This review compiles epidemiological data on actinic keratoses and suggests promoting strategies like early diagnosis and photoprotection to prevent progression to skin cancer, but it reports no new clinical findings.

This study found that cis-urocanic acid can engage in non-enzymatic reactions with reactive sulphur species, forming new metabolites, and suggests sulphide donors may protect against UVB-related toxicity.

Adequate vitamin D is crucial for skin health and should be considered in dermatology.

Clear glass lets most UV rays through, so it's important to know how well different glasses block UV to protect yourself.

The researchers found that SPF50+ sunscreens provided the highest DNA protection against solar-simulated radiation in a reconstituted human epidermis model, with formulation type not affecting efficacy for a given SPF.

This study found that high frequency use of sunscreen is associated with frontal fibrosing alopecia among women attending a specialist hair clinic in Australia.

A man developed a rare skin condition and drug-induced lupus, highlighting the need for biopsy in diagnosing skin issues caused by sunlight.

This manuscript suggests that exogenous hydrogen peroxide is a primary risk factor for higher incidence of cutaneous melanoma in swimmers, with UV radiation playing a secondary role.

Sunscreen use may increase the risk of frontal fibrosing alopecia.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.

This study analyzed NHANES data from 2005 to 2020 and found that sunscreen-wearing behavior was more common among females than males, individuals aged 29-56 compared to those aged 0-28, and significantly less likely among non-Hispanic Black respondents compared to non-Hispanic White respondents.

This commentary highlights the importance of additional sun protection for individuals with alopecia, noting that common headwear like baseball caps may provide insufficient photoprotection for the scalp.

This study compiles data on the microstructural and cytotoxic properties of nano physical sunscreens, emphasizing the need for a technology platform to assess nanomaterial characteristics due to their growing use in cosmetics.

This review compiles existing research on infrared radiation's effects on human skin, noting both its potential harmful thermal impacts and encouraging therapeutic applications, but reports no new clinical results.

This study found variation in erythema induction across skin types, suggesting different SSR dose responses and highlighting a potential model for tailoring anti-inflammatory treatments.

This study investigated the use of spironolactone in patients with estrogen-dependent cancers, aiming to determine if it is linked to increased cancer recurrence risk, but results are not reported.

This report describes cases of increased hair loss and scalp sunburns in patients using 3% minoxidil and 0.01% tretinoin, suggesting caution with tretinoin use on sunny days.

In this study, compliance with UV protection recommendations was highest among vitiligo patients compared to those with other cutaneous immune-mediated inflammatory dermatoses, indicating a need for tailored education to improve compliance across all groups.

This study found that higher melanin concentration in black hair offers photoprotection against sunlight-induced protein damage in the cortex, whereas the cuticle experiences similar photodamage regardless of hair pigmentation.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

This study found that ultraviolet A rays damage all hair types, with stronger adverse effects on colored and permanently waved hair, suggesting the use of sunblock products for hair protection.

In this study, a combined regimen of an oral supplement with Pinus pinaster, Grape seed extract, vitamins, and minerals, plus high SPF sunscreen, significantly improved mild-to-moderate facial melasma in 30 women over 84 days, reducing pigmentation and enhancing cosmetic appearance with no reported adverse effects.

This study found that a single high dose of oral vitamin D reduced UV-induced skin erythema and inflammation in humans by enhancing autophagy, suggesting new clinical avenues for skin repair.

UV radiation may cause DNA changes in skin, certain UVB therapy helps psoriasis, a new gene mutation is linked to mild piebaldism, different immune cells affect psoriasis, a drug promotes hair growth, and some cancer drugs could treat skin barrier issues.

The researchers reported that hair offers a measurable protective barrier against UVB and UVA radiation, which increases with hair density, thickness, and melanin content, suggesting a role in skin cancer prevention.

This review discusses the genetic and environmental factors involved in the development of skin cancers like squamous cell carcinoma, basal cell carcinoma, and melanoma, but does not report new clinical findings.

This study found that short-term NB-UVB treatment significantly reduced anxiety levels in psoriasis patients, but not depression.

This study found that sulforaphane-rich broccoli sprout extracts reduced UV-induced erythema by 37.7% in humans, suggesting a protective strategy against UVR damage.

This study found that the circadian clock in mouse skin regulates cell proliferation and affects sensitivity to UVB-induced DNA damage, with potential implications for understanding human skin cancer risk.
