10 lip 2024 · With the knowledge of skin absorption growing in importance for various fields, the need for a database comprised of chemicals and their dermal absorption parameters, such as permeability and ...
Sarah Gilpin. PMID: 25204211. DOI: 10.1515/reveh-2014-0056. Abstract. Dermal exposure is an important route of entry for chemicals in occupational and consumer settings. Key to this exposure is the penetration of the skin's barrier, and key to this penetration is a chemical's vapor pressure.
The impacts of visible light on skin health, including the induction/exacerbation of hyperpigmentation and melanogenesis, are summarized. The role of endogenous and novel exogenous antioxidants and oxygen radical scavengers aimed at reducing the effects of visible light damage to skin health are highlighted.

1 lut 2016 · In the last decade, it has been proposed that the sun's IR-A wavelengths might be deleterious to human skin and that sunscreens, in addition to their desired effect to protect against UV-B and UV-A, should also protect against IR-A (and perhaps even visible light).
Infrared light (760 nm-1 mm) constitutes approximately 40% of the solar radiation reaching the ground at sea level. Shortest wavelength near-infrared (NIR) photons (NIR or IR-A: 760-1,400 nm) can penetrate the epidermis, dermis, and subcutaneous tissue with numerous biological effects.
Detrimental effects such as thermal burns, photocarcinogenesis, and photoaging have been reported, though evidence suggests that these may be due to the thermal effects produced secondary to IR exposure rather than the isolated effect of IR.
