This is a very good water-soluble cleanser for normal to slightly dry or oily skin. The plant extracts are indeed from the sea, but your skin isn't going to notice one way or the other because they're rinsed off. What counts are the standard non-natural ingredients that do cleanse skin, remove makeup, and reduce excess oil.
Although this contains alcohol and some fragrance ingredients the amounts are low enough to not be much cause for concern. Still, as with any cleanser, use caution when applying around the eyes.
