This reduces the treatment time, makes the treatment more effective, and enables the use of a weaker psoralen. The physician and physiotherapists can choose a starting dose of UV based on the patient's skin type. The UV dose will be increased in every treatment until the skin starts to respond, normally when it becomes a little bit pink.
To date, there is no link between an increase in a patient's risk of skin cancer and the proper use of narrow-band UVB phototherapy. [1] [2] "Proper use" is generally defined as reaching the "Sub-Erythemic Dose" (S.E.D.), the maximum amount of UVB your skin can receive without burning. Certain fungal growths under the toenail can be treated ...
Ultraviolet radiation is known to suppress the immune system and reduce inflammatory responses. Light therapy for skin conditions like psoriasis usually use 313 nanometer UVB though it may use UVA (315–400 nm wavelength) or a broader spectrum UVB (280–315 nm wavelength). UVA combined with psoralen, a drug taken orally, is known as PUVA ...
While blue light therapy has similar mechanisms for skin enhancement as red light therapy, its usage for photodynamic therapies in treating cancer are slightly different. Blue light therapy stimulates immune system defences, destroys blood vessels that help cancer cells grow, and causes cell death by reacting with oxygen. [ 16 ]
[43] [failed verification] UVC is the highest-energy, most-dangerous type of ultraviolet radiation, and causes adverse effects that can variously be mutagenic or carcinogenic. [44] Despite the importance of the sun to vitamin D synthesis, it is prudent to limit the exposure of skin to UV radiation from sunlight [45] and from tanning beds. [46]
Psoralen plus UVA (PUVA) therapy can be used to treat hyperproliferative skin disorders like psoriasis and certain kinds of skin cancer. [2] Unfortunately, PUVA treatment itself leads to a higher risk of skin cancer. [3] An important use of psoralen is in PUVA treatment for skin problems such as psoriasis and, to a lesser extent, eczema and ...
The location of 'far-UVC' radiation (200-235 nm) in the electromagnetic spectrum. Far-UVC is a type of ultraviolet germicidal irradiation being studied and commercially developed for its combination of pathogen inactivation properties and reduced negative effects on human health when used within exposure guidelines.

Radiation dermatitis, in the form of intense erythema and vesiculation of the skin, may be observed in radiation ports. [3]: 131 As many as 95% of patients treated with radiation therapy for cancer will experience a skin reaction. Some reactions are immediate, while others may be later (e.g., months after treatment).
