When particles are so small that they seep right through skin

Researchers have found that nanoparticles can pass through human skin, especially when damaged, raising concerns about their safety. The study, led by Dr. Lisa DeLouise, used mice as a model and showed that nanoparticles accumulate in skin folds and around hair follicles.

Promising approach to a more effective sunscreen

Researchers discovered a promising new agent, CP-31398, that restores mutant p53 tumor suppressor function and inhibits skin cancer growth in mice exposed to UVB light. The findings suggest potential for this approach as a sunscreen component for preventing and treating UV light-induced skin cancers.

Less sun better than using sunscreen

A comprehensive review suggests that wearing protective clothing is a more effective way to prevent skin cancer and sun damage than relying on sunscreen. The review highlights the characteristics of clothing that can provide optimal protection, including tightly woven fabrics like denim and wool.

Most beachgoers accurately report their sun habits

A recent study found that most adult beachgoers accurately reported their sun habits, with moderate to substantial agreement between self-report measures and objective procedures. The study used a novel sunscreen-swabbing procedure in real-world conditions, providing valuable insights into the validity of self-report sun habits.

Safer suntans through science

Scientists at the University of Kentucky are testing a lotion that stimulates melanin production, reducing UV damage and increasing skin protection. The treatment has promising results, offering an alternative to traditional sunless tanning products and tanning beds.

Sunscreens can damage skin, researchers find

Researchers from UCR report that unless people reapply sunscreen often, filters in sunscreens can generate compounds that attack skin cells, leading to oxidative damage. To reduce ROS levels, more advanced sunscreens with UV-filters on the skin surface are needed or mixing with antioxidants.

Guilt and fear motivate better than hope

A study published in the Journal of Consumer Research suggests that emotions like guilt and regret play a critical role in motivating people to make wise decisions about self-protection. The research finds that appeals combining fear and accountability are more effective than those relying on hope or good intentions.

SPF may not be enough to protect against skin cancer

Researchers tested various sunscreens and methods on volunteers from multiple countries to establish a standard method for determining IPF. However, the study found that high SPF sunscreens may not provide sufficient protection against immunosuppression, potentially increasing skin cancer risk.

Young athletes ignore skin cancer risk

A recent study by Dr. Brian Adams found that 85% of NCAA soccer players and cross-country runners did not use sunscreen during practice, despite being at high risk for sun-related skin cancer. The American Cancer Society estimates that most cases of nonmelanoma skin cancer diagnosed yearly in the US are sun-related.
