WebDec 22, 2024 · 1.1 Brief Outline of PDT. Photodynamic therapy (PDT) is photo irradiation-initiated cancer treatment technique by using photo-responsive materials, i.e., photosensitizers [1, 2].Today, various photosensitizes are widely reported for PDT, and these photosensitizers absorb specific wavelength light and it generates reactive oxygen species. WebMay 7, 2024 · The incidence of photo-aging is up to 80–90% in some studies and most common in men (72%) than in women (47%). 9 UVB irradiation induces the production of reactive oxygen species (ROS) and direct DNA damage. ROS induces activation of mitogen-activated protein kinase (MAPK), nuclear factor kB (NF-kB), and activator protein-1 (AP-1).
