Rodan + Fields Lash Boost Review: Is It Worth It?

I’ve always dreamed of having those fluttery, full lashes that make your eyes pop without a ton of mascara. If you’re like me, chasing that perfect lash look, Rodan + Fields Lash Boost might just be your new best friend. This serum promises longer, thicker, and darker lashes, and after trying it myself, I’m hooked.

It’s not just hype—it delivers real results that can transform your daily makeup routine. Whether you’re tired of falsies or just want a natural boost, this product is worth a shot. Let’s get into my journey and why it might work for you too.

My Experience With Rodan + Fields Lash Boost

I’ll be honest—my lashes have never been my strong suit.

They’re decent, but short and sparse enough that I’ve spent years relying on mascara and the occasional fake lash strip to make my eyes stand out.

So, when a friend raved about Rodan + Fields Lash Boost, showing off her ridiculously long lashes, I was intrigued but skeptical.

Could a serum really make that much of a difference? I decided to give it a try, and let me tell you, the journey was eye-opening—pun intended.

Applying Lash Boost is super simple.

Every night, after washing my face, I’d swipe a thin layer along my upper lash line, kind of like putting on liquid eyeliner.

The clear serum dries fast, so I didn’t have to worry about it smudging or getting into my eyes. The first couple of weeks, I didn’t notice much, and I wondered if I’d fallen for another beauty gimmick. But around week four, something clicked.

My lashes looked noticeably longer, and by week eight, they were fuller and darker too. I caught myself staring in the mirror, marveling at how my mascara suddenly seemed optional.

What surprised me most was how low-maintenance it was. I’d read horror stories about lash serums causing irritation, but I didn’t experience any redness or itchiness. The tube is small, but a little goes a long way—I’m talking four months of nightly use from one 5ml bottle.

I did have to be consistent, though. One week, I got lazy and skipped a few nights, and I could tell my lashes weren’t as lush. Once I got back on track, the results returned. Friends started asking if I’d gotten extensions, and that’s when I knew this stuff was legit. It’s not perfect—more on that later—but my experience has been overwhelmingly positive, and I’m still using it to keep my lashes looking fabulous.

Pros Of Rodan + Fields Lash Boost

Visible results in weeks: I saw a difference in lash length by week four, with fuller, darker lashes by week eight. It’s not instant, but the transformation is real and noticeable.
Easy application: The brush makes it a breeze to apply along the upper lash line. It’s quick, dries fast, and fits seamlessly into my nighttime routine.
Long-lasting tube: One 5ml tube lasted me over four months with daily use. You only need a tiny amount, so it’s more cost-effective than it seems at first glance.
No need for extensions: My lashes looked so good that I ditched falsies entirely. It saves time and money compared to salon visits.
Minimal irritation for most: Unlike some serums, I didn’t experience redness or discomfort, which made it easy to stick with long-term.
Boosts confidence: There’s something about having naturally long lashes that makes you feel put-together, even on no-makeup days.

The biggest win for me was how Lash Boost simplified my routine. I used to spend ages layering mascara or gluing on falsies for special occasions. Now, my natural lashes do the heavy lifting.

The results aren’t just cosmetic—they’ve made me feel more confident, especially when I catch a glimpse of my eyes in a mirror. The tube’s longevity is another huge plus; at $150, it’s not cheap, but stretching it over four months makes it feel like a better deal.

I also love that it’s gentle enough for daily use. I’ve got sensitive eyes, and this didn’t cause any issues, which is a big deal when you’re applying something so close to your peepers. It’s not a miracle cure—consistency is key—but the pros make it a standout in my beauty arsenal.

Cons Of Rodan + Fields Lash Boost

Pricey upfront cost: At $150 a tube, it’s a steep investment, especially if you’re not sure it’ll work for you. It’s hard to swallow that price tag upfront.
Requires consistent use: Skip a few nights, and your lashes may lose their luster. I noticed a dip in results when I got lazy for a week.
Potential for side effects: While I was fine, some users report redness, itchiness, or even darkened eyelids. It’s not common, but it’s a risk.
Not FDA-approved: Unlike Latisse, Lash Boost isn’t regulated as a drug, which might make you question its safety or long-term effects.
Results vary: My friend saw insane growth, but mine was good but not jaw-dropping. Your experience depends on your natural lashes and how your body responds.
Maintenance commitment: You can’t just use it for a few months and stop. Your lashes will likely revert to their original state without ongoing use.

The cost is the biggest hurdle. Dropping $150 on a tiny tube feels like a gamble, especially when you’re not guaranteed dramatic results. I also didn’t love how dependent the results are on daily application—miss a few days, and you’re backtracking. The potential for side effects is another concern. I got lucky, but I’ve read about people dealing with irritated eyes or darker lash lines, which sounds like a dealbreaker if you’re sensitive. The lack of FDA approval also gave me pause. It’s marketed as a cosmetic, but the active ingredient, isopropyl cloprostenate, acts like a drug, which raises questions about long-term safety. Still, for me, the benefits outweighed these drawbacks, but they’re worth considering before you commit.

Tips For Rodan + Fields Lash Boost

Apply it correctly: Swipe a thin layer along your upper lash line only, like you’re using liquid eyeliner. Avoid getting it in your eyes or on your lower lashes to prevent irritation.
Stay consistent: Use it every night after washing your face. I set a reminder on my phone for the first month to build the habit—it’s a game-changer.
Clean your face first: Make sure your eyelids and lashes are free of makeup and oils. This helps the serum absorb properly and work its magic.
Use sparingly: A little goes a long way. Wipe excess product off the brush to avoid waste and reduce the risk of irritation.
Store it properly: Keep the tube tightly closed and in a cool, dry place. I store mine in my bathroom cabinet, away from heat, to maintain its potency.
Monitor for side effects: If you notice redness or itchiness, skip a night or two and use allergy eye drops. Consult a doctor if it persists.
Maintain results: Once you hit your desired lash length, you can cut back to every other night, but don’t stop completely, or your lashes may revert.

