What are the differences between sun protection products?

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?


How can I stop being afraid of seeing my rapist?

I was date raped by a man who I was seeing. I had broken it off with him a month before, but got into a situation where he attacked me. The problem now is he is friends with many of my friends, and he works at a place I must go to frequently. I haven't told my friends because I don't want them to confront him. I haven't seen the man since he raped me and I am afraid to. I know my friends will want to see him, and I know I will eventually run into him. I guess my question is what do I do when I see him? I don't want to talk to him, but I am afraid he will try and talk to me. I am scared of my reaction and don't want to have a freak out in front of my friends (although I know that they would understand). How can I leave this situation behind and resume normal life, not being afraid of seeing him in my everyday life?


What are the risks of gel and shellac nail manicures?

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?


How can I get over my fear of public speaking?

1) I have been a student for two years now and still suffer from terrible anxiety when it comes to doing a presentation or speaking in class. When it comes to presenting in front of my classmates I become so nervous that I can barely speak. I perspire; there is minimal shaking; feel so embarrassed that it even makes me want to cry. Now I even feel physically ill. It has gotten to the point where I refused to do a presentation last semester and my grade was badly affected. I know everyone becomes anxious in such situations but I truly feel there is something else going on with me because I've had to do presentations before coming to school but never felt this terrible. Even speaking in class is a very hard struggle, and my grades depend on it!

2) I have an extreme problem with speaking in front of groups of people (especially speeches). I can't do them! My voice either doesn't say anything, or it shakes like I am going to cry or something. I know public speaking is like the most common fear, but mine is one I must confront. What kind of options do I have besides books? Any ideas?


Are moles that change color or increase in number a cause for concern?

1) Over the span of the last couple of years, I have noticed a significant number of moles appearing on my body. They have been appearing everywhere from my neck to my inner thighs. I had one on my neck since childhood, but now have so many more. Is this normal? Is it something I should be concerned with? And does child bearing have any relevance to this happening?

2) I have a mole which has turned very dark purple, and grown a bit in size (still small). This is the second time it has done this — last time was a couple of weeks ago, and it slowly faded back to almost nothing until today. Should I be very concerned about this?
