Okay so BE ADVISED this product worked the first time I used it and then stopped working every time after. I didn’t even wait long before the first application because 2 weeks later I used it on my mom. I did some research and found that lash lift products stop working when they become oxidized. It only take being exposed to 12 minutes of open air to be oxidized. Obviously my bottles have been exposed to this time already. It might be ultimately cheaper to just go get your lashes done somewhere than to keep buying kits. Or perhaps invest in a kit that comes with little individual packets such as Elleebana. Or just be very quick and maybe lay out some of the solution in a plate or something so you don’t keep your bottles open for long.
