Microneedling Can Help Surgical Scars Fade, Especially If Done Early
A technique called microneedling may help surgical scars heal more attractively — especially if it's done within a couple of months of surgery, a small study suggests. Researchers found that for 25 patients, microneedling improved the long-term appearance of scars after various types of surgery — based on both patient and doctor ratings. But the sooner it was done, the better. Patients who underwent their first microneedling session within six or seven weeks of surgery had the best results. That, the researchers said, goes against the "conventional wisdom," which holds that microneedling should be delayed until scars are about a year old.Source: U.S. News
Yale dermatologist seeing skin cancer in younger people
Skin cancer is the most common form of cancer and it is completely preventable. With the Memorial Day weekend almost here and a nice forecast ahead, Yale Medicine Dermatologist Kathleen Suozzi warns people to protect their skin. She does not like a trend she is now treating. “I have patients, I’m seeing patients in their twenties, in their thirties developing skin cancer and this is alarming because we know that once you develop a skin cancer you’re at increased risk for all additional skin cancers,” Suozzi said. Suozzi said to pay attention to what the UV index is if you plan to spend time outdoors. It is the strength of the sunburn-producing ultraviolet radiation. Numbers 8 through 10 mean it is high. She said mid-summer is not the only time when sun danger is high. “In general, the UV indexes we will see around this area will peak around mid-summer, so late July, early August but certainly on spring days we can see higher UV indexes that are looking more like our summer levels.”Source: News 8
Overview Itchy skin is a something we’ve all experienced from time to time, whether from an uncomfortable woolen sweater, seasonal dry skin or, perhaps, as a reaction to certain detergents or personal care products. Sometimes, when an itch lasts long enough—and is severe—it can lead to a condition called prurigo nodularis. A hallmark of prurigo nodularis is the development of firm bumps (called nodules) that intensify the itchiness. People with prurigo nodularis report itching that is so intense it disrupts sleep and prompts so much scratching that the skin begins to bleed. Prurigo nodularis can affect people of any age, though is most common among those in middle age or older. “Prurigo nodularis can be an extremely debilitating condition characterized by a relentless itch,” says Yale Medicine.

How to treat male pattern baldness and why you might be more susceptible than most
A receding hairline or thinning hair on the top of the head is a sign of male pattern baldness.Chalffy/Getty Images Male pattern baldness is inevitable for some and can start early before you even turn 21.

Visit Insider's Health Reference library for more advice. Male pattern baldness — or androgenetic alopecia — accounts for more than 95% of hair loss in men, making it the most common type of hair loss. About 25% of men who suffer from it will start losing hair before the age of 21. The condition is not harmful to your health, and treatment is unnecessary if you are content with your appearance. Moreover, there's no way to prevent hair loss, but some medicines can slow it down. Here's what you need to know about the causes, symptoms, and treatment for male pattern baldness.Source: Business Insider
How much sunlight you really need to get enough vitamin D
The sun is our most common source of vitamin D since it's rarely found in foods. In fact, when exposed to ultraviolet B (UVB) rays, our skin produces vitamin D naturally. Yet, about 35% of adults in America have a vitamin D deficiency. Important: Adults need about 15 micrograms of vitamin D daily to meet nutrient requirements. And that's a problem since vitamin D is important for strengthening and maintaining bones, supporting a healthy immune system, and breaking down glucose in the body, says David J. Leffell, MD, chief of Yale Medicine Dermatologic Surgery and professor of dermatology at Yale School of Medicine. Here's how to make sure you're getting enough of it from the sun.Source: Insider
How to differentiate harmless sunspots from skin cancer
Sunspots are flat, dark spots that appear on parts of your skin that you frequently expose to the sun, such as your face, hands, arms, shoulders, and feet. While anyone can develop these spots, they are particularly common in people with light skin over the age of 40, especially those who spend a lot of time in the sun. Genetics also play a role, so having a family history of sunspots can make you more likely to get them. Note: Sunspots are also known as age spots, solar lentigines, and liver spots although they don't have anything to do with liver function. Sunspots are permanent marks that are harmless, so you don't need to remove them for health reasons. However, if you don't like their appearance, there are steps you can take to lighten them. Here are some tips on how to prevent sunspots and reduce their appearance, as well as how to differentiate a sunspot from something more serious like skin cancer.Source: Insider
Yale dermatologist weighs in on J&J sunscreen recalls, preferred types to protect skin
The FDA realizes that sunscreen use is critical to public health, saying melanoma continues to be on the rise, with most cases caused by excessive sun exposure. Johnson and Johnson recently announced a voluntary recall of five spray sunscreen products under the Neutrogena and Aveeno brands. RELATED: Johnson & Johnson recalling sunscreens due to traces of benzene, cancer-causing chemical The affected products, packaged in aerosol cans, are Aveeno Protect + Refresh aerosol sunscreen, and four Neutrogena sunscreen versions: Beach Defense aerosol sunscreen, CoolDry Sport aerosol sunscreen, Invisible Daily Defense aerosol sunscreen, and UltraSheer aerosol sunscreen. Research by New Haven-based Valisure evaluated sunscreens and after sun products, revealing varying levels of the carcinogen benzene in some.

Hell's itch is a rare sunburn reaction that feels like 'fire ants under the skin'
Ultraviolet (UV) rays can cause plenty of skin damage and pain if proper precautions aren't taken. As if a painful sunburn isn't bad enough, in rare occasions, it can escalate. This phenomenon is referred to as "hell's itch". What is hell's itch? Hell's itch is a rare, extremely uncomfortable response to a sunburn, says dermatologist David J. Leffell, MD, section chief of the Dermatologic Surgery and Cutaneous Oncology Programs at Yale Medicine. It will typically crop up two days after a severe sunburn has occurred, and will last for two or more days. "It is described as a maddening, uncontrollable itch of the affected skin. Some have described it as deep sandpaper rubbing on the skin or severe pins and needles," says Leffell. The scientific literature has minimal information on the phenomenon of hell's itch. One of the only mentions of it in medical journals is a firsthand account by a medical student that was published in 2018 in the Journal of Travel Medicine.Source: Insider
Psoriasis on the Knees and Elbows: What It Looks Like, How to Treat It
She’s been mortified by these flares since childhood. “As a kid, I’d go to day camp wearing jeans and long-sleeved shirts — and I never, ever wore a bathing suit,” she recalls. The knees and elbows are the most common location for psoriasis flare-ups. “Those are the textbook cases,” says Elisabeth Richard, MD, an assistant professor of dermatology at the Johns Hopkins University School of Medicine in Baltimore. Psoriasis on these body parts tends to have a distinctive appearance: “You’ll usually see a well-circumscribed plaque, bigger than a centimeter, with thickened skin and overlying white scales,” Dr. Richard explains. Plaques may appear red or salmon pink on white skin and purple or brown on Black or brown skin. Psoriasis most often appears on the front of the knees and the elbows, known as extensor surfaces, says Jeffrey Cohen, MD, an assistant professor of dermatology and director of the psoriasis treatment program at Yale Medical School in New Haven, Connecticut.Source: Everyday Health

A Strange Rash Had Doctors Stumped. Was It an Insect Bite?
The 73-year-old man looked up at the clear summer sky — the morning was nearly gone. He had finished mowing the main part of his lawn and was trimming the edges near the shrubbery with the weed wacker. He wanted to finish before the sun and heat made the work too hard. Suddenly he felt a sharp sting on the lower part of his shin. He glanced down at his bare leg. Nothing there. He still had the hedges to trim, so he kept working. He quickly finished the needed pruning, then moved on to the inside tasks he had planned.Source: The New York Times Magazine
