Electric Razor - Takes a Month?

Do electric razors really take a month to start working while a person’s skin “learns” to adapt? Why is this?

In my experience it does take some time. I don’t remember it being as long as a month for me but it was at least a couple of weeks. Until then, I got small pimples and redness from it.

I don’t know why but I went through the same thing when I switched back to a razor.

I should add that by working, you meant to shave well then no. They do that right away as long as you know how to use them correctly. It is the irritation that takes time to go away.
