Neulash eyelash enhancer contains a prostaglandin derivative

Skin Research Laboratories has revealed that it uses a prostaglandin derivative in its Neulash eyelash growth product. Called isopropyl cloprostenate, the ingredient is an analogue for prostaglandin, the glaucoma drug. Prostaglandins are controversial because they are technically a drug and a powerful one at that.

Used to treat glaucoma, one of the side effects is that eyelashes grow like weeds. Unfortunately, there are bad side effects too such as irritation, harm to vision and the actual color of eyes can change (say from brown to blue).

The makers of Neulash say that isopropyl cloprostenate is completely safe and its efficacy is increased by adding peptides into the mix, specifically in the form of polypeptide-23.

    I experienced pre-orbital fat loss due to Neulash. I used it for two months. I already knew about the dangers of prostaglandin because a friend who is an eye surgeon had told me many of his clients experienced fat loss due to lash serums. Neulash does not disclose this on their package so I thought I was using a safe product. I used to have pretty almond shaped eyes without any bags. Now I have deeply hooded eyes and horrible redness. The redness has diminished since I stopped using the product but the fat loss has not. Every time I look in the mirror now I want to cry. So unless you want to risk having your eyes sink into your face and looking ten years older....DO NOT USE.

    Neulash did not remove the prostaglandin derivative... They just removed it from the packaging. There are others with "new and Improved" who have done the same.

    I have been using Neulast for 6 days, applying it every night. For the last 72 hours, my eyes are red and they burn & itch like crazy. I am afraid to continue using it.

    We have just heard that Neulash is now eliminating the isopropyl cloprostenate which made the product effective. Apparently, the lawsuit posed by Allergan has caused the change in formulation.

    contains a prostaglandin derivative

    Lilash also uses a prostaglandin derivative in its Lilash eyelash growth product and LiBrow brow growth product. Called isopropyl cloprostenate, the ingredient is an analogue for prostaglandin, the glaucoma drug. Prostaglandins are controversial because they are technically a drug and a powerful one at that.

    Used to treat glaucoma, one of the side effects is that eyelashes grow like weeds. Unfortunately, there are bad side effects too such as irritation, harm to vision and the actual color of eyes can change (say from brown to blue).

    The makers of Lilash say that isopropyl cloprostenate is completely safe and its efficacy is increased by adding peptides into the mix, specifically in the form of polypeptide-23. However, the same growth formula is in Latisse formula which requires a physician monitoring patient tolerance.

    Hello, I need to get in contact with people who also got symptoms from Neulash. My eyes are getting worse (barely no tears) and I need to get in contact with their doctors that can help me a.s.a.p. Thank you! eyeproblem@hotmail.com

    I found another product that works called Enormous Lash from Beauty Society (Intuit.) It has none of the controversial drug or derivatives in it and it works so well!!!

    I started to use Neulash two months ago, and WOW, what a difference! Not only have my eyelashes grown, they are thicker and much fuller. Incredible product!

    <p>In February I bought this product and after three months it still wasn't working. I was totally bummed until I saw my sisters eyelashes. OMG! I was so jealous. She used Revitalash. I found it at my local spa - essential day spa. After only four weeks I have longer lashes! </p>
