I donโt even understand how this mascara is so good! It is the most long-lasting, smudge-proof AND lengthening mascara there is, I swear. This mascara will not budge all day long. It is 100% waterproof, and definitely requires a good oil or waterproof makeup remover to truly get it off but the extra minute it takes to remove this mascara is worth it for the all day long magic!
