It depends on the state where you live. You can seek specifics for your state from your state medical board. It's not always a matter of a specific licensure, but actually training for the unit, a good knowledge of how IPL works, and hands on experience. Just because someone is a physician or PA doesn't always mean they are "qualified" based on pure experience, and sometimes a laser tech has much more experience because they do these treatments every single day. I have 3 laser techs/MAs in my office to do IPL treatments and my office has performed over 150,000 IPLs in 13 years. However, I've probably done maybe 25 of those myself, and all of my techs far succeed me in this treatment. However, I'm still responsible for every treatment they do. But a basic type of license doesn't always mean that person is the best choice... It matters 1. who is allowed by state law, 2. who has actual experience and how much experience, and 3. how involved is the physician in your care and what happens if something goes wrong.
