Rodan and Fields Lash Boost Review: Side Effects, Benefits, Risks, and More

In 2016, Rodan + Fields (or simply R+F), the company behind the famous Proactiv brand, has launched a new product to compete with other eyelash enhancers available now on the market.
It’s called Lash Boost, which uses a blend of keratin, biotin, and peptides to boost your eyelash health and make them appear fuller, darker, and younger.

The question is: Is this product really worth the money?

Pros

  • It's easy to use. Simply apply to lash line each night with provided applicator.
  • It nourishes the follicles to promote new growth.
  • It may also be applied to eyebrows to get fuller brows.

Cons

  • It's pricey, $150 per tube, and it is unclear how long the tube will last with the recommended daily use.
  • It is also not known what happens if the product does not apply or rest on the lashes evenly. Could there be longer lashes intermingled with shorter lashes?
  • Lash Boost contains the ingredient isopropyl cloprostenate, a synthetic prostaglandin analog. The FDA noted that the use of the products which contain this ingredient should be supervised by a licensed practitioner, as isopropyl cloprostenate may lower intraocular pressure and other side effects such as ocular irritation, hyperemia, iris color change, macular edema, ocular inflammation and interference with glaucoma therapy.

Lash Boost Side Effects:

  • Irritation: Because the product is applied so closely to the eye, it is possible for the eye to become irritated especially if you accidentally get it into the eye. Rinsing the eye with water is the remedy for any Lash Boost product that inadvertently falls into the eye.
  • Tingling/Redness: A possible side effect is tingling or redness of the eye, at which point you are instructed to discontinue use if those symptoms persist. Mascara does not cause this type of side effect so it's curious as to what ingredients may cause these potential problems for users.
  • Darkening: Another potential problem is that Lash Boost can cause the lashes to darken. This may not be significant given that mascara does the same thing, but it does point to the issue of what ingredients can cause this.

Rodan + Fields recommends two options to find out if your skin will accept this product:

  1. Perform a patch test. Remove any makeup and make sure your face is clean and dry. Apply a small amount of Lash Boost serum on a small area of the lash line of your one eye. Allow it to dry before applying any other cosmetics near the area. Wait at least 24 hours and check for reactions.​
  2. Reduce the frequency of application. Sometimes, your skin needs to adjust slowly to a new product, and it may take a few applications for your skin to get used to it. If you experience a slight sensation for the first few days, try applying Lash Boost every other day (instead of daily) until the sensation no longer occurs. Then, gradually go back to daily application until your skin adjusts.

If your skin has not reacted to the serum, then you’re all set to continue using the product. But if tingling, itching, or redness persists, Rodan + Fields advises to discontinue the use of the product and seek for medical advice

What You Need to Know:

Key Features:

Lash Boost is an at home remedy that is more cost effective than extensions. The company recommends nighttime usage on a clean face and eye area. Application is as quick as a swipe over the lash line, similar to liquid eye liner.

Facts:

Application is only necessary on the top lashes because as you sleep, the product will also be absorbed by the lower lashes.

Concerns:

Longevity: Though it has been tested, it has not been on the market very long (about six months) so its long-term results and side effects of use are not widely known.

Limited Test Group

While Rodan and Fields touts excellent results of 90% of test participants experiencing fuller looking lashes after repeated use and 85% reporting longer looking lashes (I don't know the difference between fuller and longer looking that creates the 5% differential), it tells you in the fine print that the test group consists of only 41 participants.

Considering the price point and marketing splash the company is trying to make with this product, the test group is astoundingly small and subject to scrutiny.

Multi-Level Marketing

This is not a once and done product. You can't apply for four or even eight weeks and enjoy the benefits over a long period of time. Rodan and Fields is a multi-level marketing system so they expect recurring sales of the product and can offer you discounts and perks if you sign up to be a consultant (This is the best case scenario for the company because enrollment kits range in price from $395 to $995.) or as a preferred customer who gets perks of "up to and in some cases more than 10% discount off of retail price" if you sign up and pay a $20 initiation fee.

​Conclusion:

Rodan and Fields Lash Boost is a relatively unproven product that at $150 a tube is supposed to deliver incomparable lash building results negating the future use of mascara. The first red flag is that the test group only contained 41 women, hardly an adequate sample size to fully evaluate the performance of the product. Also, it has known side effects that are show stoppers for some users such as the use of almond oil as a carrier which can be a huge problem for peanut allergy sufferers..

YouTube videos have shown consultants posting results which aren't convenient since they are attempting to gain customers and sales dollars from the product. Here's an example:

It would be more compelling to see independent testing of the product compared to competing eye serums intended for the same purpose.

I have been using Lash Boost for 3 months. My lashes have grown a bit but not dramatically as I had hoped. i also have developed very red irritated eyelash line in the last week which is itchy. There is also darkness on my skin. Not worth the money

I came here to write a review for another product but remembered using this last year so I thought I would leave a review for this as well.

I bought the serum last year and in about 3 weeks I noticed that my lashes were longer and they weren’t falling out as much as before. So far so good. Fast-forward to two weeks later, I lost a good deal of my lashes. I decided to give it the benefit of a doubt and stopped using it for a month. Bought a new serum, started to continue using it, and my lashes started to fall out again.

Conclusion, the minimal growth isn’t worth losing your eyelashes over.

Been using it for 4 months.

Pros: does its job. Lashes are now longer and fuller. Very easy to apply and simple to use. Lashes have grown almost half a centimetre in the past few months.

