I got another one from @caitatskinandsugar yesterday and it's a great example of how well the eyelash serum I use is working. It's a serum that doesn't use prostaglandins (a lot of the popular brands use it and it can cause discoloration and orbital fat loss - and even change your eye color!) and comes in a large tube. It does take longer to notice a difference, but even just using once a day (directions say twice a day) I've noticed longer and more voluminous lashes in two months. - @goalstogetglowing recommendation.
