Abstract
A high energy filament lamp light source, such as a quartz tungsten halogen lamp, operated in a pulsed mode with a high voltage input, creates a particular energy output. Applications of such apparatus and methods include treatment of the dermis and/or sub-epidermal tissues for the purpose of skin recontouring, thermal destruction of hair follicles for the purpose of hair removal, and others, and a method which selectively preheats a subsurface region in targeted tissue to sub-thermal modification threshold values without significant heat damage to surrounding layers prior to further treatment.
