What Is Rodan and Fields Lash Boost?
- Enhance Lash & Brow Definition – Supports fuller-looking lashes and brows, adding depth and definition to your look.
- Hydrating Formula for Lash Strength – Helps maintain lash durability with moisture-rich ingredients, protecting...
Rodan and Fields Lash Boost is a nightly eyelash conditioning serum designed to enhance the appearance of lash length, volume, and darkness. The product comes in a small tube with an applicator brush similar to liquid eyeliner. This serum helps condition your natural lashes to appear fuller and longer when used consistently. The brand claims it can also work on eyebrows to make them look thicker and more defined.
The serum was developed by dermatologists Dr. Katie Rodan and Dr. Kathy Fields, the founders of Rodan and Fields skincare company. Their approach combines cosmetic ingredients with conditioning agents to nurture and strengthen lashes. Unlike temporary solutions like mascara or false lashes, Lash Boost aims to improve the actual appearance of your natural lashes over time.
One important note is that Lash Boost is sold as a cosmetic product rather than a drug. This means it is marketed to enhance the appearance of lashes rather than claiming to physically grow them, though many users report growth-like results.
The Science Behind Lash Serum
How does Rodan and Fields Lash Serum actually work? The product functions by conditioning and moisturizing your lashes to help them appear longer and fuller. Natural eyelashes grow through a cycle with three phases:
- Growth phase (anagen) – when the lash actively grows
- Transition phase (catagen) – when growth stops
- Resting phase (telogen) – when the lash eventually falls out
Most lash serums aim to extend the growth phase of this cycle. The key ingredients in Lash Boost work together to condition lashes, potentially helping them stay in the growth phase longer. This can result in the appearance of longer, fuller lashes over time.
The product contains a blend of peptides, biotin, and keratin that nourish the lashes. It also includes isopropyl cloprostenate, a synthetic prostaglandin analog that has been associated with lash enhancement effects. This ingredient has attracted attention for both its effectiveness and potential side effects, which we’ll discuss later in this review.
Key Ingredients in Rodan and Fields Lash Boost
Understanding what’s in your beauty products helps you make informed decisions. Rodan and Fields Lash Boost contains several key ingredients:
- Keratin and Hydrolyzed Keratin – proteins that strengthen hair and lashes
- Biotin – a B vitamin known to support healthy hair
- Sodium Hyaluronate – provides hydration and moisture
- Isopropyl Cloprostenate – a synthetic prostaglandin analog that may contribute to lash enhancement
- Panthenol – vitamin B5 that helps condition and moisturize
- Peptides – including Octapeptide-2 and Copper Tripeptide-1 that support healthy-looking lashes
- Allantoin – soothes and protects
- Pumpkin Seed Extract – contains nutrients that support healthy hair
The formula also includes Sweet Almond Seedcake Extract, which means people with nut allergies should consult a doctor before use. The combination of these ingredients creates a conditioning environment for lashes while potentially extending their growth cycle.
It’s worth noting that the inclusion of isopropyl cloprostenate has been controversial. This ingredient belongs to a class of compounds similar to those used in prescription glaucoma medications that were discovered to enhance eyelash appearance as a side effect.
Benefits of Using Lash Boost
People choose Rodan and Fields Lash Boost for several compelling benefits:
- Enhanced lash appearance – Users report longer, fuller, and darker-looking lashes
- Natural look – Results enhance your own lashes rather than adding artificial ones
- Convenience – Simple nightly application fits easily into existing routines
- Multi-purpose – Works on both lashes and eyebrows
- Cost-effective compared to lash extensions – Though the initial cost is high, it lasts longer than many salon treatments
- Clinically tested – Company claims 90% of study participants saw fuller-looking lashes
The serum helps maintain lash moisture and may enhance durability to protect against breakage. Many users appreciate that it allows them to wear less makeup, as their natural lashes look better without mascara.
Consistent users report they receive compliments on their lashes and enjoy the confidence boost that comes with enhanced eye features. The product has won beauty awards and developed a loyal following despite its premium price point.
