Reviews Summary
Customers say this eyelash serum makes their lashes longer, thicker, and fuller after consistent use. Many report noticeable results within 2-8 weeks, with some seeing changes as early as one week. Users frequently mention receiving compliments and being asked if they're wearing false lashes. The serum is praised for being easy to apply and long-lasting. However, some customers experience eye irritation, burning, redness, and swelling. Several note that results require continued use to maintain. A few users report no visible improvement after extended use.

    Amazing product.

    Received this product from a friend that noticed my lashes were very thin and short. After using the product for approximately a month or so, I started seeing results. They are very noticeable when I curl my lashes. A bit pricey but the product does indeed work and I highly recommend.