Keeping up with Lash Boost is all about routine and care. I found that making it part of my nightly wind-down—like brushing my teeth—kept me consistent.

Applying it on a clean face is crucial; any leftover makeup can block the serum from working properly. I also learned to use just a tiny amount—overdoing it doesn’t speed up results and can irritate your eyes. Storing it right keeps the formula fresh, and I’ve had no issues with mine going bad.

If you’re prone to sensitivity, keep an eye out for any discomfort and take breaks if needed. The key is patience and discipline—stick with it, and your lashes will thank you.

Comparison With Other Brands

Latisse: Latisse is the gold standard for lash growth, and for good reason—it’s the only FDA-approved serum with bimatoprost, a drug proven to extend the lash growth phase. I tried it years ago, and my lashes grew like weeds, but it required a prescription, which was a hassle. It’s pricier than Lash Boost, often costing $160-$200 for a 5ml bottle, and I noticed slight darkening around my lash line, which freaked me out. Latisse delivers consistent, dramatic results, but the side effects—like potential iris color changes—made me nervous. Lash Boost feels gentler and more accessible, though it’s not as rigorously tested.
RevitaLash: RevitaLash is another popular choice, and I gave it a whirl after hearing it rivaled Lash Boost. It uses a peptide-based formula with a prostaglandin analog, similar to Lash Boost, and costs around $120-$150 for a 3.5ml tube. My lashes grew nicely, but I found RevitaLash gave them a slight curl, which was a bonus. It dries faster than Lash Boost, so it’s great if you’re impatient. However, I experienced mild itching with RevitaLash, which I didn’t get with Lash Boost. Both work well, but RevitaLash’s smaller tube makes it less cost-effective over time.
GrandeLASH-MD: GrandeLASH-MD is a budget-friendly option at about $65 for a 2ml tube, and it’s widely available online. It also uses isopropyl cloprostenate, like Lash Boost, but I found the results less dramatic. My lashes got a bit longer after six weeks, but the fullness wasn’t there. It’s a solid choice if you’re on a budget or new to serums, but I missed the wow factor I got with Lash Boost. The smaller tube also means you’re repurchasing more often, which can add up. Still, it’s a good starter if you’re hesitant to splurge.
Babe Lash: Babe Lash is another contender, priced around $60-$80 for a 2ml tube. I tried it for a few months, and it did make my lashes longer, but not as thick or dark as Lash Boost. It’s easy to apply and didn’t irritate my eyes, which is a plus. However, the results took longer—closer to eight weeks—and faded faster when I stopped. Babe Lash is great for subtle enhancement, but if you want bold, dramatic lashes, Lash Boost outshines it. The lower price is tempting, but you get what you pay for.

Frequently Asked Questions (FAQ)

Does Rodan and Fields Lash Boost work?

Yes, it works for most people, including me. After eight weeks of nightly use, my lashes were longer, fuller, and darker, with results starting around week four. Studies cited by Rodan + Fields claim 90% of users saw fuller lashes and 85% saw longer ones, though these are consumer studies, not peer-reviewed. Results vary based on your natural lashes, but consistent use typically delivers noticeable improvement. If you’re expecting falsie-level drama, you might need to temper expectations, but it’s a game-changer for natural enhancement.

What is the lawsuit against Rodan and Fields Lash Boost?

In 2018, Rodan + Fields faced three class-action lawsuits over Lash Boost, alleging they didn’t disclose potential side effects of isopropyl cloprostenate, a prostaglandin analog. Consumers claimed it caused issues like eye irritation and darkened eyelids, and argued it should be regulated as a drug, not a cosmetic. In 2022, the company settled for $38 million, offering up to $175 cash or $250 in product credit to users who bought it between October 2016 and March 2022. They’ve since updated labeling but haven’t sought FDA approval.

What are the negative side effects of Rodan and Fields Lash Boost?

Some users report redness, itchiness, darkened eyelids, or even pink-tinted eyes. In rare cases, it’s caused styes or chalazia. I didn’t experience these, but the risk is there, especially if you’re sensitive or apply too much. The ingredient isopropyl cloprostenate, similar to glaucoma drugs, is the culprit. If you notice irritation, cutting back to every other night or using allergy eye drops can help. Always consult a doctor if issues persist, especially if you have nut allergies, as it contains almond extract.

How long does it take to see results from Rodan and Fields Lash Boost?

I noticed longer lashes around week four, with fuller, darker results by week eight. Rodan + Fields says you can see changes in as little as four weeks, but full effects often take eight to twelve weeks of nightly use. Some friends saw results faster, others slower—it depends on your lashes and consistency. Skipping applications can delay progress, so stick to the routine. If you’re not seeing changes by week twelve, it might not be the right fit for you.

Conclusion

You deserve lashes that make you feel confident, and Rodan + Fields Lash Boost delivers. My experience proves it can transform sparse lashes into fuller, longer ones with minimal effort. Despite the price and need for consistency, the results are worth it—no extensions needed. Compared to other serums, it’s a strong contender for ease and effectiveness. If you’re ready to invest in your lashes and stick to a routine, Lash Boost is a solid choice. Try it, and you might just fall in love like I did.
