Daylight photodynamic therapy: the Southern California experience.

Background: Photodynamic therapy (PDT) is a safe and effective treatment for actinic keratoses (AKs) and photoactinic damage. Three elements are needed for PDT: a photosensitizer, oxygen, and a light source. Conventional PDT is performed with a variety of different laser and light sources including blue, yellow and red in addition to filtered intense pulsed lights (IPL).

A comparison of two 810 diode lasers for hair removal: low fluence, multiple pass versus a high fluence, single pass technique.

Background & Objective: Laser hair removal has become an increasingly popular method to remove unwanted or excessive hair. We have assessed the relative efficacy and discomfort associated with competing hair removal techniques, namely a high average power 810 nm diode laser using an “in-motion” technique with a market-leading 810 nm device with a single-pass vacuum-assisted technique. This study has determined the long-term (6-12 months) hair reduction efficacy and the relative pain induction intensities of these devices.
