is a registered nurse for laser hair removal the same as a physician?
physician is a medical doctor with a medical degree from a medical school. registered nurse is a nurse, i.e. someone who got some training and passed the registered nurse exam. so, no, it’s not the same thing.
btw, it’s not very important which of these is treating you. they don’t teach hair removal in either profession. you need someone who has specific experience in hair removal for best results.
