What is PUVA? PUVA or photochemotherapy is a type of ultraviolet radiation treatment (phototherapy) used for severe skin diseases. PUVA is a combination treatment which consists of Psoralens (P) and then exposing the skin to UVA (long wave ultraviolet radiation). It has been available in its present form since 1976.
PU is generally an abbreviation for polyurethane, a flexible and resilient material that is foamy or rubbery. The substance is categorised as a polymer and can be manipulated to take on a foam, liquid, or solid form. It is elastic like rubber, but strong, like metal and therefore it can be used to make tires.
