General Science / Is it detrimental to continue to wear a too high sun protection factor?

Having just burned my nose hiking, I've learned the hard way that forgetting your SP cream can cause excessive nasal irritation. So we are advised to wear a high SPF, but can this have a deleterious effect such as not preparing our skin to solar radiation, or excessive reductions on vitamin D? If you were permanently lathered in SPF 40, you'd be as white as a sheet, would you not? This can't be any better than being a bit brown, can it?
