Lilash ingredients: it includes a prostaglandin

Reviewed by Marta June 23, 2010 128 Comments

A reader with intrepid sleuthing skills sent me the ingredients list for Lilash Eyelash Stimulator. I've been trying to find out what is in Lilash all year and the manufacturer, based in Scotsdale, is not very forthcoming. It turns out that the active ingredient is a prostaglandin analogue. Prostaglandin is the drug used to treat glaucoma that - because it may change the color of your eyes or even impact sight - has made eyelash growth products controversial to say the least.

Lilash also contains (in addition to five parabens and phenoxyethanol) a rather unpleasant preservative called methylchloroisothiazalinone. In high concentrations it can cause chemical burns and it is a skin and membrane irritant and so it was largely removed from most cosmetic products except for those with only short duration skin contact such as rinse-offs. There are some newer formulations that make it more acceptable to sensitive users, so it is now found in cosmetics more frequently. In the US accepted concentrations are 15 ppm in rinse-offs and 8 ppm in other cosmetic.


Water, Glycerin, Hydroxyethylcellulose, Panthenol, Lupinus Albus Seed Extract, Prunus Amygdalus Seed Extract, Silica, Methylchloroisothiazolinone, Phenoxyethanol, Methylparaben, Butylparaben, Ethylparaben, Propylparaben, Isobutylparaben, 9 alpha, 11 alpha, 15S-trihydroxy-17-Phenyl 18, 19, 20-Trinor-prosta-5Z, 13E-Diene-1-oic acid, Isopropyl Ester.

    I have used Lilash for least for 7 or 8 that I can remember. When I first started using it, it worked AWESOME. I had the longest, most beautiful eyelashes. It did not change the color of my eyes either. For the last several years, it has stopped working. I knew they must have changed the formula since it doesn't work anymore. I'm so disappointed!! Now I need to find a new one that actually works....if there is such a thing.

    I've had LiLash training with the official LiLash supplier and it is the only lash growth treatment on the market that DOESNT contain the ingredient to change your eye colour. This was also over 4 years ago and it hasn't been added since then. Fake LiLash does, maybe review the real product before scaring people. Not one of my clients in over 4 years has had a problem.

    I do not usually write comments about products. But I thought this might help someone with eylash deficiency. I am a Chiropracter and I'm all about looking your best. And the Lilash product I bought works. My eylashes are beautiful ! I do not look like I smoked weed in the morning as I did with the other prescription brand. I did buy it from overstock because the do not distribute in the USA anymore. What is that about? Hmmm....... Oh yeah control and money!!!

    Hi Donna, this article is from 2010. Lilash has indeed changed the formula since then. But the critical point is that the product still contains a prostaglandin. The only things that have changed are the preservatives. Here's the current list: Purified water, Hydroxyethylcellulose, Glycerol, Sweet Almond Extract (Prunus Amygdalus), Panthenol (Provitamin B5), Hydrolyzed Lupine Protein. Isopropanol Phenyl-hydroxy-pentene Dihydroxy-cyclopentyl-heptenate, Chlorphenesin, Silica, Caprylyl Glycol. The prostaglandin is Isopropanol Phenyl-hydroxy-pentene Dihydroxy-cyclopentyl-heptenate

    The ingredients for LiLash is no where near the ones listed in your article. I have been using the Original Lilash for over 2 years and have had no problems. I have sensitive eyes. I did buy one of the counterfeit and it had the ingredients you listed above. So the one you are reviewing is a counterfeit not an Authentic LiLash. You can always get ahold of the company to find their past distributors for the United States to see if the person you are buying from is the right one or a counterfeit from China. They are counterfeiting everything and it looks Authentic but the products aren't
