First off, WELCOME to the Hypography forums Myskran! I hope you stick around and add to our community!
It is just that we have been having problems with anonymous posters recently, and it is being over used a little. Nothing against you in particular. We are currently debating if we should continue to allow anonymous posting or not.
I have made a post
here addressing these problems, so maybe that will clear it some and prevent misunderstandings like this from happening (as this was - just a simple misunderstanding). At the least, posting a name at the end of the post would help a lot
Now to your question. Like Tormod, I'm no expert in dermatology, but I do believe that UV light is required for a body to function properly. I will try to find some more info on the subject for you.
