Love the formula but not application [SEP] Really love this concealer.  Best concealer for my dark circle that I had found.  But I hate the pen and sponge style application!  It brings up too much for concealing and when not used it smudge the tube and create a mess.  Plus the sponge just isn't sanitary for multi use.  I also noticed that formula become thicker over time vs the sample tube that I got.  Wish they would change the package for an easier application.
