I’ve now been using this lash oil for almost a year and my lashes are stronger and longer! Truly a life saver for my lashes after always having classic lashes done.
My lashes were so short and damaged after years of lash extensions. This lash oil completely changed them! You can see in the photos the amazing amount of growth.

Nothing unnecessary
Apply a small amount to clean, dry lashes and brows using the applicator. Sweep from root to tip, focusing on areas that need extra care. Use nightly and allow the formula to dry fully. With regular use, lashes and brows appear stronger, fuller, and more nourished in as little as four weeks.
With consistent nightly use, lashes and brows appear stronger, fuller, and healthier within four to six weeks. Because this formula works with your natural growth cycle, results build gradually rather than forcing rapid growth.
Most lash serums rely on synthetic growth compounds (prostaglandins) to artificially stimulate growth. These can cause irritation, redness, or unwanted side effects.
Our Lash & Brow Oil is a concentrated, waterless blend of plant seed oils that nourishes the follicle and supports natural growth over time. No prostaglandins, hormones or fillers. Just pure, plant powered strength.
Yes. The formula is designed to be gentle enough for nightly use, even around sensitive eyes. It contains no prostaglandins, alcohol, or known irritants. We always recommend a patch test before first use.
Yes. The formula is designed for both lashes and brows. Apply a small amount from root to tip, focusing on sparse or fragile areas.
No. This formula contains no prostaglandins or synthetic growth agents, which are typically responsible for those side effects in some serums.
With nightly use, one bottle typically lasts six months or more. A little goes a long way because the formula is concentrated and waterless.
We do not recommend using it with lash extensions, as oil based formulas can weaken the adhesive and reduce retention.
It is, however, ideal for lash lifts. After a lifting treatment, lashes can feel dry or fragile, and this nourishing oil helps condition and restore them, keeping them soft, healthy, and glossy.
For best results, apply once daily at night to clean, dry lashes and brows. Consistency is key.
Water is often used as a filler in cosmetics. By removing water, this formula remains highly concentrated and potent, meaning every drop delivers active nourishment rather than dilution.
Yes. The Lash & Brow Oil is vegan and cruelty free.
Absoloutely amazing Lash and Brow Oil . with visible results
Never have I had lashes this good.
I’ve used many lash oils and ones with a far heftier price tag and have never achieved results like this. I chose Isobel Perl for its natural ingredients after receiving a cancer diagnosis and having chemotherapy for three months - i lost a significant amount of lashes and those I didn’t lose broke. I wanted results but I wanted natural ingredients. Here I am today with the best lashes I’ve ever had after consistent use since the beginning of July. Highly recommended amazing product that I am telling everyone about at every opportunity.
Been using the brow and lash oil for six months and wow I absolutely love it. Iv used a very well known brand but haven’t had lasting results like this.
Wow! What is this witchcraft?! I so wish I took before and after pictures, as the results are incredible. After having a Korean LVL for the first time I noticed my eyelashes falling out dramatically. I then started using this and it is pure magic! Thank you thank you thank you! Will 1000000000% be purchasing again and already recommended to friends and colleagues.
Absolutely stunning and well made product! My lashes were straight, and not very long, after using the lash and brow oil became fuller and longer! I will post a pic of before and after!
I have eczema and it can often travel to my eyes if I’m not careful with my products. This product is so gentle on my eye area and my lashes feel so soft. I just started using it, and I’m so exchited to see the progress 💕
I have very sensitive eyes. This product is perfect for my lashes. The bonus is I can use it for my brows too!
10/10!!! By far the best brow oil I’ve ever used, the difference in my brows after only a month and a half is incredible. Can’t recommend enough!! 👏🏼
Beautiful packaging and bottle but the brush is quite big and not dense enough, I rub my finger across it and apply it to my brows only….I’m sure my lashes look healthier too? Happy to say that I have some regrowth where I needed it on my brows . I’ve used it for a few weeks now and I think it’s going to last me 5/6 months :-)
The product is amazing and made my lashes alot longer, but the packaging keeps leaking. I have to keep it on my vanity standing upright and it still leaks. Also the packaging is made of glas so it breaks instantly if you drop it. I bought my first lash serum in december and dropped it in march so alot of the product got wasted and i had to buy a new one. Also it would be nice to be able to buy the eyeliner applicator again instead of the spoolie, like before when you could choose which one you wanted.
