This study found that a polyherbal sunscreen cream, F4, containing Camellia sinensis, Vitis vinifera, and Silybum marianum extracts demonstrated strong antioxidant and photoprotective properties, similar to synthetic sunscreens.

This study found that many childhood cancer survivors at one institution delayed dermatologic care and had inadequate sun protection, risking late diagnosis of skin complications from cancer therapy.

This study found that a sunscreen with oxothiazolidine and δ-tocopheryl glucoside provided complementary oxidative protection, with immediate but brief effects from oxothiazolidine and prolonged effects from the slower-absorbing δ-tocopheryl glucoside.

This study investigated single-cell changes in photoaged skin, revealing distinct cell clusters and increased activity in PD-L1 and PD-1 pathways in sun-exposed areas, enhancing understanding of UVA-induced skin damage and potential prevention targets for photoaging and UV-induced skin cancers.

This study introduces the "skinspan" framework to promote skin longevity through sun protection, topical retinoids, and antioxidants as first-line care. It suggests lasers and emerging therapies as additional options but emphasizes the need for more randomized controlled trials to solidify the evidence base.

This study demonstrates that extracellular ATP induced by UV radiation promotes melanin production in human melanocytes, suggesting ATP-induced purinergic signaling may influence skin pigmentation.

This study found that acute UVB exposure in mice increases the synthesis of retinoic acid in the epidermis, which is necessary for normal repair from UVB light.

This article discusses how the balding scalp's exposure to UV and near-infrared light may accelerate aging, with changes detectable under ultraviolet light; it presents no new clinical findings.

In this study, researchers found that while sunscreens added to hair products do not provide expected protection, the dark hair absorbs the most radiation across all wavelengths, indicating a need for enhanced protection.

This study found that sinapic acid demonstrated antioxidant and anti-inflammatory effects against UVB-induced damage in human keratinocytes, suggesting its potential as an anti-aging cosmetic ingredient.

This article reviews evidence suggesting that vitamin D and its metabolite may help protect against nonmelanoma skin cancer, but reports no new empirical findings.

This study found that balneophototherapy improved skin lesions in a 13-year-old with severe ichthyosis linearis circumflexa, but regular treatment is likely necessary to maintain remission.

This study reports cases of androgenetic alopecia patients with depigmented macules on sun-exposed scalp areas, suggesting potential ultraviolet-induced scalp leukoderma not covered in existing dermatology texts.

This review explores the mechanisms by which UV radiation causes skin cancer, highlighting UV-induced DNA damage and its implications for cancer prevention strategies, but reports no new findings.

This review summarizes preliminary evidence suggesting that CBD-containing sunscreen may offer UV protection through antioxidant properties, though further studies are needed to confirm safety and efficacy.

This study synthesized a new organic sunscreen with broad photoprotective properties and demonstrated it to be non-toxic. The resultant cream, containing nanostructured lipid carriers, showed suitable application qualities and achieved a satisfactory SPF value of 16.

This review discusses the mechanisms by which sunlight exposure aggravates hair aging and highlights the role of hair pigments in providing photochemical protection, reporting no new results.

This study in transgenic mice found that the combination of SPF 15 sunscreen and a UVA filter provided strong protection against UVA-induced elastin promoter activation and thus may reduce photoaging.

As skin ages, it gets thinner, paler, and more wrinkled, and protection and care like sunblock and moisturizers are important.

This study noted that combining oral acitretin with narrowband ultraviolet B therapy may reduce treatment time and dosages for psoriasis, potentially lowering the long-term skin cancer risk.

Most clinicians follow discharge guidelines, many lupus patients don't use sunscreen regularly, dithranol is effective for psoriasis, biopsy methods should be based on lesion type, voriconazole may raise skin cancer risk, a new scale can help diagnose female hair loss early, and most melanomas may develop from existing moles.

This review discusses various topics from the 62nd Annual Montagna Symposium on the Biology of Skin, focusing on the diverse effects of light on skin biology, and reports no new clinical results.

This study found that low-dose topical alpha-terthienyl combined with UVA radiation can induce cutaneous photosensitization in guinea pigs, suggesting a possible photochemotherapy approach for skin diseases like psoriasis.

This review found that solar radiation, pollution, and trace metals cause significant damage to human hair, with factors like UVB radiation primarily affecting light-colored and bleached hair; most data were derived from in vitro and ex vivo simulations.

This study found that UV exposure in human skin induces IL-10 production by macrophages, while Langerhans cells are depleted and their IL-12 production is downregulated.

This study observed significant skin changes, including epidermal thickening and pleomorphic keratinocytes, in rats after subchronic UVB irradiation, highlighting specific reactions in the dorsal skin.

Cellulite may be linked to low adiponectin, isotretinoin with UVB can treat psoriasis effectively, permanent alopecia post-chemotherapy resembles a unique hair loss, deodorants may cause fragrance allergies, desmoplastic melanoma is becoming more common, and intensive UVB treatment can give long-term psoriasis remission.

This study reported that sunscreen with SPF50+ provides a high level of DNA protection against UV-induced damage in a reconstituted human epidermis model, comparable to that in skin explants.

Bald men should protect their scalps from the sun to reduce skin cancer risk.
