A new study led by UC Davis Health System dermatologist April Armstrong found that daily text messages reminding people to apply sunscreen increased its use by nearly twice as much as those who did not receive such messages. The study aimed to explore the potential of text messaging to encourage healthy habits in patients, and its find...
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.
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.
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.
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.
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.
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.
Researchers found that promotion-focused individuals prioritize their ability to follow through with healthy behaviors, while prevention-focused individuals prioritize the effectiveness of the behavior itself. This study has important implications for distributing information about healthy practices.
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.
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.
A randomized controlled trial found that high-protection sunscreen did not influence the duration of sunbathing. In fact, the study discovered that people tend to self-regulate their sun protection with sunscreens by adapting the amount of sunscreen used based on its SPF level.
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.
Patients with a personal or family history of melanoma exhibit similar sunbathing patterns and protective measures to low-risk populations, highlighting the need for improved education and awareness campaigns.
A study found that sun protection habits decreased in children between their first and second summers, with a 32% increase in skin damage. The decrease was attributed to lack of full protection, rather than increased sun exposure, highlighting the need for sustained sun protection efforts.
Researchers at Newcastle University are developing a new type of sunscreen that protects against sun-induced DNA damage, a major cause of skin cancer and ageing. The company, DNAcare Systems, aims to introduce a DNA rating for all sunscreens to reduce skin cancer cases.
A Stanford study found that a sting-inhibiting cream reduced swelling and discomfort after exposure to jellyfish tentacles. The cream works by repelling water, disrupting communication systems, and mimicking a substance found in the jellyfish bell.
The American College of Physicians released guidelines for treating atrial fibrillation, an abnormal heart rhythm that can lead to stroke if uncontrolled. Researchers also reviewed 18 studies on melanoma and sunscreen use, finding no link between the two conditions.
Researchers found physicians and patients were equally likely to use sun protection when going outside for an hour or more. However, the specific forms of sun protection used differed, with physicians using sunscreen more frequently but less often staying in the shade or wearing protective clothing.
Self-tanners contain dihydroxyacetone (DHA), which interacts with skin proteins to create a brown glow. Newer sunscreens offer greater protection against both UVA and UVB radiation, including those developed by Craig Bonda, who found that adding DEHN to avobenzone extends its effectiveness.
A commonly used sunscreen ingredient, PBSA, can damage DNA when exposed to sunlight, according to a recent study. The research suggests that this could lead to increased risk of developing skin cancer if similar damage occurs within skin cells.
