Many people get mad with us here when we say that no credential, no proof of having passed some standardized test can be taken as proof that one practitioner is better than another, and that only getting actual sample treatments, or seeing the results of clients/patients who are completed and happy with their results can possibly show you the actual skill of a practitioner, but it is really the truth. Being an RN doesn’t give her any special knowledge about hair removal. That training is separate (and frequently not equal 
).
