The intense pulsed light (IPL) and laser technologies are widely used for skin rejuvenation and for treating several dermatological disorders such as skin dyschromia and acne, and for non-ablative dermal remodeling of rhytides and hypertrophic scars. Technological evolution is rapid. The High Power Pulsed Light™ [HPPL™] and Incoherent Fast Light™ technologies [IFL™, Novavision Group S.p.A., 208...

Intense pulsed light (IPL) therapy using noncoherent broad-spectrum light has been reported to be effective for hair removal, and also for treating superficial pigmented lesions like ephelides and solar lentigines. We report complete regression of a pigmented melanocytic nevus, histologically confirmed, after hair removal treatment with IPL. The use of lasers and IPL is a common procedure used ...

The propensity of molecules to spatially align along the polarization vector of intense, pulsed light fields is related to readily-accessible parameters (molecular polarizabilities, moment of inertia, peak intensity of the light and its pulse duration). Predictions can now be made of which molecules can be spatially aligned, and under what circumstances, upon irradiation by intense light. Accou...
