Yeah, needless to say, the extra care is needed after the session.

But if you don't want to go to that extreme, there is an intermediate ground: just welts but w/o breaking the skin. It will just be a raised welt, no blood.

The breaking of the skin (and I don't like blood sport neither), only occurs:
-) repeatedly on the same spot
-) the cane is wide enough or the force is strong enough

The positive side is, when a cane is applied on a sub's ass, it takes say 30 sec., for the pain to grow from the time of impact, the feeling of that "growing" pain is very erotic, as it hurts more from the time of impact to the time when you feel the full extent of the pain.

Paddles, riding crops, doesn't give you that effect. The only way to find out is to try it once and you'll know what I mean.
