HOW TO USE

STEP 1
Start with clean, dry skin. Remove all makeup or skincare from the lash and brow areas and allow skin to dry completely before applying. Remove the applicator and wipe off excess serum against the inner rim of the tube.

 

STEP 2
Lashes: Sweep along the upper lash line, like a liquid liner. Upper lid only.

 

STEP 3
Let it dry completely before makeup, skincare or contacts. Once a day, every day. Consistency is what delivers results. Sensitive skin?
Start every other day for the first 1–2 weeks.

 

Highly effective lash growth serum that delivers visible results within 3-6 weeks. Customers said "my lashes are the longest they've ever been" and report longer, thicker, fuller lashes. Works across all ages, even 75+. Some customers noted minor skin darkening or itching. Non-irritating for most, doesn't change eye color, safe with contacts.

Best Serum I've Ever Used

I've tried so many serums. This is the only one that works great and doesn't darken my eye lids or hazel eyes. My lashes are so long & full and stay that way.

Best last syrup, love my long lashes

I had the shortest lashes ever ever, My hairdresser recommended li lash, I’ve been religiously using it since 2021 , my lashes are so beautifully thick and long.
People always remarked how beautiful my eyes are, if I was wearing fake lashes, I shared that I use li lash , this is the result, and recommended it to them, they all are currently using it as well.
Li lash isn’t like other lash growth serums. It doesn’t change eye color, so not only will you have beautiful bold lashes you keep your beautiful meyevcolor, and yes it is safe for anyone wearing contact lenses,
Run and place your order people, this is a gold mine for your eyes ❤️🙌😃❤️

The best product on the Market

The best product on the Market. Works by far the best. Lash serum has helped my lashes grow long enough that most people think they are false lashes. Worth every penny spent.

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!

Can’t be without this serum

I’ve been using lilash for years at the recommendation of an influencer. This serum is amazing, I’ve tried many other serums that just did not work or irritated my eyes. Lilash does not irritate my eye and my lashes are long, thick and healthy. I get compliments on my lashes often and when I get a lash lift, the effect is amazing ❤️ lilash is a must in my beauty routine

I will never be without my LiLash serum

I will never be without my LiLash serum. My lashes look absolutely amazing! I am often asked if I am wearing lash extensions and I love telling them how this fantastic product has changed my lashes both quickly and without any unwanted toxic ingredients. I have used other eyelash serums in the past including Latisse…this truly is the best. They do have some good sales occasionally, which is when I like to stock up. The 6 month XL size is absolutely the way to go. I have gifted this to my daughters and close friends many times. If you’re on the fence about this one, just grab one…I promise you won’t regret it!

the BEST!

I am not a high maintenance person but this is a must in my nightly routine, along with LiBrow. In an effort to match my son's beautiful lashes, I started using lilash many years ago. I have tried the competitors but none of them allow the consistent growth that LiLash and LiBrow do...I am a forever fan!

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.

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.
