Intense Pulsed Light therapy is used in surgical, aesthetic, and cosmetic applications. The light energy is converted to heat energy to treat multiple skin conditions such as age spots, sun-damaged skin, arts, scars and reduce undesired hair growth. This noninvasive and nonablative treatment uses many wavelengths or colors of light. The FDA received several reports of patients sustaining second-degree burns after IPL therapy. Ensure that you check the device's calibration before every use or as often as recommended by the manufacturer. Contact the device manufacturer if you have any questions about maintaining and cleaning the device. The patient, who is taking medication should avoid IPL treatment because it could cause an undesired effect. Always make sure your facility's devices have been approved and permitted by the FDA to treat the multiple disorders.
