I totally agree with you on this, and I also can't use any commercial sunscreens without developing horrible painful chemical burns. I've tried just about every sunscreen made, and the result is the same, no matter what the label claims. There is one brand that I get at health food stores that is mainly pure zinc oxide that I use if I'm going to be outside all day, and it works pretty well. It leaves white streaks all over everything, and gives my skin a ghostly look, but it's a small price to pay...
I've found that if I gradually expose my skin for increasing amounts every few days in the spring, and spend a day or two at the beach wearing the zinc oxide, by summer I can be at the beach for a few hours, no sunscreen, and no sunburn either. Those of you who know me know how pale I am, so I think this is pretty cool.
My mom likes to point out that the historical increase in skin cancers correlates to the increase in usage of chemical sunscreens... I don't know how accurate that is, but it is food for thought...
Tanning beds are another story, to me they just feel wrong. I love being in the sun, makes me feel great.
I use a mainly zinc oxide based cream on my kids & they look light purple... it's funny but with their skin tone being darker they look like little aliens with the sunscreen on.
I've heard the same thing that your mom says.... also I would like to point out that it also correlates to the "low fat" diet trends. Diets high in the essential fatty acids promote safer sun exposure. When we jumped to low-fat, no-fat and hydrogenated everything, we lost the good stuff with all the benefits, including this.
My skin works the same way in the sun.
This actually shows that sun exposure can also protect you from certain types of cancer.
The thing is you don't find out most times until way later in life when you start developing all these skin cancers that must be surgically removed from your face, back, arms etc., from all the UV exposure you had earlier in life, usually the majority(~90%) of damage is done before the age of 18. Each to their own though. Of course a sunburn is always worse than a gradual tan. That is pretty much a given with most folks. It's fuNNe even if you try not to get sun by wearing a 30, you will get it, like SJ says. Just look at some beautiful people like Nicole Kidman. No one seems to mind the lack of tan on that beauty. ;-)
) but he did when he was younger. He was as brown as a bear in the summers, but his skin is still healthy-looking--he doesn't look like beef jerky, the way I've seen others his age who obviously spent too much time just laying out in the sun.
