Ok. So I didn't find these infomercials. I modified existing ones to advertise lasers (if that wasn't obvious to you) {sources 1, 2, 3}. But why shouldn't there be laser infomercials out there like these ones? I haven't run into any!
The reason for this is because applications of laser technology are not gimmicks. They actually work. There is a pretty long list of laser applications in all industries. Pertaining to health and medicine, here is a list of just a few that I know of:
Hair Removal
Stretch Mark Treatment
Scar Removal
Tattoo Removal
Teeth Whitening
Acne Treatment
Vision Enhancement Surgery
Bloodless Surgery Cutting Tools
If you were thinking about getting any of these done, don't search infomercials to find a solution. Be thankful that scientists and doctors are cooperating to extend the applications of lasers to cosmetic and health applications.
