neuLASH is a popular eyelash enhancer serum formulated with polypeptides, hyaluronic acid and conditioning ingredients to fortify lashes. It also contains pumpkin seed extract, which is rich in lash-essential vitamins and minerals.
We had to do some digging since the company does not post its complete list of ingredients online. What we found: Like some of the other top eyelash serum products we tested, its ingredients may cause unwanted side effects. neuLASH contains a prostaglandin analog, which has been shown to cause sensitivity, change in iris color, drooping of the eyelids and even infection. This ingredient, along with other types of prostaglandins, is banned in Canada.
