i use as much spf 55 as i can find. i go through 7-8 bottles a summer. but then again i work outside. most people don't use enough. you're not getting the actual spf listed on the bottle if you don't use the proper amount. about an ounce every 4 hours. i can't remember what i was using on my body last year, but it had anti oxidants in it, something oil free on my face and redken's uv rescue oil in my hair. i have something new from clinique for my eyes and lips this year too.