How to Apply Rodan and Fields Lash Serum
Proper application of Lash Boost is essential for both effectiveness and safety. Follow these steps for best results:
- Remove all makeup and cleanse your face thoroughly
- Dry your eyelids and lashes completely – Moisture can prevent proper absorption
- Dip the brush once into the tube for each eye
- Wipe off excess product from the brush before applying
- Apply a thin line of serum only along the upper lash line (like eyeliner)
- Blot any excess serum from your eyelids or lashes
- Wait approximately 90 seconds for the serum to dry completely before going to sleep
- Avoid applying to the lower lash line as this may increase the risk of irritation
For best results, apply Lash Boost every night. Consistency is key for seeing improvement in your lashes. The company recommends using the product at night as part of your bedtime routine.
Important application tips include avoiding getting the product directly in your eyes, making sure your face is completely clean and dry before application, and ensuring the product is fully dry before closing your eyes or applying other products.
Real Results: Before and After
The ultimate question is: does Rodan and Fields Lash Boost actually work? According to clinical studies conducted by the company, the results are impressive:
- 90% of participants experienced fuller-looking lashes
- 85% saw longer-looking lashes
- 63% noticed darker-looking lashes
These results were based on an 8-week clinical and consumer study. The company showcases before and after photos on their website demonstrating dramatic improvements in lash appearance.
Real user experiences tend to align with these claims. Many users report noticeable improvements in their lash appearance after 4-8 weeks of consistent use. The lashes typically appear longer, fuller, and sometimes darker. Users with naturally short or sparse lashes often see the most dramatic results.
It’s important to note that individual results vary based on factors like age, genetics, and consistent application. Some users see dramatic improvements while others experience more subtle changes. Most people begin to notice results after about a month, with full results apparent after two to three months of regular use.
Potential Side Effects and Concerns
While many users experience positive results, Lash Boost has been associated with several potential side effects:
- Eye redness and itchiness
- Dry eyes
- Watering of the eyes
- Sensitivity
- Styes
- Inflammation of eyelid and eye
- Temporary darkening of skin around the eye area
- Lash loss
- Visible enhancement of hair around or outside the eye area
More concerning but less common reported reactions include iris discoloration, droopy eyelids, and exacerbation of meibomian gland dysfunction. These side effects are similar to those associated with prescription prostaglandin analogs used in glaucoma treatments.
The presence of these side effects led to several class action lawsuits against Rodan and Fields. In 2022, the company settled for $38 million regarding claims they failed to adequately disclose potential side effects related to the product’s prostaglandin analog ingredient. However, the company did not admit wrongdoing as part of the settlement.
The company now includes detailed warnings on their packaging and recommends discontinuing use if any adverse reactions occur.
Who Should Avoid Using Lash Boost?
Not everyone should use Rodan and Fields Lash Boost. The company specifically advises against use by:
- Pregnant or nursing women
- People undergoing treatment for glaucoma or cancer
- Individuals who have experienced conjunctivitis, dry eyes, eye infections, styes
- Those with irritation from other cosmetics applied in the eye area
- Anyone with eye-related disorders or illnesses
- People with nut allergies (due to almond extract in the formula)
If you have sensitive eyes or skin, consider doing a patch test before full application. Apply a small amount to a portion of your eyelid and wait 24 hours to check for reactions. If you experience any irritation, the product may not be suitable for you.
It’s always wise to consult with a healthcare provider before using lash enhancement products, especially if you have existing eye conditions or take medications that might interact with the ingredients.
Price and Value Comparison
Rodan and Fields Lash Boost costs approximately $153 for a 5ml tube. This is certainly a premium price point compared to drugstore lash serums. Is it worth the investment?
A single tube typically lasts 2-3 months with daily use, making the monthly cost about $50-75. When comparing this to alternatives:
- Drugstore lash serums: $10-40 per tube
- Other premium lash serums (like RevitaLash, Latisse): $100-150 per tube
- Eyelash extensions: $150-300 initial application, plus $50-100 for fills every 2-3 weeks
From this perspective, Lash Boost offers middle-ground value. It’s more expensive than drugstore options but potentially more effective based on user reviews. It’s also less expensive over time than maintaining eyelash extensions.
The company offers a 60-day money-back guarantee, which provides some protection for your investment. They also have a Preferred Customer program that provides a 10% discount, bringing the price down to about $135 per tube.

