Review title is So Far So Good [SEP] I can't speak to effectiveness as that will take longer than I have been using it (will update review), but so far so good. If you have a steady hand, this is simple to apply. I only used it once on eyelash area as I am waiting to hear beck if this formula can have a side effect of turning the iris brown (not a concern if your eyes are already brown), as some formulas have that potential. For the moment I am focusing on the eyebrows. Color, consistency, and ease of application are all good, just use care when using eyelash application, as this can smart, and nobody likes getting poked in the eyeball. No problem it you are good with liquid eyeliner.
