Your... face doesn't need sunscreen? That's the opposite of my experience!

I know people that would easily get sun burnt on their nose. I suppose certain parts of your body would be more sensitive to the sun but I'm not certain what causes that. hoping someone with more knowledge and chip in.

I apply sunscreen to all parts of my body if I'm going out to the sun for long periods of time. I haven't noticed certain parts of my body being more sensitive than others either.

slight tangent: Dermatologists all recommend against tanning and especially recommend wearing sunscreen if you're going to be at a higher than 3/4 UV indexed sunlight for prolonged periods of time. It damages skin and encourages skin cancer.

It's better to be safe than sorry. Apply sunscreen often and all over. Appearances are only skin deep. Also spray-on sunscreen is junk. Use a liquid sunscreen that is a minimum 50+ SPF.

I don't use sunscreen on my legs, because they're so Goddamn white I swear they reflect the sun's rays right back at it. I can sit in the sun for hours and you'd never know it looking at my legs.

Even though you say you are laying on the floor, I do believe those areas receive more sunlight. Shoulders in particular can be hit by sunrays whether you are lying on your back or on your stomach. Additionally, it might not be much, but any time you spend standing makes the shoulders receive much of the light directly.

So are you saying that in your daily life you never walk around with your shoulders or arms exposed?

And are you saying that your arms/shoulders are more apt to burn than the rest of your body, or you notice that they tan more easily?
