I was recently diagnosed with impetigo & was wondering if I had oral sex with my boyfriend if he'd get genital herpes. Thanks!

I was in the sun for seven hours yesterday and I got a pretty bad sunburn. My face has blisters all over it. The redness is severe, and the pain is severe. Any suggestions that you may have will help. To top it off, I am a diabetic and am worried about infection of the blisters.

I find choosing among all of the available sunscreens and sunblocks to be very confusing. Of the following three products I am currently using, which one is giving my skin the most protection: sunscreen SPF 30 with UVA, UVB, and IR sun protection; sunblock SPF 17 with UVA, UVB, and IR sun protection; or, sunblock SPF 50 with UVA and UVB sun protection? By the way, what is the difference between a sunSCREEN and a sunBLOCK?

I love getting my nails done with a gel or shellac manicure. The polish doesn't chip at all and stays shiny for weeks. I'm just worried about the UV light used to seal the manicure - it is almost like a mini tanning bed for your hands. What are the risks? And are there any bad chemicals in the polish?

For a number of years I have had acne from waist down. I can't find any information on it except for acne of the face and back. I'm embarrassed to wear shorts in the summer. Any suggestions?
