n00b question

hello,

this is a really n00b question:

I’ve recently started removing body hair as it is really annoying me. I tried shaving, didn’t work too well, left a lot of little dots.

Now i’m trying tweezing, which is slow (willing to put up with until i get an epilator). apparantly tweezing has a lot of bad side effects from what i’ve read here. But isn’t tweezing, waxing and epilating essentially the same? Why does tweezing result in scaring etc. while waxing and epilating does not?

Thanks!
