We don't get which condition you want to treat, because laser otherwise is deployed for treating many diseases, either those specific to dermatology, or those related to other medical fields as well.

Clinical trials involves participation of voluntary individuals who consent to being treated upon with new treatments so that it helps practitioners understand how effective they are, but otherwise, there's no other kind of "trial". And based on the context in which you put your question forth, we aren't able to understand what kind of trial option you want.

There could be alternatives, but for that we would want to know which condition you want to be treated for.

Please drop us a message specifying your matter of concern, take care!
