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 is not 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
