Lash Serum, Eyelash Serum for Longer, Thicker, and Fuller Looking Natural Eyelashes

This is the best lash serum I have ever used. You begin to notice results in as little as 4 weeks. As a lash artist, I’m always looking for products I can confidently recommend to my clients, and this has quickly become one of my favorites. It’s so easy to add into your daily routine, and I love how healthy, strong, and beautiful my lashes look and feel when I’m consistent with it. If you’re wanting to give your natural lashes some extra love—especially if you’re a lash extension lover—this is definitely one I recommend! It makes your lash lifts look even better. My client started using it and her natural lashes are now longer then her extensions.

I have used lash serums for over 8 years and won’t stop! I started with Rodan & Fields, and lived the results, but when I retired, looked for something less expensive and had been using Grande Lash, and it was fine! I noticed how long my daughter’s lashes were and asked if she was still using Grande. She said her friend raved about Borboleta, and she switched to that. Highly impressed, I order one that day! I have to admit that the first month, didn’t show any difference, but a week or 2 later I could feel the thickness and notice the length was beyond what I had with other serums! There are 1 or 2 lashes on each side that I thought could use a snip, but I won’t do that!! I paid $65 for the 1st, not realizing that I missed the sale at $45. Set it up to buy again when it got to $45, and that’s what I paid for the 2nd! These 73 yr old lashes will be popping

Loving it so far! I have been using this eyelash serum about 2 months and I am loving the results. I haven't had any allergic reactions like some other serums, it dries quickly, and I put one swipe across each top lash line as instructed. I will be buying more! I wish I would have taken before pics with no mascara but this is the result with mascara. The same mascara used in both pictures.

I have seen dramatic results with this lash serum. Doesn’t make my eyes sting either. I highly recommend it for longer lashes!

I had been using Grande Lash for quite a while. And it was working. But I had started to lose lashes and had two huge gaps, one on each eye, that weren’t growing in and very noticeable. I found this after I Googled, “best eyelash serum”. I didn’t ask anyone, didn’t see any ads on FB, never even HEARD of it before. Just my Google search. I was hesitant to drop the $65, but I bought it and got it on September 5th. 3 weeks later the gaps are ALL filled in! I could NOT believe it. It’s been MONTHS since my eyelashes have looked this good! This serum is WELL worth the investment!! My only concern is is that I don’t think it’s 3 months worth. But it is worth it to not ruin your real lashes with fake ones. Buy it, and you won’t regret it!

I was using grande lash serum for a few years and it was working but the Borboleta works sooo much better. My lashes are growing at a quicker rate than the grande lash serum was. I’m on my second container.

I've been using this serum for two months and am happy to say it is working for me. This is the only lash serum I have tried, so I do not have a comparison point for other products. This serum has grown my lashes substantially - my lashes are naturally short, straight, and do not hold a curl for long. After using Borboleta for two months, my lashes are approximately 25 - 30% longer than they used to be, have a curl at the tips, and easily hold a full curl after crimping.If I wear mascara the difference is dramatic - it almost looks like I'm wearing extensions!The only downsides I can share is that there is darkening at the application point - it almost looks like I'm wearing a subtle eyeliner along my top lid. Additionally, my eyes are very sensitive so I offset any potential discomfort by using the serum overnight.

Loving this lash serum so far! I’ve used it for about a week now, and have noticed it doesn’t leave any redness on the eyelids like other lash serums do! It’s also completely lash extension safe, which I love! Would definitely buy again!

I have been using this product every night for almost 12 weeks and my lashes have almost tripled in size that I actually had to trim them they were getting to long as they were touching my glasses. The lash serum didn't really thicken them just made them longer which is perfectly find

This has to be one of the best lash growth serums, ever.I had done a fair bit of research before buying the product back in October. I was skeptical as the reviews and pictures…well you never really know.I have generally long eyelashes, but I had used a mascara which caused them to thin and fall out.I have been using this product since 29 October 2025. At first, I would apply it twice a week, at night. At first, it felt like I cried through the night and my eyes were slightly red (as with some products, that can cause you to have reactions. But that happens with anything in life right, a bit uneasy at first.) But after a few uses it stopped.I started using it more regularly, and then bumping it up to twice a day; once at night and one in the morning (before my mascara).I have noticed a MASSIVE difference, holy smokes, I’m not over exaggerating because I’m big on reading reviews. But this is an incredible serum, worth every dollar.I took a picture the first day (for a before) also have pictures with mascara before using it. And to-date (2 February 2026).Also, I have used every Mascara imaginable to man, and in my images, I have pictures with the same mascara on (Clinique High Impact, it’s quite a simple mascara compared to Maneater by Tarte and Better than Sex), this is for context so you know that those two mascaras actually give you a false lash look as opposed to the Clinique. But, you have to see my results.I think I will use this product until the day I die 😅, they probably will still be growing in my grave! My eyelashes are even thicker and back to the length they were when I was 18! I’m 33 now 😅.Okay, I hope you buy this :).

I don’t ever review stuff I buy but this stuff actually works. I have tried revitalash, lash boost, grande lash and Matisse and this stuff is better than those ones. I was skeptical but would highly recommend it!!!! It didn’t make my eyes irritated at all but now I have nice long lashes! Just give it about 3 months to work since lash growth cycles are very slow. That’s how long I have been using it.

I love this lash serum.I was skeptical at first because I had really thin lashes as I'm in my 70's. I am happy to say that I've actually seen good results after a few weeks of daily use. They have definitely grown longer and a little thicker. I'm excited to see what the next few weeks are going to look like.

I’ve tried many different lash serums, but none of them caused as much discoloration around my eyes as this one. Within just a few days of using it, I could visibly see the skin around my eyes getting darker. I also didn’t notice much of a difference in my lashes. I wouldn’t recommend this product.
