With summer approaching, you need to be more attentive about sun protection.

Men have many skin challenges as they age. They develop wrinkles, lines, spots, and discoloration. Older men also are at greater risk for the two most common skin cancers: basal cell carcinoma and squamous cell carcinoma.

Without adequate sun protection, these conditions can become more frequent and severe.

In rare cases, people who have had cosmetic dermal fillers experience swelling after receiving the COVID-19 vaccine, but this shouldn't stop people with fillers from being vaccinated.

Polycystic ovary syndrome is the most common cause of infertility in women. In many cases, women with PCOS have skin and hair issues such as acne, hair loss, or excessive hair growth in places where they normally do not have hair. Treatment options vary depending on the symptoms and each woman's preferences.

What to do about prickly heat, poison ivy, and other uncomfortable skin reactions.

Sunburn is a big risk in the summer. You know the rules: seek the shade, wear protective clothing, and use a broad-spectrum sunscreen (with an SPF of at least 30). But sunburn isn't the only summer skin problem.

Plant-related rashes

Many people are allergic to urushiol, an oil found in poison ivy and poison oak. Exposure occurs when you touch the plant directly, maybe while gardening, or indirectly, by touching an object that's picked up the oil (like a shoe). You can spread the oil wherever you touch your body until the oil is washed off. Two to 10 days later, the affected skin develops a red, itchy, blistering, oozing rash. It's not contagious, though you may feel like it's spreading. "The allergic reaction continues to unfold even after you've washed off the oil," says Dr. Jason Frangos, a dermatologist at Harvard-affiliated Brigham and Women's Hospital.

On call

Q. Years ago, my doctor told me a skin growth on my back was a seborrheic keratosis. Now I have more, and they seem to be multiplying over time. Is there any way to prevent them?

A. Seborrheic keratoses are raised, rough lesions that appear as a waxy brown, black, or tan growth. This common skin condition often shows up after age 50 on the trunk, back, face, or neck. The good news is that even though keratoses can increase in number over time, they aren't cancerous or contagious.

Misinformation about sunscreen is common. Don't let myths deter you from using it to protect your skin.

If you've ever searched online for information about sunscreen, what you found may have made you feel less than sunny about slathering on these lotions and creams. Sunscreen is designed to protect your skin from the sun's damaging rays, but some of the claims made about it suggest it could do more harm than good.

Assertions include everything from statements that sunscreen is ineffective to warnings that it's outright dangerous. Some writers even go as far as to state that sunscreen may cause skin cancer, thanks to a purported harmful cocktail of toxic ingredients. That's enough to darken your day.

Ask the doctors

Q. I'm very allergic to poison ivy. My spouse currently has a bad poison ivy rash that he got while trimming some bushes in our yard. I'm afraid I'm going to get a rash from him. Is it contagious?

A. Good news: poison ivy rashes are not contagious. You will get a rash from poison ivy only if you come into contact with urushiol oil, which is the plant oil in poison ivy that triggers the rash. In addition, a poison ivy rash, even one with open blisters, won't spread to other areas of the body. The rash only occurs on parts of the body that were actually exposed to the plant oil. Poison ivy rashes can appear to spread if urushiol oil is trapped under your fingernails and you scratch an itch. While you can't get a rash from coming from your spouse, you can get it from clothing or other items that have the plant oil on them. For example, the clothes your spouse was wearing that came into contact with the poison ivy plant. Poison ivy oil can cling to garden tools or even pet fur. The oil from poison ivy is known to linger. According to the FDA, it can stick around on surfaces, sometimes for years, until it is washed away using water or rubbing alcohol. So be certain that all surfaces that are potentially contaminated are cleaned thoroughly to reduce your risk.

Research we're watching

Cosmetic procedures, including injection of neurotoxins (like Botox) and dermal fillers, have become very popular for their power to smooth wrinkles and minimize signs of aging. But the American Academy of Dermatology is warning that these procedures are not for DIYers. An article published in the April 2020 issue of the Journal of the American Academy of Dermatology outlined an uptick in the number of illegal injectable fillers and neurotoxins being sold to the public online. When used by trained providers, these products are generally safe, but serious complications can arise, including stroke, infections, blindness, and tissue death. In rare cases, improper use leads to fatal complications. Some people have been purchasing these products online and following Internet tutorials to inject the products themselves. If you are planning on having any of these treatments, be certain to have the procedure performed in a medical office by a licensed medical professional.

The benefits of tub baths are more than skin deep. Bathing regularly can help ease pain and potentially benefit your heart.

You know that sinking into a warm bath at the end of a long day can help you relax and unwind, but did you know it might also be good for your health? Research shows that using baths as a form of medical therapy, sometimes referred to as balneotherapy (see "Balneotherapy, or bath therapy"), can bring health benefits — among them, easing certain types of chronic pain, helping your skin, and potentially even improving heart health.
