The list of ingredients contains lots of good stuff (niacinamide, ceramide, peptide, etc)! The serum is cool and hydrating on the face and feels very "clean" for the fact that it is unscented. On healthy skin it does its job well, but seems to aggravate the areas where I already have a breakout. As it cannot be used on sensitive/breakout areas, I'm not sure if it's effective according to its claim of "soothes irritated skin barrier".
