This really is a stunning formulation for the delicate undereye area and has become a staple in my routine very quickly. The formula is so quickly and easily absorbed (as an oily skinned girl I *hate* the sticky feeling some richer eye creams can have) and the applicator means you instantly feel soothed and depuffed as it cools the area. I haven't been using it for long enough to comment on long term effects, but my notoriously dark under eyes definitely seem brighter immediately after use and I'm excited to continue using this and see if this is something which improves over time.