I started using Perl lash oil after I had some nasty side effects from well known brands. Love that the formula is natural & noticed a big improvement in the thickness & length of my lashes, highly recommend!
I’ve now been using this lash oil for almost a year and my lashes are stronger and longer!
My lash tech loves doing a LVL on my lashes cause of how long they are now.
Truly a life saver for my lashes after always having classic lashes done.
The second photo is before using the lash oil to then a week later and the first photo is today after almost a year of using it.
I used it on just one eye to see if it actually works (so you don't have to!!! you're welcome lmao) and after probably a month of using only 2-3 nights a week (yes I frequently forget) I can see that it's working. I just permed/curled my lashes and I officially have to start applying to both eyes because it's noticeable (probably just to me but still) that one eye has stronger/bolder lashes than the other. Plus it was kind of hard to put on my perm solutions on my other eye, the lashes on the side I've been using the oil on are now long enough that it's easy to glue down but the other eye is too short. I'll maybe write another review comparing the growth to these pictures if I remember but I'm sure once I start on both eyes and more frequently the difference will be really noticeable. Honestly looking at these pictures I started with pretty dark/strong lashes but perming them really makes them pop and using the lash oil helps even more, plus again it makes it easier to glue them to put on the perm lotions. In the pictures, I used the oil on my eye with the brown and didn't use on the all-blue eye.
Also, I usually get irritation or redness from growth serums that I've tried before, so I never could use them frequently enough to see a difference. With the perl oil it's a little irritating if it gets in your eye, which happens from time to time to me but it's not irritating to the skin AT ALL. Which just changes the whole game, now I just apply a little bit so it doesn't run and I can use it every night (if I remember .... lol) Seeing the difference already makes me more motivated to use it too so hopefully that helps me incorporate it better into my routine. Anyway! Definitely 100% recommend. <3
OMG you need this. I used to have bald spots cause i would pick out my eyelashes and after using this product my eyelashes have been so full they look amazing without and with mascara no need for fake lashes to fill my bald spots anymore. HIGHLY RECOMMEND. and it’s so easy to use im literally obsessed <3
I love this stuff for my brows :) It’s easy to use and actually works. My previously over plucked brows are drinking it up and sprouting new hairs! Not working as well on my lashes only because I do believe it’s because the spooly is hard to get to my lash line. Going to use a different brush and I’ll report back! But brows are fire!!!!
i got this a few months ago after having a botched lash lift and my eyelashes are THRIVING. i’ve not had them this long since before i started wearing mascara. they’re stronger, thicker, less fall out and overall incredible. i’m not gonna lie, i was seriously sceptical buying this because of all the lash serums i’ve used in the past having no affect, but i am so impressed and happy w my results. i recommend this product to people with sensitive skin, eyes or thin skin around eyes that can be affected by hormone lash serums. i WILL be repurchasing. mwah, you ate that 💋
I’ve been dealing with so much stress over the past couple months and I have the worst habit of pulling my eyelashes. I came across Perl Cosmetics via an ad on instagram - I’m so glad I did!
My lashes are so much healthier and even started to fill out and the lashes have started to grow back! They’re so much stronger!
Thank god for Perl Cosmetics
I’ve only been using for a few weeks after pulling my lashes out and I’ve already noticed a huge difference!!
The first picture was taken on the 6th of March and the second on the 24th of March!! 🫶🏻🫶🏻
My lashes were so short and damaged after years of lash extensions. This lash oil completely changed them! You can see in the photos the amazing amount of growth.
I never ever leave reviews, especially after using many different lash products and failing with the majority. I have used serums and have always had issues with it causing redness, irritation and increased sensitivity to my eyes. I have not had any issues with this lash oil!!!! Not only has it increased my lash length but it has also thicken my lashes.
