A reviewer concerned with short lashes gave the “miracle” serum a try and saw “thick and longer” lashes that looked “beautiful and healthy” after just three weeks of use. “If you’re not good with false lashes like me but you want to have glorious lashes, get this stuff and be patient and you will be rewarded,” they added. Another shopper used the eyelash serum for “several weeks” to replace their expensive lash extension routine, earning compliments from their eye doctor, who remarked, “Wow, you have so many lashes!” After scouring the internet, a third reviewer stumbled upon the best-selling lash enhancer and saw a significant difference in length in a few weeks as well. They declared it was “worth every penny.”
