Thank you for your question. There are really no restrictions on having IPL after Juvederm or Sculptra treatments - I have even treated patients with IPL on the same day, immediately after fillers. I would recommend scheduling a consultation with an experienced cosmetic dermatologist or plastic surgeon to discuss your concerns and come up with the best treatment plan for you. Best of luck!
There should be no problem of doing an IPL in close approximation to placing a filler. Make sure you see an expert injector (ExpertInjector.org)
