Real People. Real Lashes. No Fillers, No extensions - Just LiLash.

Applying lash serum to upper eyelid with precision brush for longer, fuller lashes

3 EASY STEPS

HOW TO USE LILASH

One application daily along the upper lash line.

Consistency over 90 days is everything.

01

Remove Applicator

Remove the applicator from the tube and wipe off excess serum.

02

Apply LiLash

Apply LiLash Eyelash Serum directly to the upper eyelid skin along the lash line.

03

DRY 2-3 MINS

Allow the serum to dry completely for at least 2-3 minutes.

Highly effective lash growth serum delivering dramatic length and thickness within 2-8 weeks. Customers said "my lashes have NEVER been this long" and praised results over other brands. Most report no irritation, though some experienced eye sensitivity or darkening under eyes. Requires consistent daily application and continued use to maintain results. Pricey but widely considered worth the investment.

Long full curly lashes that won't beat the extension allegations

As a person with short curly lashes I actually have been complimented on how amazing my lashes look and my makeup artist even asked me if i got extensions. I also recommended it to my little sister with straight lashes and the results really start showing at around 4weeks. It's super simple to apply and i keep it next to my toothbrush so i never forget to apply morning or night. If you have curly lashes make sure you brush them with a clean spoolie so you don't find out you have a few that grow backwards (i always had them they were just too short to notice before ). Side note: IF YOU WAKE UP WITH CRUSTY EYES YOU ARE APPLYING TOO MUCH PRODUCT.

When i noticed it was working i bought a second bottle during the Black Friday sale at Amazon on subscribe and save.

I also tested what happens if you stop using it completely and it took about 6-8 weeks to fully revert

Exceptional results! If I could give 1000 stars, I would!

Exceptional results! I wore lash extensions for 15 years and they suddenly started irritating my eyes so I had them removed. My lashes were damaged pretty badly. They were short, sparse and looked horrible. I didn’t want to leave the house!

I tried 3 or 4 different lash serums. They all irritated my eyes and frankly I didn’t see any difference. I was so bummed. I happened to see an ad for Li Lash and decided to do some research. The reviews were consistently high and the ‘after’ pics spoke volumes. So I decided to try Li Lash.

The ad and promos all said I should see a difference in 30 days. Based on my experiences with the other serums, I thought, “yeah, we’ll see”. OMG . . . 30 short days later, I have long, thicker lashes and people are asking me where I get my lashes done because they look so real and are so beautiful! I am your new Li Lash Ambassador! Can’t say enough about the serum. Simply put, It. Works.

Thank you Li Lash!

Lash progress

I am on my third LilLash serum and when I started my lashes were growing back from using a different serum but it was very slow and my lashes were very balding. I changed to LilLash because I was at a stand still with the previous serum I was using for a while. I have seen progress but not fully restored yet but I want to give this serum a chance so I have continued with it hoping my lashes will be fully restored soon.

User for Years!

I’ve been using LiLash for years and it works! Consistency matters and while my lashes have never gone back to being short and scarce, when I use this more frequently it makes a real difference. Once I’m at the length I love, 2-3x a week is enough to maintain. That means my tube lasts and I love that. A little goes a long way, and it’s easy to use and while I can be sensitive to a lot of products, I’ve never had a single issue.

The absolute best!

I’ve tried over 20 lash serums and hands down, LiLash exceeds every single one. My lashes are long and full and I’m asked constantly if I have extensions or false lashes. Don’t waste money on any other product. LiLash is far and away the best!

NEVER TOO OLD FOR LILASH

Li Lash is the third serum for lashes I have used. The first one was the original and it worked but was too expensive to continue using. The second one gave after using for a couple years sowed no new growth. I am 85 years old and felt too old for these serums to work for me. My daughter uses Li Lash with success and gave me a coupon to try it. Week 6 and I am pleased to see and say my lashes are thicker and longer and will reorder.

Magic potion for my “aging” lashes

As I got older my lashes got thinner. My esthetician recommended I try LiLash. After a few weeks I couldn’t believe how well it worked! My lashes were longer and looked more filled in. I’ve been using it now for a few years. I’m a lifetime user for sure! I don’t need to try anything else.

Amazingly works!!!

I am 56 years old & thought I’d have thinning, short eyelashes for the rest of my life. But I’ve been using this a little over a month & my eyelashes are filling in & getting longer. It truly does work!

LiLash FAQ

Are My Results Permanent?