Cons: For the past month or two, the Lash Boost solution would cause me to get a stye on my lid and this would occur almost every week – interchanging between the eyes. It does cause for skin darkening where the solution is placed – so a lot of the time I look like I have dark circles. Can cause eye irritation and itchiness. Expensive – you pretty much have to keep ordering a new bottle if you want to keep your lashes long and growing.

Overall: I would recommend this product if you have the money – it does what it’s meant to. I do like the product – you just have to use it with care.

    results are supposed to show up at 4 weeks, get better by 8 weeks and really WOW you at 12 weeks. Don’t give up…results get better and better. I had NO lashes at all after I stopped using extensions and now mine are touching my eyebrows!!

After using this I got an eye infection that wouldn’t go away that was later diagnosed as episcleritis. I don’t know if the serum was the cause but given the timing of the infection/episcleritis I am not using it again.

I have been using this product for about 2 months now. My lashes are much fuller and longer. I tried using nightly for the first month but had some irritation (A burning sensation, slight redness). The consultant told me to try using every other night so I have been doing this. I didn’t really see any benefit for the first 4 weeks at all, then almost immediately following that initial 4 weeks, it was a dramatic difference. My lashes are full and much longer. When I have mascara on, they hit my sunglasses which is annoying but not a problem worth complaining about. The price was a bit steep and like others have said, I have no idea how long this bottle will last but it is doing it’s job so I’m happy with the purchase.

I have been using this product inconsistently for about 6 weeks and I have seen quite a difference. I work in the beauty industry and have tried a lot of “miracle” products. I did notice at first I was getting some irritation in my eye the following morning and spoke to my consultant about it and she suggested I was using to much product and to wipe off the brush tip and using one dip for each and and that solved the issue. I would suggest it if you are looking for longer thicker lashes.

This, like all products, is not for everyone. Best of luck.

I used the lash boost for nearly 8 weeks, I saw some growth but not nearly as much as the before and after pictures that the consultants are posting. Once I stopped using the lash boost, my lashes fell out like crazy- I’ve got way less lashes than I had before starting this product.

I have used Lash boost about 5 days a week for about 5 weeks. My lashes are definitely a lot thicker and a bit longer and multiple people have said I look “really good” without knowing about it. HOWEVER!!!! My eyelids are super red when I use the product especially if any face cream etc is intermingled by accident. And, and this is bad, I have started have dark long hairs sprout on lower corners of my eye area/upper check. I think at night some it running down onto my skin. I sleep on my side and of course eyes water etc. I also noticed that I have a lot of hair below my brow that is new. Although I have been using very little product and following directions perfectly I am going to discontinue use before I turn into a red eye hairy eyed monster. Whaaaaa! I so wanted this to work.

Please look at the ingredient list. Lash Boost contains the ingredient Isopropyl Cloprostenate. From what I have read, Rodan and Fields Lash Boost should only be used under the supervision of your doctor. http://www.cosmeticsandtoiletries.com/regulatory/claims/120476614.html

Awful. My upper eyelids became severely irritated, dry and my lashes fell out. I have a patch of missing eye lashes on both eyes. Dissatisfied and dissapointed does not even begin to explain my thoughts on this product. Never again.

I actually LOVED this product except now I’m having issues. Around week 3 I noticed my lashes were growing really fast, however I’m on week #5 and I’ve developed a massive Stye on my left lid and it’s super painful. The lid is extremely swollen so I have to stop using this product =( I can say it’s because of this product as I haven’t worn any eye mascara or used anything else on my eyes in 2 weeks and it’s swollen painful starting in upper lash area. Maybe i’m just unlucky.

    I too developed styles. Week two, bottom and week five top. Ouch!

Like other lash serums Lash Boost is meant to condition your lashes so they will be stronger, therefore lasting longer in the normal lash growth cycle. If you stop using, your lashes will return to normal because you are no longer giving them that nourishment. Also, the tube will last around 3 months and then should be replaced because it loses its efficacy. Lash Boost was developed over 5 years before being put on the market. With all that being said, everyone reacts differently to any product. If any irritation or bothersome side effects are presented, stop use and return it for a refund (within 60 days). Yes, I am a consultant.

Been using this product for 3 months with minimal results. My lashes are a little longer, but not thicker at all. I got much better results with Latisse & much less irritation. I was told by my consultant that my eyes had to get used to the serum, to make sure I didn’t get any of the product in my eyes (duh!) & to wipe off any excess. My eyes still get red & puffy & feel like I have sand in them. Definitely won’t be reordering!

So I just stumbled on this article and had to comment. I have been using lash boost for 4 weeks and my eyelashes do look a little longer. However, last week I got a stye, which I haven’t had in a long time and now I am currently on antibiotics, steroids, and drops because I have double kerititis in both eyes. I woke up in the morning two days ago and my eyes were so painful and blurry and luckily my eye doctor squeezed me in. This is horrible.

Ps. I have used latisse in the past and NEVER had a reaction like this. I’d rather have short, stubby
Lashes then lose my eyesight, which keratitis is one of the number one causes of.

I LOVE Lash Boost! I didn’t really think it would work, but I tried it anyway. After about 6 weeks I started seeing results, and after 8 weeks my lashes got HUGE! They look fantastic! I have red hair so they still aren’t very dark, but with mascara they are much more dramatic than before. I ran out and forgot to reorder, but amazingly they still look long! Love this product 🙂

My lashes did not grow longer. I started to notice hair growth under my eyes and the tops of my cheeks. I stopped using this product immediately. Will the hair growth go away? I’m freaking out.

I have only used this for about 4 days, but every morning I wake up with muck in the corners of my eyes and it continues throughout the day. After reading these reviews, I am concerned about continuing the use.
