Fed up with false eyelashes, extensions, and serums that just don’t quite do the trick? Forget the fuss and grow your own naturally lush lashes. This deep-conditioning lash serum uses a unique blend of peptides, vegan stem cells, vitamins, and amino acids to fortify and amplify the appearance of lash length and fullness...and it can even be used on your eyebrows! When applied nightly, this proprietary formula moisturizes dry, damaged lash & brow hairs while maximizing the appearance of lash volume with each growth cycle. Expect fabulous, flutter-worthy lashes in just 60 days. This product may be used on both eyelashes and eyebrows. However, the 3 month and 6 month supply estimate is based on using Lash Therapy only on your eyelashes. Using on your eyebrows as well will mean the product will not last as long.

Lashes 101

About Your Lashes

Aside from being your favorite fluttery accessories, each eyelash is actually a sensory hair that reflexively shuts the eyelid whenever it is touched by dirt, dust, or anything else that could get in the eye. The upper lid typically has about 100 to 150 lashes, while the bottom has between 70 and 100 lashes. Most eyelashes grow to be about 10mm long (just over 3/8 inch).

The eyelash growth cycle has three phases.
Anagen (Growth) Phase

This is the phase when lashes are actively growing, and it lasts between 30 and 45 days. Only about 40 percent of the upper lashes and 15 percent of the lower lashes are in the anagen phase at any one time. Each lash will grow to a specific length and then stop.

Catagen (Transition) Phase

During this phase, the lash stops growing, and the hair follicle shrinks. If an eyelash falls out or is plucked out during this phase, it won’t grow back right away because the follicle needs to complete the catagen phase before it can move on to the next one. This phase lasts between 15 and 20 days.

Telogen (Resting) Phase

This phase can last more than 100 days before the eyelash falls out and a new one begins to grow. Because each individual lash is in its own phase of the growth cycle, it’s normal for a few lashes to fall out most days. It typically takes between four and eight weeks to fully replace an eyelash.


Easy to Apply

  • 1Cleanse and dry your face before applying.

Best lash serum!!!

I have tried several lash serums and this one is by far the best! I get so many compliments on my lashes and I fell good using a natural product. I have had zero side effects. No redness, eyelid turning brown, etc. pure magic!

Better than Lash Boost!

This is the best lash serum I’ve ever used, and I’ve tried 3 of the top recommended ones. They are SO LONG and actually thick. Will continue to buy for the foreseeable future.

The best lash serum

I’ve used many lash serums in the past and have found them to be very irritating. One of the bigger brands actually started to cause discoloration in the white of my eyes, loss of fat under my eyes and lash line. I’m so happy to have found this serum! The ingredients are transparent and I’ve had no issues! Definitely will continue to use and recommend to others!

Holy Growth!

I have noticed a huge difference in the length of my lashes and have been using consistently for 2 months now. I have had zero irritation. I apply after I wash my face at night, let sit for 2 minutes, then apply my skincare. Very happy and will continue to use.

Lashes for DAYS!!!

Lash Therapy has been the solution for my lashes!! I love just throwing on a little mascara and having amazing lashes! They are longer and fuller and it makes getting ready easier and I don’t have to use fake lashes or extensions. 100% recommend.

Nicole B.
I finally have lashes

I have always had short, stubby, light eye lashes. I’ve followed women using this for a long time and never pulled the trigger. My husband bought it for me for Christmas and wow! The difference in just a couple months was crazy! I can’t stop looking at them because I finally have visible lashes! Great product and would highly recommend!

Maryam M.
quite literally unbelievable

I just had a major surgery and the first question the nurses asked when I came to was who does my eyelash extensions because they look so natural. Once they got past their disbelief that they aren't extensions they both bought the lash serum on the spot -- and this happens to me honestly weekly. If this serum existed for scalp hair........ girl... I would be UNSTOPPABLE.
Pic attached is: before first use, after 30 days, and after 60 days. They have gotten even longer since but I stopped photographing the progress once it became clear it works.

Alexis Q.
Holy Lashes!

Wow!! I’ve been using Lash Therapy for 2 months now & I cannot believe the dramatic difference! My lashes have so much growth & they look amazing! Another huge perk is I experienced Zero side effects, no irritation, no itching, no red eyes, etc during this entire process. I am thrilled with my results & I’ve even had friends ask if I was wearing false lashes! Win!!

Leigh B.
Definite lash improvement

I thought I saw great results after just 30 days… but, my lashes look longer and fuller even more! 🤩
