Intense pulsed light (IPL)
Intense pulsed light (IPL) uses a flashlamp to produce pulses across a range of wavelengths, with filters selecting the delivered light. A laser works differently. IPL and laser services may be grouped on clinic menus, but those names should not be used interchangeably. IPL may be proposed for different targets depending on the system and application.
What the label does not tell you
The term IPL does not identify the chosen filter, pulse sequence or goal. A single-subject study of treatment endpoints found that changes in wavelength selection and pulse parameters altered the skin response. That reinforces why a general light-treatment name cannot establish your risk or expected result. The device’s intended use, practitioner experience, your skin tone and recent sun exposure should be discussed together.
Questions to bring
Is this IPL or a laser and what exact system is used? What is the intended target and why is this approach suitable? Which factors in my skin history or medicines need a different plan? What eye protection and sun precautions are required? What discomfort, pigment changes or burns should prompt contact?
Evidence and scope
The endpoint study illustrates parameter effects in one person, rather than broad clinical efficacy or safety. IPL is not a laser and its wavelength range alone cannot establish which device is preferable.
