Taming the chronic inflammation of psoriasis

Psoriasis is a chronic inflammatory condition in which the immune system attacks the skin. It causes painful skin lesions and may also lead to psoriatic arthritis, hypertension, diabetes, chronic kidney disease, or coronary artery disease. Psoriasis treatments include topical steroids, gentle exfoliant lotions, emollients that keep the skin hydrated, ultraviolet light (phototherapy), laser therapies, vitamin A (retinoid creams), and medications (for moderate-to-severe psoriasis). People with psoriasis are encouraged to get vaccinated against COVID-19 with an mRNA vaccine (from either Pfizer or Moderna) as soon as possible, if they haven’t already done so.

You don't say? Pointing a finger(nail) at your health

Regular, healthy nails are smooth, uniformly shaped, and often with a lighter half-moon shape under the nail near the cuticle. Yet some conditions can show their mark on your fingernails, such as lung disease, psoriasis, and a heart valve infection.

Sunscreen makers withdraw products found to contain cancer-causing substance

Inspect your nails for melanoma

Melanoma doesn’t only affect the skin; it can sometimes occur in and around the nails on the fingers and toes. People should examine the nails as well as the skin for signs of cancer. One sign to look for is dark streaks or bands under the nail.

You don't say? Hair today, gone tomorrow

Can a daily scoop of collagen powder really improve your skin?

Manufacturers tout collagen supplements as a way to improve signs of skin aging and skin quality. There is some research that shows they may bring skin benefits, reducing wrinkles, speeding wound healing, and improving skin hydration and elasticity. But because supplements aren’t regulated, quality may be highly variable. While collagen supplements are believed to be safe, there aren’t any long-term safety studies to date.

Shaking off shingles

Shingles is a painful neurological condition that is more likely to attack as people age. Left untreated, it can increase risk for chronic pain, blindness, and other long-term health problems.

Shedding your skin

Chemical peels can help improve your skin, if you choose the right product and follow safety instructions.

As you age, your skin changes, and not always in a good way. Some of the most common problems are caused by sun damage, including dark spots, rough texture, fine lines, and wrinkles. Chemical peels, which use a chemical solution to remove the top layers of the skin, are billed as one way to target these changes and improve the skin. Peels can be done at home, in a medical spa, or at a dermatologist's office. But the question is, are they really effective or good for your skin?

Dr. Hye Jin "Leah" Chung, assistant professor in the Department of Dermatology at Harvard Medical School, says yes, chemical peels can help your skin. But that endorsement comes with a caveat, she says. "They are beneficial as long as you use the right agent and the right technique," says Dr. Chung. Used incorrectly, chemical peels can be harmful and even cause burns or pigment changes.
