Isopropyl Cloprostenate

Official CosIng Information

Details

synthetic prostaglandin analog that belongs to the same class of actives used originally on glaucoma patients. As a side effect, people noticed longer and stronger eyelashes so prostaglandin analogs made their way into eyelash growth products. 

Isopropyl Cloprostenate does work when it comes to eyelash growth, however, it is not without possible side-effects and is kind of a controversial ingredient. An FDA-warning letter mentions among others ocular irritation, hyperemia, iris color change, macular edema and ocular inflammation that may happen and the FDA is generally not happy about prostaglandin analogs being used in cosmetic products.
