Does laser hair removal cause hyperpigmentation?

I've seen so many reviews about laser hair removal treatments

Most people seemed very satisfied. However, I have one question.

Is it possible to experience discoloration or pigmentation after laser hair removal?

Usually, in the case of laser procedures, there is a concern about discoloration, so

I noticed that some people also get Vita Toning or Whitening care.

However, although the texture seems a bit different from that kind of laser, the laser hair removal itself is still

I was worried that it might get discolored or something like that.

Is it correct that it only provides semi-permanent hair removal?

Or, if there is a whitening treatment available, would it be better to get it together?

I'm curious to hear your review or if you recommend the whitening treatment!!
