There are so many types of eyelash serums that I struggled to decide which one to buy, but this time I tried the Cho Sung Ah Black Bean Keratin Eyelash Serum. Since I use an eyelash curler frequently, I felt like my eyelashes had weakened. When I first used it, I was worried it might be too sticky, but it finished surprisingly fresh, so I was able to use it without any hesitation. I am trying to get into the habit of applying it before bed, and since the brush is easy to use, I am managing my lashes without any difficulty. Most of all, I was most satisfied that there was almost no stinging in my eyes. I believe that with eyelash serums, consistency is more important than expecting short-term results, and since the user experience has been good so far, I plan to keep using it.
