Can anyone recommend a good sunblock?

[Guest guest]

I want to use sunblock on my face b/c I don't want to photoage in that area

anymore than I have or have to. I lay out in the sun a few times/week to try

and get my vitamin D in the middle of the day, plus I live in Miami and I do

this in the winter too. I have been getting too much sun on my face lately and

since we all have to pick our battles, I prefer a little toxins once in a while

to wrinkles.

Many of the sunblocks at Whole Food have Titanium Dioxide. According to this

article http://www.organicmakeup.ca/ca/titaniumdioxide.asp, if the size of these

particles are very small they can damage the cell's DNA after sun exposure, so I

want to avoid this ingredient. Has anyone else looked into this and can

recommend a brand?

Thanks.
