Grande Lash.

"Grande Lash contains a prostaglandin analog, like a common one is called isopropyl cloprostenate. There are many other ones, but this is a common one, and it can be a problem because number one consumers don't know that, and when they're using it they may not be expecting this irritation, hyperpigmentation that may occur. The irritation and the hyperpigmentation have been reported so much that the FDA has actually issued warning letters to the brand basically informing them they need to be fully transparent, and there have been class action lawsuits against brands like Grande Lash."

"Grande Lash is one of the lash serum brands that contains prostaglandin in their products. These work, but I want you to know the risks. If you are considering an eyelash serum, you need to thoroughly evaluate the label to see if your product contains a prostaglandin. Often times, probably all of the time, this is actually not even clearly listed on the box or the packaging and instead it's only mentioned or hidden in the ingredients label of the packaging."

"A lot of people who have been using things like Grande Lash have not only gotten thicker, fuller lashes, but they've said, 'Why do my under eyes look so hollow?' There was specifically one girl on a podcast who was talking about how all of these people are going for under eye fillers because they feel like their under eyes are sunken in after using these lash serums for a long time. Well, there's actually some truth to this and it's in science."
