    en.wikipedia.org/wiki/Solar_urticaria

    Solar urticaria (SU) is a rare condition in which exposure to ultraviolet or UV radiation, or sometimes even visible light, induces a case of urticaria or hives that can appear in both covered and uncovered areas of the skin. [1] [2] It is classified as a type of physical urticaria. [3] The classification of disease types is somewhat controversial.

    [45] [failed verification] UVC is the highest-energy, most-dangerous type of ultraviolet radiation, and causes adverse effects that can variously be mutagenic or carcinogenic. [46] Despite the importance of the sun to vitamin D synthesis, it is prudent to limit the exposure of skin to UV radiation from sunlight [47] and from tanning beds. [48]

    en.wikipedia.org/wiki/Photodermatosis

    Photodermatoses is a skin condition resulting in abnormal skin reactions to ultraviolet (UV) radiation. [1] These abnormal skin reactions may develop into rashes. While reactions to UV radiation is common, true photodermatoses is considered when an abnormal reaction is caused by UV-A rays or radiation between 320 and 400 nm.

    Prolonged exposure to ultraviolet radiation from the sun can lead to melanoma and other skin malignancies. [4] Clear evidence establishes ultraviolet radiation, especially the non-ionizing medium wave UVB, as the cause of most non-melanoma skin cancers, which are the most common forms of cancer in the world.

    en.wikipedia.org/wiki/Sunburn

    Excessive UV radiation is the leading cause of (primarily) non-malignant skin tumors, [1] [2] which in extreme cases can be life-threatening. Sunburn is an inflammatory response in the tissue triggered by direct DNA damage by UV radiation. When the cells' DNA is overly damaged by UV radiation, type I cell-death is triggered and the tissue is ...

    Phytophotodermatitis may be aggravated by the additional levels of ultraviolet light emitted by compact fluorescent light. Patients undergoing photodynamic therapy are at additional risk of adverse photosensitive reactions caused by compact fluorescent light. One cause of cataracts is exposure to ultraviolet light. Provided the level of UV ...

    Phytophotodermatitis, also known as berloque dermatitis, [1] [2] [3] margarita photodermatitis, [4] [5] lime disease [6] or lime phytodermatitis [6] is a cutaneous phototoxic inflammatory reaction resulting from contact with a light-sensitizing botanical agent (such as lime juice) followed by exposure to ultraviolet A (UV-A) light (from the sun, for instance).
