About one in 10 people has eczema, a chronic inflammatory condition that leaves skin dry and itchy. People with more severe forms may experience a scaly rash or skin that cracks and oozes. These people may also be at greater risk for heart attack and stroke, according to a study in the May 23 issue of The BMJ.

For the study, researchers analyzed data from more than 385,000 adults with eczema, which was classified as mild, moderate, or severe. Each was matched with up to five people of similar age and sex who didn't have eczema.

Q. I am 65 and have noticed a decline in the quality of my fingernails. Should I worry about some underlying medical condition?

A. For the most part, changes in fingernail shape and appearance are simple signs of normal aging and are nothing to worry about. Fingernails naturally grow slower as we age, and their appearance may change, too. Nails can become yellowed, dull, and brittle. They may develop tiny longitudinal ridges and become thinner and more fragile. You can't do anything about these kinds of fingernail changes, but you can reduce the risk of splitting and breaking that often accompanies them. For example:

Q. Should pregnant or breastfeeding women and their children use sunscreen?

A. The American Academy of Dermatology recommends that people avoid applying sunscreen to the skin of babies younger than 6 months of age, and instead shield them from the sun, keeping them in the shade as much as possible. It's also a good idea to protect them from the sun using clothing, hats, and sunglasses.

When it comes to skin cancer, there's good news and bad news. First, the bad news. A report published in the June 2017 Mayo Clinic Proceedings found that cases of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) skin cancers have risen 263% and 145%, respectively, over the past decade.

The good news? BCC and SCC are rarely life-threatening and they're usually easy to treat if they're caught early. Plus, there are simple ways to prevent them.

Q. I was recently diagnosed with eczema. Is this condition treatable without the use of steroids? I'd like to avoid using them if I can.

A. Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition. Some people with eczema have mild dryness or itchiness, while others experience more severe symptoms, such a scaly rash or skin that cracks and oozes. Eczema is more common in childhood, affecting up to 20% of children, but it also affects adults. The good news is it's not contagious, and in some cases, it's possible to manage the condition without using steroids.

As you get older, you might start to look a little more intently at the rows of lotions and potions at the drugstore and the beauty counter. You may wonder which ones can really help your skin look more like it used to — minus the wrinkles, dark spots, and other signs of aging.

One word that's showing up on labels a lot these days is "serum" — typically on products that promise to brighten and smooth your skin and help roll back the clock. These little glass bottles contain a host of impressive-sounding ingredients such as hyaluronic acid, niacinamide, and L-ascorbic acid. But do they really work?
