What SPF are you using of NO AD? I only use the SPF 45 since it costs the same. It was rated the same as the rest by Consumer Reports.
On Saturday's I often umpire 3 little league games, so I am out in the sun for 8 hours then, plus take blood pressure medicine that makes me more sensitive to the sun, never burned or even got red with No Ad (or any other brand for that matter). I reapply every 2 hours.
