This study observed that melanoma survivors had higher odds of using sunscreen and seeking shade compared to cancer-free individuals, but their overall adherence to sun protection was less than expected given their elevated risk for new skin cancers.

This study found that in mouse melanocytes, the cytoplasmic dynein complex component Dynlt3 is necessary for proper melanosome transport, acidity regulation, and effective transfer to keratinocytes, linking it to skin pigmentation processes.

This study found that emergency department visits due to sunburn were more prevalent and costly during the summer, with a higher likelihood among lower-income men from the South.

This study found that UVB exposure led to visible tanning and distinct DNA methylation changes in pigmentation genes in tan-capable skin but not in non-tan skin, highlighting GNAS as a potentially UVB-responsive gene.

This study found that UVA blocker-containing sunscreens instantly reduced follicular fluorescence due to porphyrins in facial skin, with the effect lasting for a few hours, influenced by sunscreen amount and formulation.

This study analyzed techniques to create the popular "sun-kissed" hair look on dark-to-medium blonde (Level 5–6) tones, concluding that a 2–3 level differential, targeted placement across three cranial zones, and acidic glossing are essential for optimal results.

This study found that UVA and UVB exposure increased hydroquinone and sunscreen absorption in nude mouse skin, with less absorption enhancement observed in more lipophilic sunscreens.

In this study, UVB irradiation increased mast cell degranulation only when skin was innervated, suggesting that the interaction between mast cells and nerve fibres may exacerbate solar elastosis by promoting dysfunctional dermal elastic fiber accumulation, but further research is needed for confirmation.

This study used a 3D simulation to show that human hair provides varying levels of UV protection depending on head orientation and hair alignment, highlighting hair's role in scalp UV protection, especially for those with alopecia.

This review synthesizes research on solar radiation's multifaceted effects on skin and recent advancements in sunscreen technology, including formulation, testing methods, and the use of AI, to inform future sun protection product development.

This review discusses the chemical effects of UV radiation on hair, hair photoaging, and photoprotective measures, and calls for more focused research in hair photoprotection as a field.

Most sunscreens meet safety standards, but tanning products often don't.

This study found that sunlight exposure causes significant structural and chemical damage to hair, including cuticle loss, cortex damage, and discoloration, with water playing a major role in discoloration of brown hair.

This study observed that phototherapy is an effective and well-tolerated treatment for childhood dermatoses, particularly for psoriasis and pityriasis lichenoides chronica.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

This case report describes an 18-month-old boy who developed a rare phototoxic skin reaction to terbinafine, likely triggered by sunlight exposure, which resolved after treatment with corticosteroid cream and sun avoidance.

This study found that facial sun damage scores from UV photography correlate with skin cancer and melanoma risk factors, suggesting this technology may help identify individuals at higher risk.

This review explores the detrimental effects of sunlight on the skin’s circadian rhythm and photodamage, noting the potential of natural cosmeceuticals to influence this rhythm, but reports no new results.

This study developed an inexpensive method to provide initial data on both the photostability and toxicity of pure active principles and their photodegradation products.

In this study, patients with frontal fibrosing alopecia showed more actinic damage than control subjects, suggesting sunscreen use by these patients may be a consequence rather than a cause of the condition.

This study reported that regular mole examinations and UVR protection are crucial for skin cancer prevention, particularly for individuals with fair skin, inflammatory skin conditions, diabetes, and those on photosensitizing medications.

This article highlights the limited photoprotection baseball caps provide against UV radiation and recommends additional sun protection measures, especially for those at risk of androgenetic alopecia, but reports no new results.

This study found that topical alpha-terthienyl combined with UVA radiation rapidly induced dose-dependent cutaneous photosensitization in guinea pigs, suggesting potential for photochemotherapy in skin disorders without future carcinogenic risks.

This review discusses the effects of sunlight and artificial UV radiation on the skin and reports no new clinical results; a panel from the NIH found the evidence insufficient to recommend tretinoin for sun-induced wrinkles.

Sun-protective behaviors increased, and sunburns decreased in both Hispanic and Non-Hispanic White individuals from 2005 to 2020.

This study found that UV radiation exposure during a simulated Brazilian summer caused more significant mechanical damage to natural hair than bleaching, although both caused comparable structural alterations, with double bleaching leading to the most severe protein degradation.

In this study using SKH-1 mice, researchers observed that acute UVB exposure increased expression of retinoid metabolism proteins and decreased retinol storage enzyme levels, suggesting enhanced retinoic acid synthesis in the epidermis.
