How much of the body has to be exposed without cover to get enough Vitamin D? Ten minutes is always the time I find when researching, but I cannot find out how much of the body has to be actually exposed.

Do progestin-only birth control pills cause acne, or should I be concerned about Polycystic ovary syndrome (PCOS)? I did not have acne when taking a combined pill.

In 1989 I had breast cancer, my hair came out and never fully came back to it’s original fullness. As of now I wear wigs. Is there anything else that I could do as far as vitamins or diet are concerned? I had chemo, went through a period of menopause for a year, but, I had no other problems. I am healthy.

I am losing hair. Do I need to start using Rograine or is it a temporary result of:

• A new diet started in last month eating 2/3 fruits and vegetables for every 1/3 protein and grain
• Dental work in last month - crown followed by root canal - many x-rays
• Menopause - I stopped over 10 years ago.

What should I do?

As I get older I seem to be developing more skin tags. Is this something to be concerned about? They aren’t misshapen or colored funny, just skin colored tags. Can I just clip them off?
