Let’s talk about R&F Lash Boost, the expensive eyelash serum you’ve probably seen online. I gave it a shot (because why not?) – and here’s my honest review of it.
Spoiler alert: it kinda works, but at what cost?
Quick heads-up: I paid for this on Amazon.com with my own money. No sponsorships. No filters. Just the raw truth from a mom of 3 who wanted longer lashes.
Let me just say this: Rodan + Fields Lash Boost is ridiculously expensive. I paid about $155 for one tube.

About R&F Lash Boost Serum
R&F (Rodan + Fields) Lash Boost is a nighttime lash-conditioning serum designed to improve the appearance of lash length, volume, and darkness. It’s applied once daily along the lash line (like eyeliner), and marketed as the magic solution for “naturally longer-looking lashes.”
It’s part of the Rodan + Fields skincare empire – you know, the same company behind those direct-selling reps and glow-up transformations.
What It Claims:
- Longer-looking lashes in 4–8 weeks
- Healthier, fuller lashes with continued use
- Easy nightly application
- Results without lash extensions
Ingredients in Rodan + Fields Lash Boost
This is where it gets interesting. The active ingredients include:
- Isopropyl Cloprostenate – a prostaglandin analog (yep, similar to what’s in some prescription lash growth products)
- Keratin – protein to strengthen lashes
- Panthenol – a form of Vitamin B5 for moisture
- Biotin – often hyped for hair growth
- Sodium Hyaluronate – helps with hydration
- Peptides – to support lash health
But that first one? Isopropyl Cloprostenate? That’s where the Rodan + Fields Lash Boost side effects come in…
My experience using R&F Lash Boost Serum
Week 1:
I was so excited, I practically ran to the mirror every morning to see if something magical had happened overnight. Of course, nothing had yet – but the serum felt easy to apply. No stinging. No redness.
Week 2:
Around day 10, I started noticing some redness and irritation near my lash line. It wasn’t horrible, but I looked a little tired even when I wasn’t. My eyes also felt a bit dry. At this point, I Googled: Rodan Fields Lash Boost side effects – and y’all, I wish I had done that before.
Some users reported permanent eye color change, irritation, and darkened eyelids (hyperpigmentation). Scary stuff.
Week 4:
By now, my lashes did look a bit longer. Not wildly fuller, but I could definitely see growth. Mascara went on smoother, and I didn’t need to curl my lashes as much. But my lids were looking slightly discolored. Not ideal.
Week 6:
Yes, my lashes looked the best they ever have. But I also had slightly darker skin near my upper lash line, which wasn’t cute. I started wearing concealer again (sigh) just to cover it up. My husband even asked if I was sleeping okay.
Does Rodan + Fields Lash Boost Work?
Yes – but at a cost. If your skin is sensitive, or if you’re concerned about side effects, this may not be worth the risk. It does make lashes look longer and a bit fuller, but the irritation, redness, and pigmentation made me stop using it after 8 weeks.
Is It FDA Approved?
No. R & F eye Lash Boost is not FDA-approved. That’s important, especially considering it contains a prostaglandin analog. Prescription serums like Latisse are FDA-approved and come with proper medical guidance.
Side Effects (That I Experienced)
- Red, irritated eyelids
- Dry eyes
- Slight hyperpigmentation
- Itchy lash line
- Darker upper lids over time
Some online reviews even mention iris color change, especially with long-term use – yikes.
Pros and Cons
✅ Pros:
- Lashes do grow longer
- Easy application
- One tube lasts 2–3 months
- Some users swear by it
❌ Cons:
- Expensive AF
- Side effects are very real
- No FDA approval
- Pigmentation and dryness
- MLM selling model (ugh)
- Cheaper, safer alternatives exist
Safer, Cheaper Lash Boost Alternatives on Amazon
If you’re looking for something similar without the nasty side effects, here are real Amazon alternatives I now recommend instead:
1. EssyNaturals Eyelash Serum
Much cheaper, still gives growth, and didn’t irritate my skin. (Top-rated!)
2. GrandeLASH-MD Lash Enhancing Serum
Closer to R+F in price but far better reputation and fewer reported side effects. Plus, it’s available without being stuck in a subscription.
3. RevitaLash Advanced Eyelash Conditioner
The OG. A bit pricey, but trusted by pros and doesn’t include the most controversial ingredients.
Final Verdict – Is Rodan + Fields Lash Boost Worth It?
Honestly? Not for me.
While I did get longer lashes, the side effects, cost, and overall risk made it a deal-breaker. There are too many great serums out there that don’t require a monthly subscription, don’t discolor your eyelids, and don’t leave your eyes feeling dry.
If you have sensitive skin, or if you’re hesitant about putting near-prescription ingredients near your eyes — skip this.