The experiences of real users provide valuable insights into Lash Boost’s performance. Positive reviews often mention:
- “My lashes are dramatically longer after just 6 weeks”
- “People ask if I’m wearing false lashes when I’m not”

Tips for Maximizing Results
To get the most from your Rodan and Fields Lash Boost, follow these expert tips:
- Be consistent – Apply every night without skipping days
- Use the right amount – More isn’t better and may increase irritation
- Ensure complete dryness before application – Moisture can dilute the product
- Be patient – Full results take 8-12 weeks to develop
- Protect your investment – Avoid rubbing eyes or using oil-based removers
- Apply with precision – Keep the product on the lash line, not in your eyes
- Consider reduced frequency if experiencing mild irritation – Every other day may work better for sensitive individuals
- Store properly – Keep at room temperature and tightly closed
Taking before photos can help you track your progress, as daily changes are subtle. Some users also report success with applying a conditioning lash primer during the day to further support lash health.
Remember that continuous use is necessary to maintain results. If you stop using the product, your lashes will gradually return to their natural state over a few months.
The Lawsuit Controversy
In 2022, Rodan and Fields settled several class action lawsuits for $38 million regarding Lash Boost. The lawsuits centered on claims that the company failed to adequately disclose potential side effects associated with isopropyl cloprostenate, a synthetic prostaglandin analog in the product.
The lawsuits alleged that this ingredient is similar to active ingredients in prescription drugs and should be regulated as a drug rather than a cosmetic. Plaintiffs claimed they experienced adverse reactions without proper warning.
As part of the settlement, Rodan and Fields agreed to revise their product labels to provide more detailed warnings and instructions. The company did not admit wrongdoing but provided compensation to affected consumers who purchased the product between October 2016 and March 2022.
This controversy highlights the importance of researching ingredients in cosmetic products, especially those used near sensitive areas like the eyes. The settlement has led to increased transparency regarding potential side effects.
Long-Term Usage Considerations
If you’re considering Lash Boost as a long-term beauty solution, several factors are worth considering:
- Ongoing cost – At roughly $50-75 per month, the annual investment is significant
- Maintenance requirements – Daily application becomes part of your routine indefinitely
- Potential tolerance – Some users report diminished results over time
- Lack of long-term studies – The company notes that Lash Boost has undergone 8-week clinical testing, but no long-term testing has been conducted
- Eye health monitoring – Regular check-ups with an eye doctor are advisable
Most users who continue with the product long-term find that results plateau after a few months. Discontinuing use will cause lashes to gradually return to their natural state within weeks or months.
Some dermatologists recommend occasional breaks from lash enhancement products to allow the natural lash cycle to reset, though the company does not specifically advise this.
Proper Storage and Shelf Life
To maintain the effectiveness of your Lash Boost serum:
- Store at room temperature away from direct sunlight
- Keep the tube tightly closed when not in use
- Avoid exposing the product to extreme heat or cold
- Don’t share your Lash Boost with others to prevent contamination
- Replace after 3 months from opening, even if product remains
The unopened shelf life is approximately 2 years. However, once opened, the company recommends replacing the product after 3 months for optimal safety and efficacy.
If you notice changes in color, consistency, or smell, discontinue use immediately as these could indicate contamination or product degradation.
Natural Alternatives to Consider
If you’re concerned about potential side effects or the cost of Lash Boost, several natural alternatives may help improve lash appearance:
- Castor oil – Contains ricinoleic acid that may support hair growth
- Coconut oil – Moisturizes and conditions lashes
- Green tea – Contains compounds that may support follicle health
- Vitamin E oil – Nourishing and protective
- Aloe vera gel – Soothing and moisturizing
These natural options tend to work more gradually and produce subtler results than commercial lash serums. However, they also generally have fewer side effects and are more affordable.
Many users combine approaches by using natural oils during breaks from commercial serums or applying them in the morning while using Lash Boost at night. This may help mitigate dryness sometimes associated with lash serums.
Final Verdict: Is It Worth It?
Rodan and Fields Lash Boost works for many users, producing visibly longer and fuller lashes with consistent use. The product delivers on its promises for most people who use it correctly and don’t experience adverse reactions.
However, the decision to use Lash Boost should consider:
- Your budget – The premium price may be prohibitive for some
- Your sensitivity – Those with sensitive eyes may experience irritation
- Your expectations – Results vary and develop gradually
- Your concerns about ingredients – Some may prefer more natural alternatives
- Your comfort with potential side effects – The risk of reactions must be weighed against desired results
For those seeking dramatic lash improvement without extensions or falsies, Lash Boost represents a viable option with proven results for many users. The 60-day money-back guarantee provides an opportunity to try the product with limited financial risk.
The final decision depends on your personal priorities, budget, and comfort level with the product’s ingredients and potential side effects.
