Q. My skin has been breaking out since I entered menopause. Why is this happening, and what can I do about it?

A. Many women notice changes to their skin at menopause. For some women this means dryness, age spots, or a tendency toward bruising. For others, estrogen levels drop while male hormone levels, such as testosterone, remain the same, which can prompt acne breakouts.

Q. I have a lot of varicose veins. Do they present any sort of a health risk?

A. Varicose veins are typically viewed as a mild, non-life-threatening condition that is more of a cosmetic annoyance than a serious health problem. That said, varicose veins can be associated with some health-related issues, such as swelling in the legs, blood clots, or damage to the skin caused by pressure from the veins. They may also make you more prone to skin damage, infections, and ulcers.

What Is It?

A tic is a sudden, rapid, repetitive movement (motor tic) or vocalization (vocal tic).

There are two main types of tics:

• Simple tics involve one muscle group
  • Simple motor tics include head shaking, eye blinking, sniffing, neck jerking, shoulder shrugging and grimacing. These are more common.
  • Simple vocal tics include coughing, throat clearing and barking.
• Complex tics involve more than one muscle group
  • Complex motor tics include self-hitting or self-biting, jumping and hopping, and twirling while walking.
  • Complex vocal tics include repeating words out of context, echoing what someone else said and speaking obscenities.

Tics sometimes change over time from one simple type of tic to another or from a simple to a complex tic. Some tics are slow and sustained rather than brief and rapid. Some involve the lower body.

Q. I have terrible dandruff that just doesn't seem to ever clear up. What can I do to treat it?

A. For most people, using a dandruff shampoo once or twice a week can control this annoying condition, in which the skin on the scalp becomes dry and flakes off. But in some cases, the condition doesn't clear up and actually requires medical attention.

Eczema is an itchy rash that's often hard to get rid of. Most people can't help scratching it, which further irritates the skin. Eczema is often, but not always, related to allergies. A common cause is your skin overreacting to everyday irritants, such as dust, soaps and detergents, or even dry, cold air, which triggers an intensely itchy allergic reaction.

Skin affected by eczema becomes dehydrated and dry easily, so treatment involves rehydrating the skin. Baths and showers must be short and not too hot. Afterwards, gently pat your skin dry and promptly apply moisturizers while your skin is still moist. Thick creams that lock in the moisture help the most. Be sure to choose creams or lotions without fragrances or preservatives. Limit the use of soaps and shampoos, too. These products remove the skin's natural oils and worsen dryness. And over-the-counter oral antihistamines can help with the ferocious itch.

A widely-advertised facial moisturizer claims to be the best on the market — and sells for $225 per bottle. Should you buy it? Another brand offers a complete skin care regimen — but it comes in 10 different bottles of lotions and potions that all need to be applied daily. Is it worth your time?

Despite manufacturers' claims, many cosmetic products will remove more cash from your wallet than dirt and oils from your skin. You don't need an expensive or lengthy skin care routine — and the good news is, the most effective and reliable regimen is also quick and inexpensive.

Learn to spot an actinic keratosis before it becomes cancerous.

About 58 million people have at least one actinic keratosis (AK), a precancerous skin growth caused by too much sun exposure.

Yet most people don't see the potential danger in these lesions because they are small, with few if any annoying symptoms, and can go away almost as fast as they appear.

Although some sun-blocking chemicals may enter the body, there's no reason yet to change sunscreen practices.

Some common sunscreen ingredients are under new scrutiny. In May, researchers announced results of a study finding that some of these commonly used chemicals are absorbed into the body in higher amounts than previously known. The FDA now plans to investigate whether these common ingredients are still safe at these higher levels.

"This study reminds us that even products we put on our skin have the potential to be absorbed throughout the body," says Dr. Jennifer Lin, an assistant professor of dermatology at Harvard Medical School and co-director of the Melanoma Risk and Prevention Clinic at Brigham and Women's Hospital. Even so, the study didn't find that these chemicals are harmful or that sunscreen is unsafe.
