The mutagenic and carcinogenic properties of sunlight have been attributed to the short-wavelength range (UVB, 290–320 nm) of the solar UV spectrum. Despite being well established that UVA (320–400 nm) can also damage DNA and that it has mutagenic and carcinogenic properties (Stary and Saras...
Sunlight-induced immunosuppression in humans is initially because of UVB,then UVA,followed by interactive effects[J].Journal of Investigative Dermatology,2005.840-846.doi:10.1111/j.0022-202X.2005.23894.x.Poon TS,bametson RS,Halliday GM. Sunlight-induced immunpsuppression in humans is initaially ...
UV radiation consists of three major types based on their wavelengths: UVA (320–400 nm), UVB (280–320 nm), and UVC (200–280 nm) [4,5]. The UVC fraction is the most mutagenic and lethal, but it is blocked by the atmospheric ozone layer, while UVA has the least mutagenic and ...
The basal layer in human squamous tumors harbors more UVA than UVB fingerprint mutations: A role for UVA in human skin carcinogenesis We hypothesized that a substantial portion of the mutagenic alterations produced in the basal layer of human skin by sunlight are induced by wavelengths in... NS...
However, it needs to be emphasized that UVA is suspected to play a proportionately larger role in photoageing because of its greater abundance in sunlight54. Future studies exploring the influence of UVA on the ECM composition might contribute to the further understanding of the aging process. In...

One of the most important extrinsic aging factors is sunlight, particularly exposure to UVB irradiation, which causes skin photoaging. It has been well known that chronic exposure of human skin to UVB radiation results in photoaging and induces the production of matrix metalloproteinases (MMPs) (Ho...
It is assumed that an hour of human exposure to sunlight corresponds to approximately 30 mJ/cm2 of UVB. Therefore, it is necessary to perform additional analyses based on higher doses of UVB exposure. Furthermore, to confirm or deny the conclusion presented in this study, that induced ROS ...
