I’ve always been jealous of people with naturally long, fluttery lashes. Mine have always been short and a bit sparse, so when I saw all the before-and-after photos of Rodan + Fields Lash Boost, I was hooked. The brand promised longer, darker, fuller lashes in just weeks, and some of the results online looked almost too good to be true. The catch? It’s expensive, around $150 for a single tube, but I convinced myself it was worth the gamble.
What is Rodan + Fields Lash Boost?
Rodan + Fields Lash Boost is a lash growth serum designed to enhance the length, volume, and darkness of your lashes. You apply it once a day along your upper lash line, much like liquid eyeliner. The active ingredient is isopropyl cloprostenate, a prostaglandin analog, a compound similar to the medication used in glaucoma eye drops that’s been shown to stimulate lash growth.
Why I Tried It
I’ve tried mascara, false lashes, and even lash extensions, but they all have drawbacks… flaking, falling off, or damaging my natural lashes. A serum that could grow my own lashes sounded like the perfect solution. Plus, the promise of “noticeable results in 4 weeks” had me picturing my future self batting movie-star lashes by summer.
My Experience Using It
When I first started using Lash Boost, I was religious about it… one swipe along my upper lash line every night before bed. By the end of the first month, I thought maybe I was imagining things, but at around week six, I caught myself in the mirror and noticed my lashes looked darker and a bit longer. Friends started asking if I’d gotten extensions, which felt like a win.
But there was a trade-off I didn’t see coming. Around the same time, I started waking up with slightly red, irritated eyes, and my lids sometimes felt tight or itchy. It wasn’t unbearable, so I pushed through, especially since the lash growth was so satisfying to see.
By month three, my lashes were the longest they’d ever been, but the irritation became harder to ignore. Some mornings, my eyes looked bloodshot enough that I reached for sunglasses before coffee. Then, about two weeks after I stopped using it, I noticed a few lashes falling out at once. Over the next month, my lash line looked thinner than before I’d ever started Lash Boost.
It was frustrating… like I’d traded temporary “wow” lashes for a permanent cycle of chasing results. I’ve since learned that’s a pretty common experience for people who stop using prostaglandin-based serums: your lashes revert, and sometimes they overcorrect, leaving you worse off than when you began.
Pros
- Noticeable lash length and volume after 6–8 weeks
- Easy, once-a-night application
- One tube can last several months if used sparingly
Cons
- Expensive ($150+ per tube)
- Can cause eye redness, irritation, or discoloration of the eyelids
- Results fade and lashes may shed after stopping
- Contains a prostaglandin analog, which can have long-term side effects
Is It a Scam?
No, Rodan + Fields Lash Boost does work for many people, including me. The lash growth was real. But the side effects, cost, and temporary nature of the results make it feel like a bait-and-switch. If you’re not ready to commit long-term (and budget for refills), the initial wow factor can quickly turn into disappointment.
Where to Buy and Price Point
Rodan + Fields Lash Boost is sold through the brand’s website, through independent consultants, and occasionally on third-party sites like Amazon (though counterfeit risk is high there). The retail price is typically around $150+ for a 5mL tube.

Conclusion: Would I Recommend It?
If you’re willing to risk irritation and commit to using it indefinitely, Lash Boost can give you noticeably longer and fuller lashes. But if you’re looking for a low-maintenance or permanent solution, this isn’t it. For me, the side effects and post-use shedding outweighed the benefits. I’d rather stick with a good mascara or try a gentler serum than keep up with the Lash Boost cycle.
