Revitalash Vs fLash: The Ultimate Eyelash Serum Review

20 Comments

We’ve all done the mascara, false lashes and extensions thing – but none of them are natural-looking, nor are they permanent… sigh.

So what’s the next best thing? Eyelash serums!

It’s no secret that eyelash serums have become an absolute lust-have commodity in the beauty world, but they are just so goddamn expensive.

I put two of the most popular eyelash serums, RevitaLash and fLash, to the test to determine which one (if any) came out on top when it came to growth, skin sensitivity, ingredients and price.

Interested? Read on to see my reviews and see my results.

I used both RevitaLash and fLash over a three month period (one serum for each eyelid), and I can confidently say that they both worked to help my lashes grow longer.

Though in saying that, each one has it’s own pros and cons…

Pros & Cons: RevitaLash

I’ve been using RevitaLash for about a year and a half now, and I’ve never looked back.

It was the first lash serum I’d ever used, and I never really thought twice about looking around for other options until I was sent a sample from fLash… and I thought to myself, why not do a comparison review?

Growth?

I still remember my very first time using it… I woke up the next day and swear I could see new growth! My lashes continued to steadily grow over the three month period, and I got a number of compliments on them.

Skin sensitivity?

My eyes did suffer from a bit of skin sensitivity at first (which I read was normal), I experienced a bit of redness around the tip of my eyelid for the first couple of weeks, but then it stopped.

I also experienced a very slight dryness to my eyes in the mornings after I’d used it, but it didn’t really bother me and I couldn’t really tell if it was from the serum or not.

Ingredients:

RevitaLash uses unique bio-peptin patented to Athena cosmetics, which is a combo of Biotin and panthenols along with wheat germ, saw palmetto and other vitamins, making it a top range skincare for your lashes!

Plus they also donate a percentage back to breast cancer research (see the story behind RevitaLash here, it’s so sad so be sure to have the tissues at the ready).

RevitaLash is vegan friendly contains no paraben no chemicals and is cruelty free.

Price?

The price varies, depending which outlet you go through – but from what I can see online, these serums vary from $119 – $125.

You can buy RevitaLash in NZ from The Beauty Lounge.

Pros & Cons: fLash

I first came across fLash in a review on my friend Angie’s blog Gurl Interrupted and I almost DIED after seeing the results she had with this baby.

Growth:

fLash took me a little longer to see the results, I found it wasn’t as fast-working as RevitaLash (but that’s just me – I have a girlfriend who saw results within a week).

Though as you can see in my comparison photos down below (scroll down), there was basically no difference in growth after the three month period.

Skin Sensitivity:

Like RevitaLash, I experienced slight redness on my eyelids in the mornings after using it the night before. There wasn’t any irritation or puffiness.

Ingredients:

fLash includes: water, hydroxyethylcellulose, glyc-erin, panthenol, hydrolyzed soy protein, bButylene glycol, carbomer, polysorbate20, palmitoy1, oligopeptide, tetrapeptide-­7, sodium hyaluronate, soluble collagen, iso-propanol phenylhydroxypentene dihydroxy–cyclopentylheptenate, hydrolyzed wheat protein, pg propyl silanetriol, disodium EDTA, phenoxyethanol and ethylhexylgycerin.

Like RevitaLash, flash has never been tested on animals.

Price:

At $69 this has got to be one of the most cost-effective eyelash serums on the market. I’ve yet to find one that’s cheaper than this!

You can buy fLash in NZ from The Beauty Lounge.

You can see in the images below that there isn’t really too much difference in growth between the two serums (right: RevitaLash left: fLash).

I could only really see the results after putting mascara on, as my lashes are really fine and almost blonde on the tips which makes it really difficult to see their length.

I’m wearing Benefit Cosmetic’s Roller Lash mascara in case you’re wondering – it’s legit the best mascara in the world.

The only other difference between the two, would be the brush size and amount of serum that came with each application.

As you can see in the above image, fLash has quite a large amount of serum compared to RevitaLash – I’m not sure why or if this makes a difference in any way.

It made me feel like fLash would make my eyelashes grow more because of the amount of serum I was applying, but as you’ve seen the length of my lashes were pretty much the same.

revitalash_2

Each serum brand claims to last you about 3 months, but I found they still had a quite a bit of product left after the 3 month period, so I’d say they’d last around 4-5 months.

So which is better – RevitaLash or fLash?

Well to be honest, there wasn’t all that much difference about them besides their price, a tiny amount skin sensitivity and the amount of product that came off the brush.

The only downsides to them both would be that you need mascara to really see the results, AND also it can be a real pain to remember to put it on every night (I’m lazy and forget).

What’s your favourite eyelash serum and why? Have you tried RevitaLash or Flash before? What were your results?
