Scientists have developed a fully transparent skin sensor that accurately measures UV radiation, detecting light and converting it to electrical signals. So before the sun's rays reach damaging levels, a phone alert lets users know it's time to cover up.

Not all scar moisturizers are created equal. A new study shows that some of the cheapest, most basic creams outperform expensive, heavily marketed products, with one budget option topping the list for moisture retention and barrier repair.

Psoriasis may not have a cure, but significant relief might be found at the dinner table. A clinical trial has shown that the Mediterranean diet could dramatically improve symptoms, quality of life and overall health of those with the condition.

An inexpensive, over-the-counter form of vitamin B3 cut new skin cancers by an average of 14% in a study of more than 33,000 people. Among those who began taking a daily dose after a first diagnosis, the risk of a repeat skin cancer fell by up to 54%.

Minerals like titanium dioxide are effective sunscreen ingredients, but they can harm coral reefs if used in their non-nanoparticle form. An experimental new sunscreen forgoes the minerals altogether, replacing them with "just-as-effective" pollen.

Nobody likes having blood samples taken, which is why it's always good to hear about possible alternatives. One of the latest takes the form of a self-powered skin patch that painlessly gathers biomarker chemicals for up to 24 hours at a time.

From vampire legends to lab-grown tissue, the idea that young blood can reverse aging is no longer pure myth. A new study shows that proteins secreted by bone marrow cells, triggered by young blood, can rejuvenate aging skin in the lab.

Why do wrinkles form as we age? A new study has revealed that aging skin stretches more sideways under tension, causing it to buckle – like Silly Putty – into deeper, straighter wrinkles. And it all starts with how collagen is arranged.

When the skin is injured, a stem cell’s survival instincts kick in. New research reveals that a simple amino acid, serine, helps push stem cells to abandon hair growth in favor of wound healing, opening the door to new therapies for chronic wounds.

A massive global study has ranked the best and safest treatments for chronic hives when antihistamines fall short. The findings provide a clear treatment roadmap for both patients and clinicians alike.

Vitamin C has been found to rejuvenate aging skin by reactivating genes that drive cell growth, restoring thinning or damaged skin. This discovery presents a new way to improve skin's appearance by going deep below the surface of it.

A study has described how certain bacteria living on our skin can act as microbial sunscreen, protecting us from harmful UV rays. These microbes neutralize UV-induced immune changes, offering a natural defense against the damaging effects of sunlight.
