I wondered if it would be possible for you to give advice on sun protection? I am British (dark blonde hair, fair skin and green eyes), but five years ago I moved to Australia with my family. At first, because I was worried about the effect of UV on my skin, I followed the 'Slip, slop, slap' advice which is recommended in Australia. However, after a period of ill health I was diagnosed as being deficient in Vitamin D, and my GP recommended that I only use sunscreen after I had spent approximately 20 minutes in the sunshine. So, I reduced my use of sunscreen as per her advice, and only used it if I was going to be out in the sunshine for more than 20 minutes or so.
This morning I had to have a pre-cancerous lesion removed from the skin on my chest.
I just wondered if it would be possible for you to give your opinion on sunscreen/cover up approach for different skin types/colourings, with reference to geographical location and balanced with recommendations for optimal vitamin D production. I would also appreciate your opinion on whether chemical or zinc based sunscreens are best, or whether it is better to cover up or stay indoors instead (not always a comfortable option in 38 degree C heat!). Would it be better for someone such as me (with very fair colouring but living in a harsh climate with a big ozone hole) to take supplements and keep out of the sun/cover up entirely and not depend on it for vitamin D?
