Voriconazole is used in antifungal prophylaxis. We performed a retrospective review of immunocompromised children receiving prophylaxis with voriconazole during major hospital renovation, who developed phototoxic skin reactions. The overall incidence of phototoxic skin reactions was 33%. A voriconazole dose of ≥6 mg/kg of body weight per dose twice daily was associated with a significantly greater risk to develop phototoxic skin reactions compared with lower doses.

Phototoxicity of skin due to the application of skincare products or fragrances is increasing from day to day, since a lot of natural extracts, with low or no toxicity in the dark, are being used in the skin exposed to solar radiation. In particular, the use of 4-hydroxy-3-methoxy benzaldehyde, known as vanillin, in the pharmaceutical, food, and cosmetic industries has increased in the last years. This compound is generally considered as safe for humans, and it has been used in a wide range of applications.

Article Synopsis
- Phototoxicity, a common issue linked to many medications including over-the-counter ones, highlights the importance of testing drugs for their potential to cause harm under UV light!
- This study focuses on the effects of ketoprofen on human skin cells, using various tests to analyze its cytotoxicity and phototoxicity under different treatment conditions!
- Findings revealed that ketoprofen poses the highest risk of phototoxic reactions when it is directly applied to cells during UV exposure, affecting both pigmented and non-pigmented skin cells!

Background: Photodynamic Therapy (PDT) is a therapeutic modality that combines the application of a photoactive compound (photosensitizer, PS) with low-power light to generate reactive oxygen species in the target tissue, resulting in cytotoxic damage and cell death, while sparing adjacent tissues. The objective of this study was to evaluate the phototoxicity of a cyanine dye with two chromophores (biscyanines, BCD) in systems with varying levels of cellular organization, and we used the Photogem® (a photosensitizer approved by the Brazilian ANVISA agency for clinical use in Photodynamic Therapy) as a positive control.
Materials And Methods: The cytotoxicity of the compounds was assessed in vitro in 2D monolayers, 3D spheroid cultures, and artificial skin models.

Topical sunscreens decrease the quantity of ultraviolet (UV) light from the sun reaching the skin by either blocking or scattering it and help protect the skin from dyspigmentation, photoaging, DNA damage, and photocarcinogenesis, especially in photosensitive individuals. The significant role played by visible light and infrared light in skin pigmentation and photoaging has been recognized in recent years. The majority of broad-spectrum sunscreens protect against UV-B (290-320nm) and UV-A (320-400nm) radiation.

Chemical phototoxicity is elicited after exposure of skin to photosensitive chemicals, followed by exposure to sunlight. The intensity of ultraviolet light has increased due to ozone layer destruction; therefore, interest in avoidance of the phototoxicity risk of chemicals has increased in drug discovery and product development. Based on the mechanism of chemical phototoxicity, a photosafety screening strategy focusing on the photoreactivity of chemicals and skin exposure to chemicals was proposed.
