Review title is So Far So Good [SEP] *Free or Discounted Sample Provided for Review*<br /><br />My wife has recently began using this growth serum on her eyelashes. Typically it takes several weeks to see visible results. I have taken a before picture and will update this review in several weeks with a before/after comparison.<br /><br />Importantly, she has had no negative reaction to the serum in the first few uses. The brush is easy to use to apply the serum precisely to the eyelash follicles without getting it in your eyes.
