just run through a field of wildflowers and my allergies were going crazy! I didn’t know what it was, so I stopped using my serum. That’s when it finally went away.” -Tina G., Iowa


Surprisingly, boric acid is used a lot in eyelash serums, and has shown positive results. Unfortunately boric acid has been linked to endocrine disruption. The ingredients can alter your hormone levels in a way that makes your body, including your eyes, susceptible to tumors, cancer, and birth defects.

“I never thought boric acid would be an issue. I had some eye irritation and went to the doctor for it and I had started to develop a small tumor behind my eye! Thankfully, we caught it before it became too serious.”

Sophie Z., New York


We wanted to talk further with our investigative reporter Stephanie Marianne who helped find the most effective eyelash serum with the safest ingredients, Liaison Lash Bond, and how it worked for her. Stephanie tells the story.

Personally, I never believed in the effectiveness of eyelash serums. There’s a lot of brands out there claiming they work, but most don’t, and many use ingredients that can harm you. I’ve had too many friends tricked into buying serums just to find out it’s a waste of money and their lashes are worse off than when they started. 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 it worked within 4 weeks. I, of course, didn’t believe her. But then she showed me her before and afters and I was stunned. Week by week, I could see her eyelashes getting healthier and longer. Then I asked to see the ingredient list….

I was stunned to see all healthy, effective ingredients. Not a single ingredient caused alarm!

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 eyelashes before you sleep. It feels like placing water on your eyelid. Of course, I woke up the next day expecting a miracle… but alas, it takes longer than that to see results.

How Does It Work?

So while I waited, I looked into the science of Liaison. I wanted to know how it worked, and what it was aiming to do with my lashes…

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

Step 2: Our 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 throughout your day and while you sleep.

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

Did It Finally Work?

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

Since then, I’ve continued to apply and my lashes have only grown thicker and healthier. The amount of money I save on mascara from having to use less product is now used for Lash Bond.

I’ve been converted into a lash serum believer, and hope you will, too.

I loved how easy Liaison was to apply and use. It was just a simple few drops before bed and that’s it! My eyelashes have never looked better!

-Carrie, 24

I’ve spent so much time applying mascara and then removing it that it seemed to be destroying my lashes. Using Liaison is just the smarter, easier way for fuller lashes.

Debbie, 44

Nothing has ever worked this good for me! It’s unbelievable how this only took a few weeks to show results. Get Liaison if you can, it works!
