Intense pulsed light Systems release precisely controlled strong pulses of filtered light that are absorbed by the melanin in freckles, sun spots or liver spots. The pigmented area absorbs the light and is heated, and is removed by skin renewal. Following treatment, the pigmented area turns darker and may crust. Over the following weeks the pigmented area will gradually flake away from the skin.
Large, dark moles should not be treated. The pigmented marks that respond the best are superficial lesions such as those caused by sun damage (sun spots) and freckles.
The length and number of treatments will depend on the type and size of pigmented mark present, but typically 1-5 treatments will be needed. Treatments should take place approximately every 4 to 6 weeks.
The Intense Pulsed Light system releases yellow, green and red light that is emitted in a series of short pulses. The yellow/green light destroys the bacteria that live in the skin and cause acne, while the red light directly targets the overactive sebaceous glands that cause outbreaks of pustules. This targeted eating deep in the skin causes shrinkage of the inflamed sebaceous glands and helps to prevent over-production of excess sebum.
Almost everyone can be treated, except very dark skinned or tanned individuals. Pregnant women or people taking the acne treatment Roaccutane should not be treated.