LiLash is a beauty treatment. Continued use is necessary to maintain results. If discontinued, your eyelashes will eventually return to their appearance before use. A 1–2 week break is recommended between treatments to allow your lashes to rest.

How Long Does A Tube Of LiLash Last?

LiLash is available in a 3-month (2 ML) or a 6-month (4 ML) tube depending on the size purchased. With proper application, a tube of LiLash® 2 ML will last 3 months. One tube of LiLash® 4 ML will last six months.

How Do I Use LiLash?

Pick a place to keep your LiLash on your vanity to create a daily habit as part of your beauty routine. LiLash® should be applied once daily to clean, dry skin in the morning or at night before bed. Remove the applicator from the tube and carefully wipe any excess serum on the inside of the tube. Apply LiLash® directly to the upper eyelid skin along the lash line, similar to your favorite liquid liner. Do not apply to your lower eyelashes. Wait three minutes or until completely dry before using any cosmetics or skincare on your eye area. Please review the application instructions included with your LiLash® tube before beginning your treatment. If you have sensitive skin, we recommend starting with every other day application for the first week or two. Link to how to apply blog? Add patch test?

When will I see results?

Some users begin to notice a visible change as soon as 2-4 weeks, with full results typically seen in 8-12 weeks with consistent daily use. Individual results may vary.

What Should I Do If I Get the Product in My Eye?

LiLash is applied to the eyelid skin, not inside the eye. If any product does enter your eye, rinse thoroughly with water. 

What Is Dehydrolatanoprost?

Dehydrolatanoprostis a prostaglandin analog, a cosmetic ingredient derived from naturally occurring fatty acids. It is the active conditioning ingredient in LiLash and is the reason LiLash has been trusted for 19+ years. Prostaglandin analogs are well-studied ingredients used in the lash care category.

Will Applying More Frequently Deliver Faster Results?

No. Applying more than once daily will not speed up results and may increase the likelihood of irritation. Once daily application is all that is needed. Consistency over time is what delivers the best results.

Can I Use LiLash With Eyelash Extensions?

Yes. LiLash can be used with eyelash extensions. Apply to the upper lash line as directed, and avoid contact with the extension adhesive where possible. Many extension wearers use LiLash to support the condition and appearance of their natural lashes underneath.

Can I Use LiLash If I Wear Contact Lenses?

Yes. LiLash is suitable for contact lens wearers and ophthalmologist-tested for safety. We recommend waiting 2-3 minutes or until lash serum is fully dry before inserting contact lenses. 

Can I use LiLash after a lash lift or lash perm? 

Yes. LiLash is compatible with lash lifts and lash perms. We recommend waiting at least48 hours after your procedure before resuming use to allow the treatment to fully set. Apply as directed to the upper lash line only.

Can I use LiLash if I have a lash tint?

Yes. LiLash is compatible with lash tinting. We recommend waiting at least 24 hours after your tint appointment before applying LiLash to ensure the color has fully set.

Can I use LiLash with tattooed or permanent eyeliner?

Yes. LiLash can be used if you have tattooed or permanent eyeliner. If you have recently had the procedure done, we recommend waiting until the area is fully healed before beginning or resuming use. Consult your technician if you are unsure.

Is LiLash nut-free? 

LiLash contains Prunus Amygdalus (Sweet Almond) Extract, which is derived from almonds, a tree nut. If you have a tree nut allergy, we recommend consulting your physician before use.

How do I know my LiLash is authentic? 

Every authentic LiLash and LiBrow product features a numbered hologram security emblem with the LiLash logo on the packaging. If your product does not have this hologram, do not use it. 

To ensure you are purchasing authentic LiLash, buy directly from lilash.com or through one of our authorized retail partners and LiLash Pro spa and salon locations. Purchasing from unauthorized third-party sellers carries the risk of receiving counterfeit or improperly stored product. If you have any concerns about your product's authenticity, please contact our customer service team. https://www.lilash.com/pages/counterfeits

Can I Use LiLash on My Lower Eyelid?

No. LiLash should only be applied to the upper lash line. Do not apply to the lower lash line.

Can I Use LiLash on My Eyebrows?

LiLash is specifically formulated for eyelashes. For brows, we recommend LiBrow Purified Eyebrow Serum, which is designed to condition and support the appearance of fuller, healthier-looking brows. The LiLash + LiBrow Set is a great way to address both.

Does LiLash Contain Parabens?

No. LiLash is formulated to be paraben-free.
