An all-natural, prostaglandin-free eyelash growth serum and eyebrow growth serum that strengthens lashes and encourages longer, thicker, fuller lashes and brows. Castor oil, rich in ricinoleic acid, nourishes each hair from root to tip and helps stop breakage, while light fractionated coconut oil keeps it from feeling thick or sticky and natural vitamin E protects the delicate lash line. Fragrance-free and water-free, so there are no preservatives near your eyes, and the mascara-style wand puts it right where you want it, for women and men alike.

Love this product! I have really seen growth in my eyelashes! I use a little every night and I love that the ingredients are so clean. This is my second bottle. Will definitely buy again.

I've only been using this product for a week or so. I may be seeing a bit of growth with my lower lashes, or it could be my imagination, but I have no doubt the product is nourishing my top and bottom lashes (a win-win), and perhaps there will be some thickening with the bottom lashes as a result.

Amazing product for brow growth !!

Can't be more thankful I purchased this product!! I purchased it specifically for the purpose of eyebrow hair growth and I was so pleasantly surprised. I've been struggling for years to grow back the hairs I lost when I overplucked, and after trying product after product and oil after oil, this has finally answered my prayers. It took about a…

week to start seeing results and ever since, I see new growth and new little hairs popping up every single day. I will begin testing this product on my lashes to see if it works, which I expect it will. 10 stars if I could for this product !! Worked amazing for me !! :-)

I love putting this on before bed and my eyelashes are very healthy. Be aware that it may get into your eyes, but it should only make your vision blurry if you're not wearing contacts since there are no alcohols in it. I would just make sure to wash your face throughly when you get up and flush your eyes…

I like this product

I like this product! At first the oil is a bit intense but it soaks into the skin fast. I also feel like my lashes and eyebrows look fuller and healthier.

I noticed that if I forgot for a few days they didn't seem as nice so trying to remember every night

This seems to be working very well for me. I have thyroid issues and that means thin eyelashes and eyebrows. I noticed that after only 10 days my eyelashes are getting thicker and longer, my eyebrows are filling in a bit as well, I think that they are not growing as much because I put it on before bed and…

it probably gets wiped off as I sleep on my side. I noticed that if I forgot for a few days they didn't seem as nice so trying to remember every night! I understand that if you stop using it you return to previous state of hair growth. I recommend this product and will be buying it again.

Will re-purchase over and over!

I had originally ordered this product a few months back and didn’t see major results. However, I was sent another bottle and wow what a difference!!! My eyebrows and eyelashes have improved/grown so much and because of the product’s natural ingredients, it took a bit longer. I highly recommend this serum to anyone looking for fuller more voluptuous eyebrows/eyelashes. I…

Frequently asked questions

How do you apply eyelash serum?
At bedtime, apply a very small amount of Isabella's Clearly LASH to the tips of your lashes, and to your brows if you like. Less is more: the serum travels down the lash on its own to moisturize the whole length. Use it daily for best results.
Does castor oil make eyelashes longer?
It makes lashes look longer and fuller. Castor oil conditions each lash so it is glossier and less likely to break, so more of your lashes reach their full length. Isabella's Clearly LASH works best used every night.
How long does eyelash serum take to work?
About 2-3 weeks for softer, shinier lashes, and about 6-8 weeks of nightly use of Isabella's Clearly LASH for a fuller look, since lashes grow in cycles. A before photo helps you see the change.
Is Clearly LASH eyelash serum prostaglandin free?
Yes. Isabella's Clearly LASH is just castor oil, fractionated coconut oil and natural vitamin E, with no prostaglandin analogs, preservatives, parabens or fragrance. Many shoppers choose it because prostaglandin lash serums are linked to side effects such as darkened eye color and eyelid irritation.
Can you use eyelash serum on eyebrows?
Yes. Brush Isabella's Clearly LASH onto brows at bedtime along with your lashes. It helps over-plucked or thinning-looking brows look fuller and better groomed, and it conditions laminated brows.
Is Clearly LASH good for sensitive eyes?
It was made with sensitive eyes in mind: no fragrance, essential oils or preservatives. Apply a tiny amount of Isabella's Clearly LASH only to the tips so it doesn't run into your eyes, remove contact lenses first, and rinse with water if some gets in. Stop using it if irritation occurs.
Can you use eyelash serum with eyelash extensions?
Oils can loosen extension glue, so we don't recommend applying Isabella's Clearly LASH over extensions. Many people use it between sets or after removal to condition their natural lashes.
Can I use lash serum after a lash lift?
Yes, once the lift has set (wait 24-48 hours). Oils condition lifted lashes, which can get dry after the perm solution, and Isabella's Clearly LASH also works on laminated brows.
Which should I choose: castor oil or a lash serum?
Plain castor oil is cheap but thick, sticky and easy to get in your eyes. Isabella's Clearly LASH gives you castor oil in a lighter blend with fractionated coconut oil and natural vitamin E, ready to use in a mascara-wand tube, with no prostaglandins.
How long does eyelash serum last?
About three months. You need only a tiny amount each night, so one 0.3 fl oz (10 mL) tube of Isabella's Clearly LASH typically lasts about three months of daily use.
