In some parts of the country, 10 minutes of midday summer UV-B rays on exposed legs, arms and faces can make up to 10,000 IUs. No matter what our skin type is, the time of year, the latitude where we live, what we eat, let's face it: we all will be healthier if we get more not less outdoor activity, irrespective of whatever supplements we take. ...
Again, for certain skin types at certain latitudes, melanoma is a genuine concern, particularly with our still-compromised protective upper atmosphere ozone layer. Skin cancer is rampant in Australia, and we see a lot of it here in southern California, as well.
