Yeah, my experience jibes with that too. I wear sunscreen everyday and I feel like I'm pretty conscientious but I end up getting red by the end of the day often. The problem with it, i find, is that it's time consuming to do one's exposed skin properly or it involves another person. I'm either working or recreating outside so I know I miss applications due to impatience and inattention. I switched to pants, hats, and long sleeves for outdoor living the past decade or so and it's a huge improvement. Just sweatier.
