I doubt it. For nine years now I have been shaving with the most deshman "disposable" machines, the nastier of which probably will not affect the skin, moreover, due to some laziness and redneck, I stupidly scraped dry. True, not every day, but every two or three days, but still. And the skin in the shaved areas is still like a baby's on the buttocks.
Regular damage can make the skin harden, this is quite logical, since in order to protect against further damage, the skin becomes thicker and tougher. But in order to do this by shaving, you probably need to shave with your left leg. For all the time of my perverse practice of finding the fastest and cheapest way to shave, I cut myself only three times probably (and that was because of defective / damaged razors), although such horrors around show that horror takes.
... and from that all, I think, not because of the shaving itself, the skin coarsens, but because of the quality of the razors, the method of shaving, the level of skill and of course the genetic predisposition of the skin to rapid roughness with age and as a result of damage. p>
If you shave with an electric razor, then no, because it does not cut the skin.
The machine can spoil the skin a little, that's why they make all kinds of gels, lotions and foams. They don't help 100%. Often, those who shave all the time on their face have irritations and unhealthy skin, their cheeks still hang down red.
That's why I never use machines.
