I've come down with chickenpox. Should I stay home from classes even though 90 percent of adults have already had it and are thus immune? If I take great care washing my hands and avoiding coughing anywhere but into the crook of my arm, will I be reasonably assured of not spreading it?

Is there any cure for itching when I wear wool clothes? In the winter time, I love to wear my wool pants and sweaters, but they make me itch. I've tried wearing pantyhose underneath, but it doesn't work.

Help.

I have two piercings in each earlobe; however I have not worn earrings in the second set of holes for several years. Recently I tried to insert earrings into the seldom-used pierce holes. One earring went in with no problem, but the second did not go through after several attempts (I actually gave up because my last attempt bent the earring post). I have tried inserting other earrings but they also will not go all the way through. Is this something I can fix myself? Do I have to get the same hole professionally re-pierced? Will there be problems with scar tissue at the site?

I am African-American, but my skin is not that dark. I was never told that I needed sunscreen and when I worked in a daycare I was told in a very delicate manner that only the paler children needed sunscreen. I've been out in the sun for extended periods of time and was wondering if sunscreen is necessary for someone of my complexion. If so, what strength?

I was thinking of buying a face powder that says it has an spf of 30. It seems convenient to have a powder sunblock since lotions make my oily face greasy. However, I was wondering if this powder will even be effective as a sunblock since I heard that some moisturizers and other products that advertise an added SPF sometimes don't have a high enough concentration of sunblocking ingredients to make it effective. I would like to know what do you think before I make my purchase.

In a recent question about abnormal hair-growth, the writer mentioned a long history of hydrocortisone use as a means of treating eczema. I too have a long history of severely uncomfortable and troubling eczema. During the worst outbreaks, I have visited several different dermatologists, and all have prescribed topical hydrocortisones, such as Hytone or Topicort, as well as anti-itching pills, such as Atarax. One prescribed Diprolene ointment, which I used for a year, until my next dermatologist dismissively told me it was far too strong and could be damaging.

I would like to know once and for all how damaging the extensive and long-term use of any of these creams is. Please give me one of your straightforward answers; I have been frustrated by the differing views and lack of concern among the dermatologists I have visited. I am tired of being told it is "just eczema." I already use the gentlest cleansing products available, tons of moisturizing cream, rinse all my clothes twice, wear soft fabrics, etc. I am still absolutely tortured by itching, often resorting to scratching at my skin with a hairbrush. The eczema reappears without fail in the same places, even on my face, and is particularly bad after stress periods, when I absolutely cannot control my itching or scratching. Isn't there anyone anywhere doing research on this? Is there anything else I can try? I am not averse to vitamin, holistic, or homeopathic therapies, if there are any. Please help. This is really a very ugly and upsetting problem.

When I was young, I had no freckles. As I got older, my face began to form freckles. Also, darker freckles are forming. Is there a way I can remove the freckles or stop them from forming?

I am not actually worried but simply curious. When petting with my boyfriend and getting in contact with his sperm, my skin turns slightly red where his cum touches me. Am I allergic, or is there perhaps any other explanation? I am 24 years old and female.

I read the info on molluscum in the Men's Health section. Are there any signs that distinguish molluscum from genital warts/any way to tell if you have one or the other?

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 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 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?

I fell on my roller blades yesterday and skinned my knee. Now I'm watching my knee change and I am fascinated by the healing process. Could you explain to me just what is happening?

I plan to do some nude sunbathing this summer. What extra precautions should I take with the areas that have never seen the light of day? Should I use a higher SPF on my "naughty parts" than on, say, my arms and legs?

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?

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

I am 21 and have had consistent acne. I have tried topical creams (benzoyl peroxide, Retin-A, and topical antibiotics; as well as oral antibiotics for a number of months before). But, the acne keeps coming back.

For acne, does taking omega-3 fish oil supplements help? If so, how does it help, for what length of time should it be taken, and how many milligrams should one take?

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?

I have a one half inch lump inside the back of my leg two inches above my knee (there is no visible mark on the skin). It is not painful or bothersome in any way. An acupuncturist thinks it is a cyst. If it is, what kind might it be, what kind of treatment might I get, and how necessary is it?

I get cold sores around my mouth and nose all the time; I have since I can remember. I know that they can be caused by both physical illness and mental stress. Is there any way to reduce the frequency with which I get them, i.e., diet? Please help me, I feel like a leper.

I am a first-year student and I want to get my nose pierced. This isn't just a whim; I've wanted one for a long time. However, I know that there will come a time when the ring will look juvenile on me. My question: will such a hole close up fairly quickly, without leaving an ugly scar?

How do tattoos work? I mean, if human skin cells are always shedding and reproducing themselves, how are the pigments of a tattoo able to stay in the skin for so long?

Is it possible to become dependent on moisturizers?

I suffer from dry skin and each Winter go through about half a gallon of moisturizer all over my body by Spring time. It's starting to feel like my skin is getting dependent on the moisturizers, meaning that it always feels like I need them, even if it is a humid season. It's like the skin gave up on circulating its own moisture because it is expecting it from moisturizing cream. Is this just my imagination? Or should I back off on the moisturization?
