Introduction to Fluorescence Spectroscopy

Intense pulsed light (IPL) has been available to plastic surgeons since 1990. The latest, and most effective advancement in IPL lasers is calledAdvanced Fluorescence Technology (AFT)-designed to even out skin tone, particularly reds and browns. AFT lasers work by using both short and longlight wavelengths to rejuvenate the skin. According to the American Society for Aesthetic Plastic Surgery report released in 2010, 562,706 Laser skin-resurfacing procedures were performed in North America.
