I have this concealer in 35 Deep which is actually lighter than 30. This is one of the best concealers for concealing under eye circles I have ever used. It has a super light texture and is long lasting. I apply it with the doe-foot applicator and blend it with my ring finger using a tapping motion. The coverage is medium and it is long lasting. It looks so natural which is why I love it so much. Its not great a covering blemishes and spots but I would use a thicker and more opaque concealer for that purpose. I would highly recommend this product as an under eye concealer.
