The study shows "how a feeling, such as psychological stress, can translate into a biological event, namely inflamed skin", says co-author Shenbin Liu, a neurobiologist at Fudan University in Shanghai, China.

When pop sensation Sabrina Carpenter shared a TikTok video talking about her favourite lip balm, she described how it absorbs the lips' natural pH and "brings out this beautiful pink" and keeps them "super moisturised." The product went viral, as did the concept of pH-reactive make-up.

Psoriasis is an inflammatory skin problem that usually shows up as dry, itchy, scaly patches of skin (plaques and erythematous papules covered with silvery scales). The condition usually develops when the life cycle of the skin cells speeds up. Consequently, skin cells build up rapidly on the skin's surface and form scales and red patches that are usually painful and itchy.

Rare Disease Day, on 28 February, highlights the more than 6,100 conditions identified worldwide, including xeroderma pigmentosum (XP), a rare genetic disorder that affects just over 100 people in France. Those affected are often referred to as Children of the Moon, a name that reflects their extreme sensitivity to ultraviolet light.

Psoriasis is an autoimmune disease. When the immune system malfunctions, it causes the skin cells to regenerate faster than normal. This results in rapid cell turnover and a red, scaly rash that covers the skin and can affect all parts of the body, even the fingernails.

I caught myself doing it again last week-meticulously applying sunscreen to my face while completely ignoring my neck. It wasn't until I saw a photo from my friend's wedding that I noticed the difference. My face looked smooth and even-toned, but my neck? Let's just say it was telling a different story. The fine lines and slight sagging made me realize I'd been treating my neck like it was somehow immune to aging. Turns out, I've had it backward this whole time.

Clothes, toothbrushes, hairbrushes, a teddy Although it should be two teddies, she re-evaluates, quickly. I can hear her trying to quell her panic. A diehard survivalist preparing for catastrophe? Actually, a beleaguered 44-year-old mother recovering from scabies an itchy rash caused by microscopic mites that burrow under human skin. Far-fetched as it sounds, emergency evacuation is exactly what she, her partner and children (six and four) resorted to in November in a desperate bid to beat the bugs.

Tanning bed use is tied to almost a threefold increase in melanoma risk, and for the first time, scientists have shown how these devices cause melanoma-linked DNA damage across nearly the entire skin surface, reports a new study published in Science Advances and led by Northwestern Medicine and University of California, San Francisco. Melanoma, the deadliest skin cancer, kills about 11,000 in the U.S. each year. Despite decades of warnings, the precise biological mechanism behind tanning beds' cancer risk remained unclear.

The conventional approach to evaluating the impact of air pollution is to focus on a single exposure during a fixed period of time. But evidence suggests that contaminants work together, magnifying the damage to people's lungs. Conventional studies fail to probe synergistic effects. They also ignore the cumulative effects of lifelong exposures to pollutants, known as the exposome. Researchers need to shift away from single-pollutant studies and towards those involving a broad range of exposures.
