Nutraluxe was one of the first and only 3 on the market before 2012. Latisse, Revitalash, and Nutraluxe were the only brands that had a formula that worked. Now, there are many that are too expensive or do not work. I have used this since 2011, and continue to use it daily with light green eyes. No issues, ever. This is a 3 month bottle and you will see great results before the first one is gone!
