Glimmr was first known for its superfood-laden hair mask, which is currently on sale, and the brand’s been busy attracting more loyal customers with its effective lash-boosting product. One shopper who called Glimmr’s serum “magic” claimed to see results “in only a week” and went on to call it a “summer essential.” Another “stopped getting fake lashes” after using the product, and a few mention that they’ve tried several other brands, but none stack up to Glimmr’s. “I can’t tell you how many products I’ve tried and for how long I’ve struggled with thin, short lashes,” one customer wrote. “My prayers have finally been answered. After about two months, my lashes became longer to the point that people started mentioning it to me. Glimmr has been a dream come true.” To buy: $50; glimmr.com. Similar to the hair mask, Glimmr’s eyelash serum has a superfood-focused formula, with hydrating and sensitive ingredients you’d find in some of your favorite skincare products. Moisturizing vitamin E and hydrating plant-derived squalane keep skin and lashes soft and healthy, while amino acids serve as the actives, combining to create proteins that repair and strengthen each lash. And the simple application of painting it onto your lash line once a day makes this a pretty seamless addition to your nighttime routine. While you may get lucky with the super fast onset of results like some shoppers have reported, the brand says you should anticipate more noticeable lashes in one month, with the fullest effect at three months. You can pick up the lash-booster for $50 here, or grab the hair mask along with the growth serum as part of a discounted bundle right now for $81.
