Water texture absorbs quickly, no stick

Love this. I've had a few different vitiman C and they have been thicker consistency that leave the face shiny and sticky. This is a water consistency and absorbs nicely to the skin. It leaves it with a little shine but I like it. Nothing crazy like the others I've tried. Doesn't leave the face sticky.
