It’s 2020 and the hunt for the best eyelash growth serum is in full bloom. And why wouldn’t it be? It’s no surprise that lashes are big business.

In a world where there’s nothing more coveted than a set of full and long lashes – other than, maybe, a set of equally full brows – there are hundreds of beauty brands vying for your attention.

With growth serums galore, each of which promising to take lackluster lashes to va va voom , how do you go about choosing the best one?

The Secret to Choosing the Best Lash Growth Serum.

Every day, a new lash serum pops up to promise the best eyelash growth of your life. The problem is that the vast majority of lash growth products don’t live up to their claims.

So how do you separate the wheat from the chaff and find the perfect lash growth serum for you? There’s one word you need to know.

P is for Prostaglandin.

The easiest way to know which eyelash growth serums will actually result in dramatically longer, thicker lashes? Well, you have to look and see if the lash growth serum contains prostaglandin ingredients. These ingredients usually show up as either Isopropyl Cloprostenate or Prostaglandin I.C. on the ingredients list.

Sometimes, though, they’re a lot less obvious, showing up as lesser-known names like Dechloro Dihydroxy Difluoro Ethylcloprostenolamide and Methylamido Dihydro Noralfaprostal (MDN).

Up until a few years, many eyelash growth products used to contain these active ingredients, which is why so many lash serums were impressively effective.

But recently, the FDA — most likely egged on by Allergan (the makers of Latisse) — warned various eyelash growth companies to remove these ingredients. This is why so many eyelash growth serums that used to provide dramatic lash growth — like Peter Thomas Roth’s Lashes to Die for and RapidLash — have been reformulated into much less effective versions.

Because of this change, most of the well-known lash growth serum brands are no more than nourishing eyelash conditioners now. That isn’t to say that eyelash conditioners do not work — a few are surprisingly effective — but they do not guarantee drastically longer, thicker eyelash growth. In other words, they don’t produce this sort of dramatic before-and-after result:

If your goal is slightly longer lashes and a fuller, darker lash line — the best eyelash conditioners will do the job. But if you’re looking for va-va-voom lashes — you know, the sort of eye fringe that needs no liners or mascaras to make your eyes pop — you’ll need a prostaglandin ingredient to get you there.

But Prostagladins Aren’t for Everyone.

Seriously long and thick lashes sounds like a dream come true but there is a downside — prostaglandin-containing lash growth serums aren’t perfect.

As you might already know, prostaglandin ingredients come with drawbacks of their own, including some potential side effects that you should know about, like:

Itchiness in the eyes, dryness and/or eye redness. Eyelid skin darkening and redness of the eyelids. This eyelid skin change is a result of increased melanin in the skin but it is not permanent and will go away several weeks after you stop using prostaglandin. The most serious, and permanent, side effect is that prostaglandin analogues can cause irises (the colored part of the eyes) to darken. This means that light-eyed users can experience a darker (browner) eye color change.

The last side effect is something everyone should know before trying a prostaglandin-based eyelash growth serum. That’s because this particular side effect is permanent and will not change back even if you stop using the product.

This is why we do not recommend prostaglandin-containing lash serums for light-eyed people. Of course, the side effect doesn’t affect everyone with light-colored eyes but why risk it?

If you’ve got brown eyes, you’re good to go but if not, choose a good eyelash conditioner instead. A good eyelash conditioner with high quality ingredients will still give you beautiful results without the risk to the color of your eyes. Our favorite, Cos Naturals’ Peptide Lash gives remarkable results with all natural ingredients.

But overall, despite the potential side effects, it does need to be said that if you’re looking for dramatic lash growth, prostaglandin-containing eyelash growth serums are the only ones that can provide that kind of impressive eyelash growth. It’s up to you to weigh the pros and cons and decide whether to choose an eyelash conditioner or one of the eyelash growth serums below.
