There is a strong history of skin cancer in my family so I have always worn SPF 15.  My doctor told me that anything above that is useless.  Same doctor diagnosed me with a Vitamin D deficency that was making my arthritis worse and said the sun block does block the Vitamin D we would otherwise absorb from the sun.  I have a tendency to sunburn quickly but have had no problems with SPF15.    Doctor put me on a prescription strength Vitamin D and I have more energy and the pain from the RA is much easier now.  Hope this helps answer your question.

Denise,

Thank you for your feedback. Think I will cut back on sunblock.

By the way, how are you doing now?

Take care,

I thought, and don't quote me on this, that Dr. Lisa said to go out for 10 minutes, unprotected to get the vitamin D.  Any more then that, use sunblock.  I haven't heard that over 15SPF doesn't work? hmmm .  I use SPF 45 sport because especially in the summer when I hike.  My makeup is SPF20 and it seems to be fine.

Cheers,
