Today it's hard to get any sunscreen which is not a complete sunblocker so people want to get _some_ sunlight just avoid some sunscreen altogether.

Yeah, I hardly see anything under SPF15, which lets 1/15th of the light in (6.7%). I'd be interested in using an SPF 5 or so (1/5th or 20% of sunlight gets in).

Because those are usually sold as tanning lotions instead of sunscreens. A little bit of protection so that folks don't burn as easily.

But these usually contain chemicals that burn your skin to make them look brown? Like the oval office orangutan clown?
