Most effective eyelash serums are top-rated. But sometimes, you’ll find a gem that isn’t as widely raved about online. That could be the case for Nulastin—a brand we’ve never heard of before. But based on what it promises, it might be worth considering.
Nulastin was developed by Dr. Burt Ensley, a Ph.D. in microbiology. He was also the former director of Amgen’s Specialty Chemicals Group. If anyone knows what they’re doing in growing hair and lashes, it’s him.
Dr. Ensley is the creator of the Keracyte® Elastin Complex. This complex has become quite the popular ingredient in restorative hair care. Nulastin uses this same complex to help people grow their hair back, one serum at a time.
Nulastin and its hair-growing products have been featured in publications and news channels. These include Allure, CBS, USA Today, Vogue, and more.
Today, we’ll delve into their lash serum. This serum is clinically proven to boost lash density and length. Thanks to the elastin therapy it provides—but more on that later.
But how long will this serum take to work? Let’s look at what the serum’s formula contains to see whether it can give its promised results.
Nulastin Eyelash Serum Review

The LASH Follicle Fortifying Serum with Elastaplex® elongates and thickens thin, short lashes. Thanks to its formula, it makes sparse strands look full and luxurious. A 12-week study showed that this serum increases lash length by up to 60%.
It’s made with a combination of naturally-derived and science-driven ingredients. Five patents back it, so you know the formula is innovative and the first of its kind.
These ingredients include proteins, antioxidants, peptides, and more. Together, they boost elastin production in your body, leading to stronger, longer lashes.
This American-made serum is easy to use. Apply above your clean, dry lash line twice a day—every morning and evening. You can bring it down to once a day when you get the results you want. Each tube can last 4-6 weeks at a time.
You get a lifetime customer satisfaction guarantee. If you don’t like your results, you can get your money back.
Nulastin Eyelash Serum Ingredients
Nulastin Lash Serum is formulated with many science-backed complexes and proteins.
First, there’s SymPeptide® XLash by Symrise. This synthetic lipo-oligopeptide helps thicken your lash density. It enhances the fullness of your lashes.
Then, there is Elastatropin®, a substance synthesized by Dr. Ensley himself. It helps your body produce more elastin, the protein that makes your hair and skin firm and elastic.
The serum doesn’t contain any fragrance. This is terrific for those who are allergic to synthetic fragrances. It means your eyes are less likely to be irritated with the serum.
However, we’ve noticed that it contains many ingredients that don’t help with lash growth. For example, while SymPeptide® is for hair growth, EPA lipids will merely moisturize your lashes, not grow them.
What to expect from Nulastin Eyelash Serum

Nulastin promises that your lashes can look thick and luxurious in just a few weeks. And in a month, you’ll see a noticeable change in length and fullness.
But this sounds like a bit of an overpromise. We’d much more believe their clinical study, which shows that it takes 12 weeks to see an improvement in lash length.
For some people, the Nulastin lash serum works excellent. Even the Nulastin CEO says that she gets unsolicited compliments on her skin thanks to Nulastin’s science-backed formulas.
But not everyone is as lucky. Each person responds differently to various lash serums. The only way to find out if a lash serum will work for your hair type and genetics is to try it firsthand.

Nulastin Eyelash Serum Reviews
Nulastin has a good score on SiteJabber, rounding up at 4.19. But when you look at the reviews for the lash serum, there are negative comments among the good reviews.
Some women shared that they experienced eye redness, dryness, and allergic reactions.

While there aren’t YouTube reviews on the serum, there’s one posted by Nulastin itself. In the video, the user talks about how their skin was sensitive after a day or two of using the serum.
Based on these reviews, we highly discourage those with sensitive eyes from using the product. The same goes for those with known allergies to the ingredients.
Nulastin Eyelash Serum Side Effects
Nulastin says that the serum should not cause any sensitivity or irritation on their brand website. Still, they remind people to patch test before using it all over the lash line.
Although the brand believes the serum shouldn’t cause discomfort, be wary of side effects.
These include:
- redness,
- dryness,
- itchiness,
- pigmentation in the lid, and more.
If you experience any of these, stop using the product and get checked by a doctor.
Conclusion
The Nulastin LASH Follicle Fortifying Serum with Elastaplex® has many pros. It’s made with good, science-driven ingredients. Its complexes and overall formula are patented, so you know it’s a pioneer in the lash-growing world.
However, this serum is quite expensive. There’s also a high chance of seeing allergic reactions.
If you don’t have sensitive eyes or mind having to buy 3-4 tubes to see results, it’s worth a try.
Hopefully, in 12 weeks, you’ll see longer, fuller lashes, just like the brand promises.
