The American Society for Aesthetic Plastic Surgery reported in 2014 that intense pulsed light (IPL) is a highly sought-after non-surgical procedure among plastic surgeons and other professionals. Although not a laser, IPL devices contain a powerful flashlamp that emits polychromatic, noncoherent light. With the ability to adjust for different wavelengths, fluences, and pulse durations, IPL treatment is effective in addressing vascular and pigmented lesions, photo damage, acne, and unwanted hair. IPL technology emits mid-infrared, noncoherent light, which can be customized with cutoff filters or separate handpieces based on skin type and chromophore absorption. The energy delivered and pulse duration can also be regulated for safe and efficient treatment. Modern IPL systems are greatly improved and calibrated to avoid bulb degradation. A rectangular light guide or crystal is used to deliver light to the skin, which is applied with gel to act as an optical and thermal coupler. For smaller areas, step-down adapters are available. IPL treatment is beneficial for various vascular conditions such as facial telangiectasia, poikiloderma of Civatte, superficial hemangiomas, and port wine stains, as well as photodamage, skin rejuvenation, and hair removal. However, IPL systems lack selectivity, posing a risk for epidermal melanin absorption and burns, especially in darker-skinned individuals. In summary, IPL technology is a versatile and popular solution for various skin concerns, delivering safe and effective results when used appropriately.
