I use 30 as well but after a couple of weeks I drop it to 15 (I stay a month) depending on the sun's intensity. I use L'Oreal (sp?) 30 for the face - a separate one from the body. It has moisturizers and is dry to the touch in about 15 minutes. And YES I get a great tan. I'm one of those people who stay mostly in the shade too unless I'm in the water of course.
