Let me start with saying this: As I’ve mentioned in past CF articles, I’m obsessed with eyelashes – they’re really the first thing I noticed on people, and therefore, I’m obsessed with making mine as long and pretty as possible. Due to this obsession, I can’t leave a drugstore without buying a mascara (or five). So it’s only natural that I’d expand my experimentation into the world of eyelash treatments.


Over the past year or so, after the invention of prescription Latisse, cosmetics companies everywhere have jumped on the eyelash treatment bandwagon, creating products designed to give you the eyelashes of your dreams with just a few daily applications. My first foray into the eyelash treatment world was with L’Oreal’s Lash Boosting Serum ($20 on Walgreens), which I raved about here.

Cue the end of the summer, where I’m doing a late-night browse online — which never leads to good results where my bank account is concerned. I spot Rapidlash on sale for 30% off. (I think I bought it for around $30, although it currently retails for $50.)

You can guess what happened next – three minutes later, it was purchased and on its way to my house, and I finally fell asleep, dreaming of a mascara-less future. Wanna know how Rapidlash worked for me? Read on to see my review!

What is Rapidlash?

Rapidlash is an eyelash-enhancing serum. It comes in a mascara-like tube that has liquid liner-type brush at the end of it. After four-six weeks of daily application to the lashline, the product promises longer, darker, curlier lashes.

My Rapidlash Results:

Rapidlash day 1 - before picture

I started using Rapidlash right after using L’Oreal’s Lash-Boosting Serum – so the “Day 1” picture above is after three and a half months of using L’Oreal’s product.I was pretty diligent about applying Rapidlash every night on my lash line – I didn’t put any on my eyebrows, which is another way the product can be used.

Although I was a little worried about potential side effects, I did not experience any sort of discoloring, tingling or stinging when I used this. Sometimes, when it accidentally got in my eye, my eyes watered, but no more than they would have from eyeliner or mascara. The application is basically just like putting liquid eyeliner on – it’s simple and straightforward and only takes a minute.

Rapidlash results after a month of use

Because I’d been using a lash conditioner beforehand (which I stopped using in order to properly review this product), my lashes definitely felt sparser during the first few weeks of using Rapidlash.

To be honest, I didn’t see any results until six weeks in – the lashes that grew in then were definitely longer and it seemed like there were more of them along my lash line. However, the lashes that grew in were thin and brittle. After a full lash cycle, I definitely had a denser lash line with longer lashes, but I did not see a difference in lash darkness, lash thickness or lash curliness.

Rapidlash results after 6 months of use

After the full 13 weeks, I began using Rapidlash in conjunction with the L’Oreal Serum. The final picture above was taken after four months of daily Rapidlash application and probably six weeks of Lash Serum application – I’m not wearing any makeup in the picture,  yet my lashes look longer, darker and fuller than they used to with mascara!

Again, at this point I was also using L’Oreal’s Lash Boosting Serum on my eyelashes twice a day, so my results might not be typical of just Rapidlash usage. If I had to give my lashes a grade on their own, without any kind of serum, I’d give them a 30%.

After using just Rapidlash, I’d give them a 50%, but with Rapidlash and L’Oreal’s Lash Boosting Serum I’d give them a 75%.

Rapidlash – My Overall Review:

Rapidlash comparison

Bottom line? I saw a definite improvement in the quality of my lashes after months of using Rapidlash, but it’s not like anyone is going to come up to me and ask me if I have fake eyelashes on.

The pictures speak for themselves, but that said, I’m probably not going to repurchase Rapidlash again. Why? It’s expensive (it retails now for $50), and for the price, I want better results.

If you’ve never used any kind of eyelash serum and you want to try something, I’d recommend L’Oreal’s Lash Boosting Serum (I swear, they aren’t paying me to write that!) over this product, but I would not say RapidLash is a total waste – if you find it on sale or you’re given it as a gift, definitely give it a go! For now, I’m still looking for a serum that’ll give me Kim Kardashian lashes- hey, a girl can dream, right?

So, what do you guys think?

  1. I have very thin, brittle eyelashes and I always feel like I need to curl my lashes or apply mascara on it, usually I use a couple of coats of mascara, to get desired look.
    I have been using this product from last 2 years. I began to see a difference after around 1 week of use. I waited to write a review to make sure the change was real.
    The only one bad thing about revitalash product I have been noticed lately, is in the corner of my eye, where I first apply the serum, it gets a little red and puffy at times. When this happens I apply the other eye first, or I just take a break.
    Just go through this article for more information.http://www.thebeautyinsiders.com/revitalash.html

  2. I work in a drug store cosmetics department and have tried virtually every product we sell. To date, the best lash boosting mascara is Revlon Growluscious
    I saw really good results, with both length and thickness. It also doesn’t flake, gives fantastic volume and almost wears as good as waterproof, while being easy to remove.

  3. extra virgin coconut oil works wonders for lashes! I originally bought it for my dry & wavy hair, but after I read online how it might help thicken lashes, I thought, “Why not?” You can really see the difference within a week. My lashes got longer, thicker, & darker! Now to just find a good eyelash curler…

  4. Latisse sounds so scary! Your eyelashes might grow longer, but the huge list of possible side effect have me wondering why people think it’s worth it. I would definitely stick with store bought brands that aren’t as strong.

  5. Somehow that doesn’t sound like the safest product in the world. I mean, when it comes to eyes, I would stay away from chemicals.

  6. This is a great review! I’ve gotten individual eyelashes glued in recently and I’m not the type who wears make up often, however those lashes lasted for about 2 weeks, and they just transformed my face. I was getting compliments left and right, and i wasn’t even wearing makeup! Just the lashes. So I’ve recently become obsessed with my own lashes! Now i do my own individual lashes and glue them in, on the bottom thought, it gives it a more natural look.

  7. After hearing the side effects of Latisse, I’m really wary of the prescription eyelash treatments. I think I would stick to the drug store stuff that’s not at potent, especially since they seem to work and are cheaper.

    I was also considering getting eyelash extensions or dying my lashes, but I need to do more research on both procedures.

  8. Interesting, I didn’t know any of those products. But you’re lashes do look longer and fuller. I really like these reviews, find them very useful. Thanks

  9. Lilash worked for me, but it’s not cheap so I didn’t replace it when it ran out. Another problem with Lilash is it’s made with those medical eyedrops that have the weird pigmentation side effects (although I didn’t see any). I think I might try L’oreal’s..

    And your lashes do typically go back to normal after use with these products. My theory is that the serums extend the time before your lashes would typically fall out, making them both longer (as they continue to grow instead of shedding) and fuller (as new lashes start to grow while the old ones are still in place).

  10. Ashley- I’ve tried Rimmel’s Lash Accelerator and it works pretty well. I’ve noticed some growth, but it takes a while to see results. It’s pretty cheap so I’d give it a try, and if it doesn’t work, at least it’s a good mascara!

  11. Thanks for the review. I’m curious as to whether your lashes end up going back to normal after you stop using these products?

  12. I always like reading these reviews– good job Elizabeth!

    Have you tried Rimmel’s Lash Accelerator yet? I’m a big fan of Rimmel mascara and was wondering if that one was worth the hype.
