Looking at the history of shaving, I just realized that modern shaving with razors, safety razors, double-blade safety razors, triple-blade safety razors, ... are all very recent. Which got me questioning, what advances have been made for shaving by the 24th century.
So, the question is, in the Star Trek universe, how do people shave? Is there any mention of how such personal grooming in done? I do remember Tuvok shaving with a futuristic looking straight-edge razor in "Year of Hell: Part I" when he has been blinded. But how do people normally shave?
In-universe answer or an out-of-universe explanation is fine.
