Prostaglandin-Free Lash Serums: What Lash Artists & Clients Should Know
If you’ve spent any time looking for an eyelash serum, you’ve probably noticed there are a lot of options out there—and not all lash serums are formulated the same way.
One ingredient category that has received more attention in recent years is prostaglandins and prostaglandin analogs. While these ingredients can be effective at enhancing the appearance of lashes, they can also come with potential unwanted side effects around the eye.
That’s one of the reasons we chose a different approach for our Honeybee Lash Co. Eyelash Enhancing Serum: a peptide-based, prostaglandin-free formula that can also be used with lash extensions.
So, what exactly does that mean? Let’s break it down.
What Are Prostaglandins in Lash Serums?
Prostaglandins are naturally occurring compounds in the body. Certain prostaglandin analogs were originally developed for medical uses, including treating glaucoma. One unexpected effect was noticeably longer and fuller eyelashes.
This eventually led to prostaglandin analogs being used for eyelash enhancement. You may recognize bimatoprost, the active ingredient in prescription Latisse.
Some cosmetic lash serums use other prostaglandin-like ingredients to produce a similar lash-enhancing effect.
Why Are Some People Avoiding Prostaglandin Lash Serums?
While prostaglandin-based formulas can produce noticeable results, they aren’t necessarily the right choice for everyone.
Prostaglandin analogs used around the eye have been associated with potential side effects including:
- Redness and irritation
- Darkening of the eyelid skin
- Changes in pigmentation
- Dry or itchy eyes
- Loss of fat around the eye, which may create a more hollow or sunken appearance
The last one has become an especially common concern when people are researching lash serums.
This doesn’t mean everyone who uses a prostaglandin-containing product will experience these effects. However, it’s one reason some consumers specifically seek out prostaglandin-free lash serums.
What Is a Peptide Lash Serum?
Peptides are short chains of amino acids—the building blocks of proteins.
Rather than relying on prostaglandin analogs, peptide-based lash serums are designed to condition and support the natural lashes, helping them look healthier, stronger, fuller and longer over time.
Our Eyelash Enhancing Serum contains a blend of peptides including:
Myristoyl Pentapeptide-4
Acetyl Tetrapeptide-3
Palmitoyl Tripeptide-1
The formula is prostaglandin-free and does not contain prostaglandin analogs.
For us, this was an important distinction when choosing a serum we felt comfortable offering to both lash artists and their clients.
Can You Use Lash Serum With Lash Extensions?
Yes—but choosing the right formula matters.
Our Eyelash Enhancing Serum is specifically formulated to be compatible with eyelash extensions, so you don’t have to choose between wearing extensions and taking care of your natural lashes.
As a lash artist, I actually love the idea of supporting the natural lashes underneath the extensions. After all, healthy natural lashes give us the best foundation to work with.
There is one thing extension wearers should know, though. When using a lash-enhancing serum, you may notice your natural lashes growing out more quickly. Since the extension is attached to the natural lash, this can mean your extensions appear grown out sooner and you may need fills a little more frequently.
That’s not necessarily a bad thing—it simply comes with supporting your natural lash growth cycle.
Who Is a Peptide Lash Serum Good For?
A prostaglandin-free peptide lash serum can be a great option for someone who wants to improve the appearance of their natural lashes without using a prostaglandin-based formula.
It may be especially appealing if you:
- Wear eyelash extensions
- Want fuller or longer-looking natural lashes
- Have removed extensions and want to focus on your natural lashes
- Want to condition and support your lashes
- Specifically want to avoid prostaglandins or prostaglandin analogs
- Prefer a peptide-based daily lash serum
Consistency is key with any lash-care routine. Natural lashes grow in cycles, so don’t expect an overnight transformation.
How to Use Our Eyelash Enhancing Serum
Using it is simple. Apply a thin layer along the lash line once daily using the applicator. Allow the serum to dry completely before applying other eye products.
More isn’t necessarily better. A small amount applied consistently is all you need.
Prostaglandin-Free vs. Prostaglandin Lash Serum: What’s the Difference?
The biggest difference comes down to how the formulas are designed to enhance the lashes.
Prostaglandin-based products use prostaglandin or prostaglandin-like compounds that can significantly affect the lash growth cycle. Peptide-based formulas take a different approach by using ingredients intended to condition and support healthier-looking natural lashes.
Neither category should be treated as interchangeable, which is why I think it’s important to actually read the ingredient list instead of relying solely on the words “lash serum” on the package.
If avoiding prostaglandins is important to you, look specifically for a product that states it is prostaglandin-free.
A Lash Serum Made With Lash Artists in Mind
After years of working as a lash artist, one thing I will always preach is that the health of the natural lash matters. Extensions should enhance what you already have—not come at the expense of your natural lashes.
Our Honeybee Lash Co. Eyelash Enhancing Serum is a peptide-based, prostaglandin-free option designed to support longer, thicker and healthier-looking natural lashes while remaining compatible with eyelash extensions. Whether you wear extensions or simply want to give your natural lashes some extra love, it’s an easy addition to your daily lash routine.
