We intend to perform a study with a device we developed (approved for medical research). The tests are non-invasive and only require a very low power laser to be exposed to the skin (complying with all the existing norms).
People will have to travel from their place to our facilities periodically to perform this test.
We want to publish the results of our study, but we are afraid that at the end the journal might require an ethical committee approval (which costs a lot of time and money).
In what cases shouldn't be necessary an ethical committee approval? Are there dermatology journals where this is not an issue for publication?
