Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

Photochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Development of chalcones structure‐related to avobenzone: Photoprotection, photostability, and safety evaluation

Photochemistry and Photobiology, EarlyView.
Scaffold hopping strategy used to develop chalcones structure‐related to the avobenzone tautomer. Positive aspects of 2‐hydroxychalcones are highlighted. Abstract Chalcones are α,β‐unsaturated ketones with extended π‐conjugation, making them promising scaffolds for the development of organic UV filters.

Sun exposure and photoprotection: Habits, knowledge, and attitudes among elite beach soccer players

Photochemistry and Photobiology, EarlyView.
Elite beach soccer players experience high ultraviolet radiation exposure and frequent sunburn episodes despite widespread sunscreen use. Deficiencies in sunscreen reapplication, shade‐seeking behaviors, and skin surveillance practices were identified. These findings highlight the need for targeted photoprotection interventions in beach sports athletes.

In vitro testing of zinc oxide sunscreens

, 2012
The UVA performances of two all-mineral zinc oxide sunscreens are measured following Colipa and ISO procedures and compared to a sunscreen containing only organic actives. It is found that the two sunscreen types yield very different in vitro SPF and UVA

Revisiting the action spectrum of DNA damage: Chemiexcitation and the expanded biological spectrum of cyclobutane pyrimidine dimer formation

Photochemistry and Photobiology, EarlyView.
UVB and UVA generate cyclobutane pyrimidine dimers (CPDs) during irradiation (purple). After exposure ends, chemiexcitation in pigmented melanocytes continues to generate delayed CPDs (yellow), even as repair removes some pre‐existing lesions. Consequently, total CPD burden can rise while visible erythema fades.
