Theoretically the porphyrins in PCT are only activated around 400 nanometers - the end of the UVA range. IPL is visible light - starting at 400. However, definitions vary as to where UVA stops and visible light starts so I would stay away from any IPL treatment below 500 nanometers for sure. See a physician experienced with IPL who is willing to research this. If you were my patient I would do more research and also perform a test spot prior to treatment. Also, there may be other treatments to address you concerns - maybe you don't need IPL.
Best to you,
