I hope that it does not sound patronizing when I say what a well-researched and beautifully written article this is, and I look forward to Part II.
I also found it quite depressing because after 50 years working in the cosmetic industry, I have long felt that my most worthwhile contribution has been in the formulation and promotion of sun protection products and in particular, my work with inorganic sunscreens.
Now, John Stanek is making me question that belief. I shall read it again, more slowly and with attention to some of the articles referenced.
